This document specifies the technical delivery conditions for corrosion-resistant alloy seamless tubular products for casing, tubing, coupling stock and accessory material 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 resistant and cracking resistant for the environments and qualification method specified in ISO 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 with ISO 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 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. 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. © ISO 2019 – All rights reserved ISO/DIS 13680:2019(E) ISO/DIS 13680:2018(E) 2 © ISO 2018 – All rights reserved NOTE 3 – The connection or joining method can influence the corrosion performance of the materials specified in this document. NOTE 4 – It is necessary to recognize that not all PSL-1 categories and grades can be made cracking resistant in accordance with ISO 15156 (all parts) and are, therefore, not included in PSL-2.
