What is ISO 13680 about?
ISO 13680 specifies the technical delivery conditions for corrosion-resistant alloy seamless tubular products for the casing, tubing, coupling stock, and accessory material (including coupling stock and accessory material from a bar) for two product specification levels:
- PSL-1, which is the basis of ISO 13680
- PSL-2 provides additional requirements for a product that is intended to be both corrosions and cracking resistance for the environments and qualification method specified in Annex G and the ISO 15156 series.
The corrosion-resistant alloys included in ISO 13680 are special alloys by ISO 4948-1 and ISO 4948-2. For ISO 13680, NACE MR0175 is equivalent to the ISO 15156 series. Accessory products can be manufactured from coupling stock and tubular material, solid bar stock, or bored and heat-treated bar stock as covered in Annex F.
ISO 13680 contains no provisions relating to the connection of individual lengths of pipe. ISO 13680 contains provisions relating to marking of tubing and casing after threading.
ISO 13680 applies to the following five groups of products:
- 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);
- group 5, which is composed of a bar only (Annex F) in age-hardened (AH) nickel-based alloys with austenitic structure.
Who is ISO 13680 for?
ISO 13680 on corrosion-resistant alloy seamless tubular products is relevant to:
- Manufacturer of seamless tubular products
- Petroleum and natural gas industries
- The Federal Energy Regulatory Commission
Why should you use ISO 13680?
Seamless tubes are as defined – they do not have a welded seam. Seamless steel pipe is used in many high-pressure, high-corrosive environments such as in the oil & gas, power generation, and pharmaceutical industries.
ISO 13680 provides information on the manufacturing process, material requirements, dimensions, masses and tolerances, inspection and testing, surface treatment required to manufacture corrosion-resistant alloy seamless tubular products for the casing, tubing, coupling stock, and accessory material.
As a user of ISO 13680, you can be ensured of the quality of the corrosion-resistant seamless alloy tubular casing, tubing, coupling stock, and accessory material used in Petroleum and natural gas industries that minimize the risk of leakage and contamination. As a result, ISO 13680 takes into account the safety and protection of the product end-user while also prolonging the service life of the alloy seamless tubular products. Moreover, guidance regarding the manufacturing process, material selection, inspection is provided by ISO 13680. Overall, with ISO 13680, you will be able to scale your business with globally accepted guidelines.
What’s changed since the last update?
BS EN ISO 13680:2020 supersedes BS EN ISO 13680:2010, which is withdrawn.
The main changes compared to the previous edition are as follows:
- Change of title and scope so that it includes accessory material and group 5
- Addition of new annex f(coupling blanks and accessory material from bar), annex h (standardized manufacturing procedure qualification test), and annex i(photographic examples of microstructures, groups 2, 3, and 4)
- Update of the warning statement
- Complete revision of the technical content
