This document specifies the technical delivery conditions for corrosion-resistant alloy seamless
tubular products for casing, tubing, coupling stock and accessory material (including coupling stock
and accessory material from bar) for two product specification levels:
— PSL-1, which is the basis of this document;
— PSL-2, which provides additional requirements for a product that is intended to be both corrosion
and cracking resistant for the environments and qualification method specified in Annex G and in
the ISO 15156 series.
At the option of the manufacturer, PSL-2 products can be provided in lieu of PSL-1.
This document contains no provisions relating to the connection of individual lengths of pipe.
This document contains provisions relating to marking of tubing and casing after threading.
This document is applicable to the following five groups of products:
a) group 1, which is composed of stainless alloys with a martensitic or martensitic/ferritic structure;
b) group 2, which is composed of stainless alloys with a ferritic-austenitic structure, such as duplex
and super-duplex stainless alloy;
c) group 3, which is composed of stainless alloys with an austenitic structure (iron base);
d) group 4, which is composed of nickel-based alloys with an austenitic structure (nickel base);
e) group 5, which is composed of bar only (Annex F) in age-hardened (AH) nickel-based alloys with
austenitic structure.
