1 Scope

This document specifies two product specification levels for casing, tubing, coupling blanks and accessory materials (including coupling blanks taken from bar stock and Accessory materials) Technical delivery conditions for corrosion-resistant alloy seamless pipes:

---PSL-1 is the basis of this document:

---PSL-2 puts forward additional requirements for products used to resist environmental corrosion and cracking: The assessment method is based on ISO 15156 (all parts) and given in Appendix A of this document:

At the manufacturer's option, PSL-2 products may be used in place of PSL-1 products:

Note 1: The corrosion-resistant alloys involved in this document refer to special alloys that comply with the regulations of ISO 4948-1 and ISO 4948-2:

Note 2: In this document, NACEMR0175 is equivalent to ISO 15156 (all parts):

This document does not contain provisions regarding single pipe connections:

This document contains provisions regarding post-machining marking of tubing and casing threads:

This document applies to the following five groups of products:

a) Group 1: Stainless alloys with martensite or martensite/ferrite structure;

b) Group 2: Stainless alloys with ferrite-austenite structure, such as duplex stainless alloys or super duplex stainless alloys;

c) Group 3: Iron-based stainless alloys with austenitic structure;

d) Group 4: Nickel-based alloys with austenitic structure;

e) Group 5: Age-hardened (AH) nickel-based alloy bar with austenitic structure (see Appendix B):

Note 3: Not all material types and strength levels of PSL-1 have cracking resistance in accordance with ISO 15156 (all parts) and, therefore, not all PSL-1 Material types and strength levels with PSL-1 can be included in PSL-2:
