UNE-EN ISO 13680:2020

This document specifies the technical delivery conditions for corrosion-resistant alloy seamless tubularproducts for casing, tubing, coupling stock and accessory material for two product specification levels:çø PSL-1, which is the basis of this document;çø PSL-2, which provides additional requirements for a product that is intended to be both corrosionresistant and cracking resistant for the environments and qualification method specified inISO 15156 (all parts) and Annex G of this document.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 document are special alloys in accordance withISO 4948-1 and ISO 4948-2.NOTE 2 For the purpose of this document, NACE MR0175 is equivalent to ISO 15156 (all parts).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 duplexand 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 withaustenitic structure.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.NOTE 3 The connection or joining method can influence the corrosion performance of the materials specifiedin this document.NOTE 4 It is necessary to recognize that not all PSL-1 categories and grades can be made cracking resistant inaccordance with ISO 15156 (all parts) and are, therefore, not included in PSL-2.
