ISO 13680:2010 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 ISO 13680:2010; 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 ISO 13680:2010.
At the option of the manufacturer, PSL-2 products can be provided in lieu of PSL-1.
The corrosion-resistant alloys included in ISO 13680:2010 are special alloys in accordance with ISO 4948-1 and ISO 4948-2.
ISO 13680:2010 is applicable to the following four groups of product: group 1, which is composed of stainless alloys with a martensitic or martensitic/ferritic structure; group 2, which is composed of stainless alloys with a ferritic-austenitic structure, such as duplex and super-duplex stainless alloy; group 3, which is composed of stainless alloys with an austenitic structure (iron base); group 4, which is composed of nickel-based alloys with an austenitic structure (nickel base).
ISO 13680:2010 contains no provisions relating to the connection of individual lengths of pipe.
