World-renowned Superbolt, Inc., got its start in Pittsburgh, Pa., USA, when the region was best known as America’s “Steel City”. In 1974, local inventor Rolf Steinbock was designing and building custom equipment for the steel industry. A local steel manufacturer purchased one of his designs, a scrap chopper, which solved problems that plagued older devices. But the new machine’s constant rotation tended to loosen critical bolts. Downtime for maintenance became a daily necessity, and it involved re-tightening with a heavy wrench and a sledge hammer. ________ THE MAN FROM PITTSBURGH WHO CHANGED BOLTING TECHNOLOGY FOREVER _________ 70,000 (50,000) 30 60 90 180120 150 TORQUE REQUIREMENTS FOR SUPERBOLT MULTI-JACKBOLT TENSIONERS 140,000 100,000)( The chart shows how Superbolt tensioners remain easy to install, even on larger sizes, compared to standard hex nuts. Only hand tools are required to tighten any diameter stud/bolt. TORQUE CURVE FOR 310 MPA (45,000 PSI) BOLT STRESS Mr. Steinbock took one look at this hazardous, repetitive chore and came up with a better idea: Instead of struggling with the massive torque of large hex nuts, why not divide the torque into multiple manageable forces? He sketched out the first multi-jackbolt tensioner (MJT) for fabrication by a local machine shop. With a set of MJTs installed, the scrap chopper’s bolts never came loose again. Mr. Steinbock patented his invention and founded Superbolt, Inc., in 1984 and in 1988 a sister company in Switzerland was founded. After almost three decades of growth, both companies became part of the Nord-Lock Group, the global leader in secure bolting solutions, in 2011. Ever since the introduction of the MJT, solving tough bolting challenges has been our quest. Today you can choose from an extensive range of standard and pre-engineered designs, within our portfolio or as a customized design, all based on decades of experience in tensioner technology.

98 The Superbolt Principle By tightening the jackbolts, a strong thrust (axial) force is generated. This thrust force is directed against a hardened washer. Jackbolts have a small friction diameter and can therefore create a high thrust force with relatively little torque input. 1 The loads are transferred through the nut body which is positioned on the main thread by hand. 2 A hardened washer is used to transfer the force while protecting the flange face. 3 The thrust (axial) force of jackbolts and the opposite reaction force of the main bolt head create a strong clamping force on the flange. 4 The thrust (axial) force from the jackbolt creates an equally strong reaction force in the main bolt. 5 DESIGN INITIAL INSTALLATION OPERATION MAINTENANCE A Full Lifespan of Advantages HIGHER PRELOAD Tightening in pure tension allows higher preloads with greater accuracy than other methods, making Superbolt MJTs the ideal choice. HAND TOOLS ONLY A single worker can torque or un-torque the most massive Superbolt assemblies with ordinary hand tools. HIGHER VIBRATION RESISTANCE Preloads that exceed separating forces prevent bolts from vibrating loose. EASY INSPECTION Torque checks can be done safely and easily, using only hand tools. CUSTOMER Superbolt tensioners are designed as direct replacements for conventional nuts and bolts. These devices can be threaded onto a new or existing bolt, stud, threaded rod or shaft. The main thread serves to position the tensioner on the bolt or stud against the hardened washer and the load- bearing surface. Once it is positioned, actual tensioning of the bolt or stud is accomplished with simple hand tools by torqueing the jackbolts which encircle the main thread. The jackbolts transfer the preload evenly into the main thread and, consequently, onto the joint. The main thread is tightened in pure tension. BETTER BOLTED JOINT Generating preload high enough above the separating forces means no loosening on properly designed joints. CUSTOM SOLUTIONS Custom products tailored to your application can accommodate demanding preload requirements, space restrictions, or harsh environments. GREATER SAFETY Superbolt tensioners eliminate dangerous pinch points, heavy- equipment lifts, or tool- shattering stresses. FEWER SPACE LIMITS Multi-jackbolt tensioners are easier to install in confined spaces. ACCURATETENSIONING Accurate, even tension from joint to joint ensures even loading and reduces the risk of leakage. GREATER RELIABILITY Accurate preloads prevent joint loosening, minimizing fatigue and prolonging bolt life. NO GALLING Tightening in pure tension eliminates thread galling that is common with direct-torque methods. QUICK DISASSEMBLY Easily removed MJTs reduce the expense of extended downtime associated with standard bolting methods. DESIGN OPTIONS High preload capacity and greater accuracy make smaller bolts feasible for your design. Reduced dimensions and tooling sizes can mean smaller devices that use less material and cost less to build. REDUCED CYCLE TIME You can tighten or remove Superbolt tensioners in a fraction of the time compared to other methods. Two or more technicians can work side-by-side using hand-held air or electric tools, further reducing cycle time. REDUCED DOWNTIME Properly designed and tightened joints stay secure in service, limiting maintenance- related downtime. REUSABILITY Superbolt tensioners are reusable. Preload can be restored anywhere with simple hand tools. THESUPERBOLTSTORY THESUPERBOLTSTORY

STUD BOLTS Superbolt nut-style tensioners may be used on studs into blind-tapped holes. Tightening in pure tension means studs will not gall in the tapped hole and can be easily removed. TAPPED HOLES Superbolt bolt-style tensioners are often used into blind- tapped holes. MJT bolt heads are more compact and fit into tighter areas; additionally they reduce the number of parts. THROUGH-HOLES A common application of double- ended studs uses Superbolt nut- style tensioners and a reaction nut (Flexnut) on the other end. Flexnuts add elasticity to the stud, increasing the fatigue life. COUNTER BORES Superbolt bolt-style tensioners can be provided to fit completely into small counterbores. An internal installation removal hex allows for easy turning into position. Joint design and installation ___ EXPERIENCED ENGINEERS AND TOTAL CUSTOMER SUPPORT ___ CENTERING OF WASHER ON THREAD Make sure the washer is not resting on one side of undercuts or radius of mating studs. MATERIAL WITH LOW STRENGTH A thicker/larger washer or an additional washer may be necessary when materials with low strength are used on the joint. LARGE OR SLOTTED HOLES An additional washer or a large washer is necessary to transfer the bolt load to a supported surface. SPACE REQUIREMENTS Check for space restrictions when using a socket and wrench combination. TENSIONER AT THE END OF STUD An additional distance spacer may be necessary to bring tensioner closer to the end of the stud for proper socket fit. VERY LONG THROUGH-STUD A special tensioner with a larger circle of jackbolts may be necessary to properly access the jackbolts for tightening.

REACTIVE SIDE SOLUTIONS Superbolt developed the Flexnut for through-hole applications. Flexnuts bring the advantages of MJT-type elasticity to the reactive side of the joint. Flexnuts are designed to flex out at the bottom and flex in toward the top of the nut. This distributes the bolt load along many threads, adds elasticity, and prevents stress concentrations in the first few threads. INSTALLATION TIP: Flexnuts are reactive nuts, designed to be applied opposite Superbolt tensioners. They are never torqued directly to achieve preload. Get design flexibility during installation Our design capabilities and quick service give you unequaled flexibility, for trouble-free installation. 3736 REACTIVESIDESOLUTIONS

COMPACT/LOW-PROFILE TENSIONERS You’re never limited with Superbolt technology. Over the decades, Superbolt and the Nord-Lock Group have solved millions of bolting challenges across a multitude of industries. We work closely with customers all over the world to ensure safety and reliability on the job. Height restrictions in applications make it difficult to preload joints adequately. That’s why Superbolt developed our range of low-profile tensioners, bringing all the advantages of a traditional MJT in a compact design. The SJ and SJX series can be used in general applications where height is a concern. SSJX bolt-style tensioners are designed to fit inside the same low-profile counterbore as standard socket-head cap screws.

DYNAMIC APPLICATIONS Custom-designed products When off-the-shelf parts just won’t do the job, you can rely on the Superbolt Technical Center to design and manufacture exactly what you need. We respond fast to keep your downtime to a minimum and get your equipment back up and running safely, efficiently, and cost-effectively. Generating correct preload forces for compressors and rotating equipment can be especially demanding. Superbolt tensioners for dynamic applications incorporate an added safety design feature – captive machinery-style jackbolts. Gain a competitive advantage with cross- head jamnuts (CN Series) for reciprocating compressor crossheads. Simple hand tools and an easy-to-follow specific installation procedure make CN a preferred solution. Piston-end nuts (SP Series) are specially designed to match the custom counterbore necessary dimensions of the nuts they replace. MR Series with captive tensioners replace the traditional MT Series for rotating equipment. The MRA Series – an armored-style tensioner with countersunk, captive jackbolts – is the solution for couplings and harsh environments. 4948 DYNAMICAPPLICATIONS COMMON APPLICATIONS Compressor crossheads Piston-end nuts Rotating equipment Mining Crushers Gearboxes Presses Bearing caps Coupling nuts Engines

Superbolt can help you solve just about any challenge on your compressor. Superbolt CN and SP custom tensioners are designed specifically for challenging reciprocating compressor applications. MR and MRA also feature captive jackbolts and are useful on many compressor applications, engines and couplings. MT Tensioner on Cylinder HeadsSP Tensioner on PistonFoundation Bolts Distance Piece SP Compressor Piston End Nut These custom-designed, nut-style tensioners are ideal for attaching compressor pistons to piston rods. There’s no need to clamp the rod when installing or removing Superbolt piston- end nuts, which incorporate captive jackbolts as an added safety feature. CN Tensioner on Crosshead CN Compressor Crosshead Jamnut CN compressor crosshead jamnuts are safe and easy to install or remove. Designed in collaboration with a major compressor manufacturer, they incorporate Superbolt captive jackbolts as an added safety feature. An extra-wide bolt circle positions jackbolts away from the piston rod for better wrench clearance.

CUTTING-EDGE SOLUTIONS Real-life testing and validation at your site Our skilled engineers can perform a thorough investigation of your bolted connections, including real-life tests or validation, at your site. Bolted connections are difficult to set up, maintain, and disassemble under normal conditions. Add challenges such as heat and pressure, and your job just got a whole lot tougher. As an example, forging presses must handle extraordinary forces routinely. But when you need to prestress or disconnect large-diameter columns and tie rods, you experience first-hand the giant gap between human-sized effort and the super- human torque that the job requires. Similarly, when your installation gets as hot as a reactor’s pressure vessel, you know ordinary nuts and bolts won’t give you the long-term security that safety and proper functioning require. Under extreme conditions, experienced plant engineers turn to Superbolt for high-preload, large-size, or heat-resistant tensioners that translate mechanical advantage into maintenance reductions, cost savings, and faster, safer operations. CUTTING-EDGESOLUTIONS 5554 Extreme requirements for any challenge Extreme industry applications Unique designs for your requirements SECTION INCLUDES
___ EXTREME REQUIREMENTS FOR ANY CHALLENGE___ Other bolting methods would be heavily challenged to solve the many bolting problems found in giant machines such as forging presses, cranes, or mining machines. All of these have large diameter nuts and bolts well over M100 (4 inch) that require extremely high preloads. Superbolt is right at home in these applications and still allows you to achieve the preload, getting the job done without increased hassle. Thread diameters of 1,5 M (60 inch) and with clamp ranges up to 90 MN (20 Mlbf) have been produced. Large diameters & high preload Superbolt STC Innovative and easy to use Split-Nut Thrust Collar (STC) tensioners are the perfect solution for large sized threads and high preload requirement applications. A threaded split nut (1) is positioned over a threadless ring (2). When tightened, the jackbolts – which are contained in the ring – push against a hardened washer (3) and cause the ring to thrust against the split nut, thereby preloading the joint. The installation is quicker and with less heavy turning equipment. CUTTING-EDGESOLUTIONS CUTTING-EDGESOLUTIONS 5756 No matter the environment, Superbolt has plenty of product-enhancing options to keep things protected. From stainless steels to various coatings, we can meet your requirements in humid environments, offshore & salt water splash zones or chemical exposure. In addition to corrosion protection, coatings can be beneficial for various purposes, e.g., color- coding, durability and conductivity enhancement, as well as friction control. Material Requirements, Environmental & Corrosion Protection Stainless materials adapted for the requirements: • Martensitic • Austenitic • Duplex • Precipitation hardened • Inconels & Monels Examples of coatings and platings including: • Electroless nickel • Xylan • Zinc • Black oxide • Zinc flake • PVC & metal caps Assembling an enormous 1016 mm (40 inch) thread tensioner, used on a 50,000 ton press. Extreme temperatures increase the complexity of bolting. Superbolt products are available in solutions to meet temperature ranges of -270°C (-450°F) to 600°C (1150°F). Due to the complexities of low- and high-temperature bolting, Superbolt offers a variety of solutions based on the temperatures and code requirements. Such cases are often found in power or petrochemical plants where extremely low temperatures (liquid hydrogen, fusion reactors, etc.) and extremely high temperatures (combustion chambers, turbines, steel mills, furnace equipment) exist. High- & low- temperature tensioners The world’s largest bolt-style Superbolt being installed in a two-post hydraulic forging press.
58 Particle Accelerators Superbolt provided over 1,400 nut-and-bolt-style tensioners and pins for securing the assembly of 30-foot diameter magnet endcap disks inside the underground tunnel that holds the collider. Large loads were required and only small spaces were available. Superbolt tensioners are ideal for nuclear plant critical and high- radiation applications. Significant savings in worker exposure and outage time are realized. Applications examples: valves, heaters, manways, pumps, turbines, shaftline couplings. Manufactured from approved materials. Nuclear Power Generation Space ___ EXTREME INDUSTRY APPLICATIONS ___ Defense Land, air or sea Superbolt tensioners are ideally suited for the many “can’t fail” extreme applications required for national defense.

They are shock-qualified and salt-waterproof, ideally suited for commercial marine, navy, and offshore applications. IT’S JUST ROCKET SCIENCE. Fusion Power Superbolts are ideal for Tokamak structures where there is a mixture of bolting complexity and extreme requirements. This means the need for precise material properties, meeting extreme bolt loads, working within limited spaces, and where both extremely high and low temperatures exist is now possible. Superbolt is ideally suited for applications like ITER. Superbolt is rocket science! Not that it is difficult to handle or use, but we have the bolting know- how that space environments require. We are useful on launch craft equipment, satellites, International Space Station (ISS), and many more. Since there are no torsion effects and only small handheld tooling is needed, the small torques on the jackbolts make bolting possible in non- gravity environments. Additionally, space- approved lubricants are utilized. CUTTING-EDGESOLUTIONS CUTTING-EDGESOLUTIONS Credit©ITEROrganization,http://www.iter.org/ 5958
CUTTING-EDGESOLUTIONS ___ UNIQUE DESIGNS FOR YOUR REQUIREMENTS___ Ever since the beginning, we have been proud of our ability to meet any bolting challenge. From engineering to design to manufacturing to installation, from our standard range, our pre-engineered range or customized solutions, we have the know-how to provide the right design for your application. The following are just a few examples of what we can do. CUTTING-EDGESOLUTIONS 61 An ETT is an externally threaded tensioner that provides a pushing force for loading or sealing a mating piece (compression member). Unlike conventional nut-style tensioners with an internal threaded portion and machined- surface outer diameter, an ETT has its threads machined onto the outer diameter. The ETT can be solid or hollow (i.e. bored center hole but unthreaded). The ETTs use multi-jackbolt technology to generate compression loads for assembly components in machinery. They simply are turned into position. A large hex or some other provided turning tool is used to facilitate nut turn-down. The jackbolts, which are tightened to a prescribed torque with low-energy handheld tools, push directly against the loading piece. Strong compression or sealing forces are generated. Externally Threaded Tensioners (ETT) Tamper- proof tensioners Superboltoffers a tamper-resistant jackbolt design. The tamper-resistant jackbolts are a product improve- ment for Superbolt’s multi-jackbolt tensioner (MJT) bolting system and are intended for use in security- sensitive applications. Tamper-resistant jackbolts are designed to protect MJTs from unwanted tightening and loosening. They utilize an abnormally shaped head set in a counter-bore hole, which requires a special tool attachment to torque or un-torque the jackbolts.

  • 4. World-renowned Superbolt, Inc., got its start in Pittsburgh, Pa., USA, when the region was best known as America’s “Steel City”. In 1974, local inventor Rolf Steinbock was designing and building custom equipment for the steel industry. A local steel manufacturer purchased one of his designs, a scrap chopper, which solved problems that plagued older devices. But the new machine’s constant rotation tended to loosen critical bolts. Downtime for maintenance became a daily necessity, and it involved re-tightening with a heavy wrench and a sledge hammer. ________ THE MAN FROM PITTSBURGH WHO CHANGED BOLTING TECHNOLOGY FOREVER _________ 70,000 (50,000) 30 60 90 180120 150 TORQUE REQUIREMENTS FOR SUPERBOLT MULTI-JACKBOLT TENSIONERS 140,000 100,000)( The chart shows how Superbolt tensioners remain easy to install, even on larger sizes, compared to standard hex nuts. Only hand tools are required to tighten any diameter stud/bolt. TORQUE CURVE FOR 310 MPA (45,000 PSI) BOLT STRESS Mr. Steinbock took one look at this hazardous, repetitive chore and came up with a better idea: Instead of struggling with the massive torque of large hex nuts, why not divide the torque into multiple manageable forces? He sketched out the first multi-jackbolt tensioner (MJT) for fabrication by a local machine shop. With a set of MJTs installed, the scrap chopper’s bolts never came loose again. Mr. Steinbock patented his invention and founded Superbolt, Inc., in 1984 and in 1988 a sister company in Switzerland was founded. After almost three decades of growth, both companies became part of the Nord-Lock Group, the global leader in secure bolting solutions, in 2011. Ever since the introduction of the MJT, solving tough bolting challenges has been our quest. Today you can choose from an extensive range of standard and pre-engineered designs, within our portfolio or as a customized design, all based on decades of experience in tensioner technology.

  • 5. 98 The Superbolt Principle By tightening the jackbolts, a strong thrust (axial) force is generated. This thrust force is directed against a hardened washer. Jackbolts have a small friction diameter and can therefore create a high thrust force with relatively little torque input. 1 The loads are transferred through the nut body which is positioned on the main thread by hand. 2 A hardened washer is used to transfer the force while protecting the flange face. 3 The thrust (axial) force of jackbolts and the opposite reaction force of the main bolt head create a strong clamping force on the flange. 4 The thrust (axial) force from the jackbolt creates an equally strong reaction force in the main bolt. 5 DESIGN INITIAL INSTALLATION OPERATION MAINTENANCE A Full Lifespan of Advantages HIGHER PRELOAD Tightening in pure tension allows higher preloads with greater accuracy than other methods, making Superbolt MJTs the ideal choice. HAND TOOLS ONLY A single worker can torque or un-torque the most massive Superbolt assemblies with ordinary hand tools. HIGHER VIBRATION RESISTANCE Preloads that exceed separating forces prevent bolts from vibrating loose. EASY INSPECTION Torque checks can be done safely and easily, using only hand tools. CUSTOMER Superbolt tensioners are designed as direct replacements for conventional nuts and bolts. These devices can be threaded onto a new or existing bolt, stud, threaded rod or shaft. The main thread serves to position the tensioner on the bolt or stud against the hardened washer and the load- bearing surface. Once it is positioned, actual tensioning of the bolt or stud is accomplished with simple hand tools by torqueing the jackbolts which encircle the main thread. The jackbolts transfer the preload evenly into the main thread and, consequently, onto the joint. The main thread is tightened in pure tension. BETTER BOLTED JOINT Generating preload high enough above the separating forces means no loosening on properly designed joints. CUSTOM SOLUTIONS Custom products tailored to your application can accommodate demanding preload requirements, space restrictions, or harsh environments. GREATER SAFETY Superbolt tensioners eliminate dangerous pinch points, heavy- equipment lifts, or tool- shattering stresses. FEWER SPACE LIMITS Multi-jackbolt tensioners are easier to install in confined spaces. ACCURATETENSIONING Accurate, even tension from joint to joint ensures even loading and reduces the risk of leakage. GREATER RELIABILITY Accurate preloads prevent joint loosening, minimizing fatigue and prolonging bolt life. NO GALLING Tightening in pure tension eliminates thread galling that is common with direct-torque methods. QUICK DISASSEMBLY Easily removed MJTs reduce the expense of extended downtime associated with standard bolting methods. DESIGN OPTIONS High preload capacity and greater accuracy make smaller bolts feasible for your design. Reduced dimensions and tooling sizes can mean smaller devices that use less material and cost less to build. REDUCED CYCLE TIME You can tighten or remove Superbolt tensioners in a fraction of the time compared to other methods. Two or more technicians can work side-by-side using hand-held air or electric tools, further reducing cycle time. REDUCED DOWNTIME Properly designed and tightened joints stay secure in service, limiting maintenance- related downtime. REUSABILITY Superbolt tensioners are reusable. Preload can be restored anywhere with simple hand tools. THESUPERBOLTSTORY THESUPERBOLTSTORY

STUD BOLTS Superbolt nut-style tensioners may be used on studs into blind-tapped holes. Tightening in pure tension means studs will not gall in the tapped hole and can be easily removed. TAPPED HOLES Superbolt bolt-style tensioners are often used into blind- tapped holes. MJT bolt heads are more compact and fit into tighter areas; additionally they reduce the number of parts. THROUGH-HOLES A common application of double- ended studs uses Superbolt nut- style tensioners and a reaction nut (Flexnut) on the other end. Flexnuts add elasticity to the stud, increasing the fatigue life. COUNTER BORES Superbolt bolt-style tensioners can be provided to fit completely into small counterbores. An internal installation removal hex allows for easy turning into position. Joint design and installation ___ EXPERIENCED ENGINEERS AND TOTAL CUSTOMER SUPPORT ___ CENTERING OF WASHER ON THREAD Make sure the washer is not resting on one side of undercuts or radius of mating studs. MATERIAL WITH LOW STRENGTH A thicker/larger washer or an additional washer may be necessary when materials with low strength are used on the joint. LARGE OR SLOTTED HOLES An additional washer or a large washer is necessary to transfer the bolt load to a supported surface. SPACE REQUIREMENTS Check for space restrictions when using a socket and wrench combination. TENSIONER AT THE END OF STUD An additional distance spacer may be necessary to bring tensioner closer to the end of the stud for proper socket fit. VERY LONG THROUGH-STUD A special tensioner with a larger circle of jackbolts may be necessary to properly access the jackbolts for tightening.

  • 19. REACTIVE SIDE SOLUTIONS Superbolt developed the Flexnut for through-hole applications. Flexnuts bring the advantages of MJT-type elasticity to the reactive side of the joint. Flexnuts are designed to flex out at the bottom and flex in toward the top of the nut. This distributes the bolt load along many threads, adds elasticity, and prevents stress concentrations in the first few threads. INSTALLATION TIP: Flexnuts are reactive nuts, designed to be applied opposite Superbolt tensioners. They are never torqued directly to achieve preload.

  • 21. COMPACT/LOW-PROFILE TENSIONERS You’re never limited with Superbolt technology. Over the decades, Superbolt and the Nord-Lock Group have solved millions of bolting challenges across a multitude of industries. We work closely with customers all over the world to ensure safety and reliability on the job. Height restrictions in applications make it difficult to preload joints adequately. That’s why Superbolt developed our range of low-profile tensioners, bringing all the advantages of a traditional MJT in a compact design. The SJ and SJX series can be used in general applications where height is a concern. SSJX bolt-style tensioners are designed to fit inside the same low-profile counterbore as standard socket-head cap screws. The NM and NI series are designed as direct replacements for many standard series bearing locknuts and include a locking side-screw to secure tensioners to shafts.

  • 25. DYNAMIC APPLICATIONS Custom-designed products When off-the-shelf parts just won’t do the job, you can rely on the Superbolt Technical Center to design and manufacture exactly what you need. We respond fast to keep your downtime to a minimum and get your equipment back up and running safely, efficiently, and cost-effectively. Generating correct preload forces for compressors and rotating equipment can be especially demanding. Superbolt tensioners for dynamic applications incorporate an added safety design feature – captive machinery-style jackbolts. Gain a competitive advantage with cross- head jamnuts (CN Series) for reciprocating compressor crossheads. Simple hand tools and an easy-to-follow specific installation procedure make CN a preferred solution. Piston-end nuts (SP Series) are specially designed to match the custom counterbore necessary dimensions of the nuts they replace. MR Series with captive tensioners replace the traditional MT Series for rotating equipment. The MRA Series – an armored-style tensioner with countersunk, captive jackbolts – is the solution for couplings and harsh environments. 4948 DYNAMICAPPLICATIONS COMMON APPLICATIONS Compressor crossheads Piston-end nuts Rotating equipment Mining Crushers Gearboxes Presses Bearing caps Coupling nuts Engines

Superbolt can help you solve just about any challenge on your compressor. Superbolt CN and SP custom tensioners are designed specifically for challenging reciprocating compressor applications. MR and MRA also feature captive jackbolts and are useful on many compressor applications, engines and couplings. MT Tensioner on Cylinder HeadsSP Tensioner on PistonFoundation Bolts Distance Piece SP Compressor Piston End Nut These custom-designed, nut-style tensioners are ideal for attaching compressor pistons to piston rods. There’s no need to clamp the rod when installing or removing Superbolt piston- end nuts, which incorporate captive jackbolts as an added safety feature. CN Tensioner on Crosshead CN Compressor Crosshead Jamnut CN compressor crosshead jamnuts are safe and easy to install or remove. Designed in collaboration with a major compressor manufacturer, they incorporate Superbolt captive jackbolts as an added safety feature. An extra-wide bolt circle positions jackbolts away from the piston rod for better wrench clearance.

  • 28. CUTTING-EDGE SOLUTIONS Real-life testing and validation at your site Our skilled engineers can perform a thorough investigation of your bolted connections, including real-life tests or validation, at your site. Bolted connections are difficult to set up, maintain, and disassemble under normal conditions. Add challenges such as heat and pressure, and your job just got a whole lot tougher. As an example, forging presses must handle extraordinary forces routinely. But when you need to prestress or disconnect large-diameter columns and tie rods, you experience first-hand the giant gap between human-sized effort and the super- human torque that the job requires. Similarly, when your installation gets as hot as a reactor’s pressure vessel, you know ordinary nuts and bolts won’t give you the long-term security that safety and proper functioning require. Under extreme conditions, experienced plant engineers turn to Superbolt for high-preload, large-size, or heat-resistant tensioners that translate mechanical advantage into maintenance reductions, cost savings, and faster, safer operations.

  • 29. ___ EXTREME REQUIREMENTS FOR ANY CHALLENGE___ Other bolting methods would be heavily challenged to solve the many bolting problems found in giant machines such as forging presses, cranes, or mining machines. All of these have large diameter nuts and bolts well over M100 (4 inch) that require extremely high preloads. Superbolt is right at home in these applications and still allows you to achieve the preload, getting the job done without increased hassle. Thread diameters of 1,5 M (60 inch) and with clamp ranges up to 90 MN (20 Mlbf) have been produced. Large diameters & high preload Superbolt STC Innovative and easy to use Split-Nut Thrust Collar (STC) tensioners are the perfect solution for large sized threads and high preload requirement applications. A threaded split nut (1) is positioned over a threadless ring (2). When tightened, the jackbolts – which are contained in the ring – push against a hardened washer (3) and cause the ring to thrust against the split nut, thereby preloading the joint. The installation is quicker and with less heavy turning equipment. CUTTING-EDGESOLUTIONS CUTTING-EDGESOLUTIONS 5756 No matter the environment, Superbolt has plenty of product-enhancing options to keep things protected. From stainless steels to various coatings, we can meet your requirements in humid environments, offshore & salt water splash zones or chemical exposure. In addition to corrosion protection, coatings can be beneficial for various purposes, e.g., color- coding, durability and conductivity enhancement, as well as friction control. Material Requirements, Environmental & Corrosion Protection Stainless materials adapted for the requirements: • Martensitic • Austenitic • Duplex • Precipitation hardened • Inconels & Monels Examples of coatings and platings including: • Electroless nickel • Xylan • Zinc • Black oxide • Zinc flake • PVC & metal caps Assembling an enormous 1016 mm (40 inch) thread tensioner, used on a 50,000 ton press. Extreme temperatures increase the complexity of bolting. Superbolt products are available in solutions to meet temperature ranges of -270°C (-450°F) to 600°C (1150°F). Due to the complexities of low- and high-temperature bolting, Superbolt offers a variety of solutions based on the temperatures and code requirements. Such cases are often found in power or petrochemical plants where extremely low temperatures (liquid hydrogen, fusion reactors, etc.) and extremely high temperatures (combustion chambers, turbines, steel mills, furnace equipment) exist.

They are shock-qualified and salt-waterproof, ideally suited for commercial marine, navy, and offshore applications. IT’S JUST ROCKET SCIENCE. Fusion Power Superbolts are ideal for Tokamak structures where there is a mixture of bolting complexity and extreme requirements. This means the need for precise material properties, meeting extreme bolt loads, working within limited spaces, and where both extremely high and low temperatures exist is now possible. Superbolt is ideally suited for applications like ITER. Superbolt is rocket science! Not that it is difficult to handle or use, but we have the bolting know- how that space environments require. We are useful on launch craft equipment, satellites, International Space Station (ISS), and many more. Since there are no torsion effects and only small handheld tooling is needed, the small torques on the jackbolts make bolting possible in non- gravity environments. Additionally, space- approved lubricants are utilized. CUTTING-EDGESOLUTIONS CUTTING-EDGESOLUTIONS Credit©ITEROrganization,http://www.iter.org/ 5958
  • 31. CUTTING-EDGESOLUTIONS ___ UNIQUE DESIGNS FOR YOUR REQUIREMENTS___ Ever since the beginning, we have been proud of our ability to meet any bolting challenge. From engineering to design to manufacturing to installation, from our standard range, our pre-engineered range or customized solutions, we have the know-how to provide the right design for your application. The following are just a few examples of what we can do. CUTTING-EDGESOLUTIONS 61 An ETT is an externally threaded tensioner that provides a pushing force for loading or sealing a mating piece (compression member). Unlike conventional nut-style tensioners with an internal threaded portion and machined- surface outer diameter, an ETT has its threads machined onto the outer diameter. The ETT can be solid or hollow (i.e. bored center hole but unthreaded). The ETTs use multi-jackbolt technology to generate compression loads for assembly components in machinery. They simply are turned into position. A large hex or some other provided turning tool is used to facilitate nut turn-down. The jackbolts, which are tightened to a prescribed torque with low-energy handheld tools, push directly against the loading piece. Strong compression or sealing forces are generated. Externally Threaded Tensioners (ETT) Tamper- proof tensioners Superboltoffers a tamper-resistant jackbolt design. The tamper-resistant jackbolts are a product improve- ment for Superbolt’s multi-jackbolt tensioner (MJT) bolting system and are intended for use in security- sensitive applications. Tamper-resistant jackbolts are designed to protect MJTs from unwanted tightening and loosening. They utilize an abnormally shaped head set in a counter-bore hole, which requires a special tool attachment to torque or un-torque the jackbolts. SU PERBOLT.COM WE´LLHELPYOUFI NDTHERIGHTPRODU CTFORYOURAPPLIC ATION OPTIMUMDESIGN! Offshore/Sub-sea Superbolt offers a unique combination of features built into this specialized multi-jackbolt tensioner for offshore bolting applications. It incorporates three key features: 1) The washer is captive to the nut body to prevent loss of the washer, 2) corrosion protection to address the harsh conditions, and 3) integral flats on the nut for turning assistance on difficult stud threads. Customized studs We sell a majority of tensioners, but also offer one-source shopping for your entire joint hardware. We offer customized studs to meet and deliver a complete bolted package. We have comprehensive threading know-how and an extensive inventory of gaging equipment. Why not choose a Superbolt nut-style tensioner, stud and flexnut kit?

The key is a patented design that divides the load among multiple small jackbolts, giving you an overwhelming mechanical advantage. Connections stay tight indefinitely, yet a single worker can torque or un-torque the most massive assemblies with ordinary hand tools. The Nord-Lock Group is focused on solving the toughest bolting challenges.
