API SPEC 5CRA
Specification for Corrosion-resistant Alloy Seamless Tubes for Use as Casing, Tubing, and Coupling Stock
|Publication Date:||1 February 2010|
This International Standard specifies the technical delivery conditions for corrosion-resistant alloy seamless tubulars for casing, tubing and coupling stock for two product specification levels:
⎯ PSL-1, which is the basis of this International Standard;
⎯ PSL-2, which provides additional requirements for a product that is intended to be both corrosion resistant and cracking resistant for the environments and qualification method specified in ISO 15156-3 and Annex G of this International Standard.
At the option of the manufacturer, PSL-2 products can be provided in lieu of PSL-1.
NOTE 1 The corrosion-resistant alloys included in this International Standard are special alloys in accordance with ISO 4948-1 and ISO 4948-2.
This International Standard is applicable to the following four groups of product:
a) group 1, which is comprised of stainless alloys with a martensitic or martensitic/ferritic
b) group 2, which is comprised of stainless alloys with a ferritic-austenitic structure, such as duplex and superduplex stainless alloy;
c) group 3, which is comprised of stainless alloys with an austenitic structure (iron base);
d) group 4, which is comprised of nickel-based alloys with an austenitic structure (nickel base).
This International Standard contains no provisions relating to the connection of individual lengths of pipe.
NOTE 2 The connection or joining method can influence the corrosion performance of the materials specified in this International Standard.
NOTE 3 It is necessary to recognize that not all PSL-1 categories and grades can be made cracking resistant per ISO 15156-3 and are, therefore, not included in PSL-2.
