Visual Inspection — Non-Destructive (X-Ray) Testing is Unnecessary Advantages of Lokring Fittings (Detailed documentation at www.lokring.com) Anti-Torque Seal Fitting Body Main Seal Isolation/Outboard Seal Pipe Tool Flange Primary/Inboard Seal Driver/Swage Ring Uninstalled Installed Elastic Strain Preload (ESP® ) Techology During installation, the axial movement of the LOKRING™ driver over the fitting body swages the body onto the pipe surface, compressing the pipe wall first elastically and then plastically. The pipe wall resists this swaging action, generating high unit compressive loads at the contact points between narrow sealing lands inside the fitting body and the pipe surface. These contact stresses are sufficiently high to plastically yield the pipe surface under the multiple sealing lands, forming a 360 degree circumferential, permanent, metal-to-metal seal between the pipe and fitting body. The driver, which experiences a small increase in diameter (elastic strain) during installation, exerts an elastic, radial pre-load on the metallic seals for the life of the connection. Air Resources Board Alan C. Lloyd Ph.D Chairman 2020 L Street - P.O. Box 2815 - Sacramento, California 95812 - www-arb.ca.gov LOKRING Meets the Strictest Air Resource Board Qualification (California) In confined spaces In all weather conditions Underwater On small or large projects On jobs where flammable or explosive conditions may exist On jobs where plant downtime is costly and problematic On jobs that require working with medical gas systems For quick and easy repair/rework To free up ASME-certified welders for large bore pipe or pressure vessel welding WHEN and WHERE Should LOKRING Fittings Be Used? No other connector (flanged or threaded) is capable of passing helium leak testing anywhere close to the level of a LOKRING fitting. LOKRING was independently tested to 2X10-11 atmosphere cc/sec Helium leak rate. In fact, the fitting meets all the criteria of a welded connection, except that no heat is required to make the connection. The quality of a LOKRING connection has now been recognized by the California Air Resources Board (CARB). CARB, through their equipment and process pre-certification program has granted LOKRING pre-certification status through executive order G-096-029-R03. The California Air Resources Board through their evaluation program has given LOKRING equivalent to WELDED status.

Technical Approvals/Qualifications ASME B31 Qualifications and Testing ISO 9001:2000 Certified British Ministry of Defence Lloyd’s Register #98-60070(E1) CRN #0A0481 TSSA-QA 00899 Hartford Boiler CSA-B51-95 API-607 Rev 4 Fire Test ASTM-F1387 NAVSEA ANSI/ASME B31.1, B31.3 Association of American Railroads U.S. Coast Guard NFPA 30 California Air Resources Board American Bureau of Shipping NFPA 99 Both stainless and carbon steel LOKRING fittings are qualified to the requirements of the ASME B31.1 and B-31.3 pressure piping codes for pressure and fatigue design and materials of construction. Extensive mechanical and environmental testing has demonstrated the mechanical and sealing integrity of the LOKRING connection in a wide range of applications and environmental conditions. Fire Testing:Pressure-Torsion Testing: Flexural Testing: Close-Up Figure 3: Fire Testing The metal-to-metal LOKRING seal remains intact when subjected to extreme thermal loads, including fire (above). Stainless and carbon steel LOKRING fittings are qualified to the API-607 Rev 4, fire test standards. Stainless steel fittings and CuNi 90/10 and 70/30 are also qualified to F1387 (U.S. Navy) fire test standards. Both are widely used on volatile and flammable services. Figure 2: Fatigue testing The 2” NPS carbon steel coupling above has been deflected to 3x the yield strength of the matching pipe without leaking. The performance of this fitting in severe bending, fatigue, and vibration loads is comparable or superior to a socket weld fitting. Figure 1: ASME testing The 1/2” NPS stainless steel test fitting was subjected to torsional loading high enough to twist the pipe in a spiral without leakage of the joint. Afterwards, during hydraulic testing, the pipe ruptured at 22,000 psi (1497 bar). Page 4

Easy Installation Twice the Productivity of Welded Pipe By eliminating welding in the unit, many overhead costs relating to safety, personnel, equipment and supplies, inspection, rework, and monitoring can be eliminated or substantially reduced. :Some examples are Obtain fire permit for hot work Erect scaffolding and provide ventilation "Sniff" area, gas free and weather protect Blank flanges and nozzles Establish fire watch Build fire box or tarps Drain, flush and dry lines Place equipment, electric cables, and purge line Cranes, welders, grinders and small tools Weld consumables (purge gas and filler rod) Workers' compensation, insurance and benefits Weld X-ray or other NDT Rework of damaged or misaligned spools System soak, flush, or passivation; HAZMAT disposal Maintain and monitor flanges for leakage Without the Welding Overhead In addition, ASME-certified welders are freed up for large bore pipe or pressure vessel welding. 51 2 Cut and prep pipe/tube. Inspect, gauge and mark pipe/tube ends. 3 4 Select and assemble LOKTOOL™. Actuate tool to install fitting. Remove LOKRING tool head. Inspect completed job. A fitter/helper team can routinely field erect, fit-up, and install 50 to 60 LOKRING fittings in a single shift. This productivity more than doubles the rate at which welded piping systems are typically shop fabricated and field erected. The increased productivity for a typical job equals $300.00 savings for every $1000.00 of the project’s cost. This combination of greater productivity and lower man-hour rates translates to approximately 250% more fittings per hour using LOKRING.
