FOREWORD

NORSOK (The competitive standing of the Norwegian offshore sector) is the industry initiative to
add value, reduce cost and lead time and remove unnecessary activities in offshore field
developments and operations.

The NORSOK standards are developed by the Norwegian petroleum industry as a part of the
NORSOK initiative and are jointly issued by OLF (The Norwegian Oil Industry Association) and
TBL (Federation of Norwegian Engineering Industries). NORSOK standards are administered by
NTS (Norwegian Technology Standards Institution).

The purpose of this industry standard is to replace the individual oil company specifications for use
in existing and future petroleum industry developments, subject to the individual company's review
and application.

The NORSOK standards make extensive references to international standards. Where relevant, the
contents of this standard will be used to provide input to the international standardisation process.
Subjec to implementation into international standards, this NORSOK standard will be withdrawn.

INTRODUCTION

This revision replace NORSOK standard M-CR-630, rev. 1, and the changes from rev. 1 to rev. 2
are mainly:
• more precise test requirements
• in some cases, increased extent of NDT
The acceptance criteria have not been changed.

MINOR DEVIATIONS FROM ASME B31.1 CODE REQUIREMENTS

The use of the piping materials according to NORSOK Standards (L-CR-001, M-630 and M-601)
will result in some minor deviations from the ASME B31.3 code. All deviations have been carefully
considered, and they are in line with Norwegian and European practice. The deviations are:

• NORSOK have of practical reasons limited the thickness for requiring impact testing to 6 mm
• If subsize Charpy V-notch impact test specimens are used, the energy requirement is increased
instead of lowering the test temperature.
• Impact testing is not required in the qualification of the welding procedures for weldments in
austenitic stainless steel when used in the temperature range from – 29 °C to – 105 °C.
• Eddy current examination is accepted as replacement for spot radiography of stainless steel welds
for wall thicknesses less than 4.0 mm.
• Thin walled (thickness up to 7 mm) longitudinal welded pipes in 6 Mo austenitic stainless is
accepted in as welded condition provided the plate material used is solution annealed.

In general, the MDS have supplementary requirement beyond the ASTM standard to ensure a proper
safety level.



1 SCOPE

This standard includes material requirement in a collection of Piping Material Data Sheets (MDS)
for use in piping systems, selected according to NORSOK L-CR-001, Piping and Valves.

The standards listed in the attached data sheets include provisions which constitute provisions of
this NORSOK standard. Latest issue of the references shall be used unless otherwise agreed. Other
recognized standards may be used provided it can be shown that they meet or exceed the
requirements of the standards referenced below.

4.1 General
Materials/components manufactured in accordance with M-CR-630 rev. 1 may be accepted. This
shall be agreed with the actual project/company.

The material selection menu for material standards and grades relevant for the piping systems is
shown in Table 1. The actual grades to be used with respect to piping design shall be stated on the
piping class sheet.

The materials shall be delivered in accordance with the standard referred to. In addition the MDS
specifies the selected options in the referred standard and additional requirements which shall be
added or supersede the corresponding requirements in the referred standard.

The actual types of materials covered are as follow:

C - Carbon steels; Type 235, Type 235LT, Type 360LT
D - Ferritic/Austenitic Stainless Steels; Type 22Cr, Type 25Cr
K - Copper/Nickel 90/10 and other copper alloys

Note: Welded products according to MDS D42, D43, D52, D53, R12, R13, S01 and T01 have
acceptance classes which give welding factors 0.8 and 1.0. The correct class is specified on
the piping class sheet. The order shall include acceptable classes.
