DANSK DSF/ISO/DIS 13680 PDF

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.
