NEN-EN 12732

Gas infrastructure - Welding steel pipework - Functional requirements

active, Most Current
Organization: NEN
Publication Date: 1 November 2021
Status: active
Page Count: 84
ICS Code (Welded joints and welds): 25.160.40
scope:

This document contains requirements for the production and testing of weld joints for the installation and modification, including in-service welding, of onshore steel pipelines and pipework used in gas infrastructure. This includes all pressure ranges and processed, non-toxic and non-corrosive natural gas according to EN ISO 13686 and non-conventional gases such as (injected) biomethane and hydrogen, where:

• the pipeline elements are made of unalloyed or low-alloyed carbon steel;

• the pipeline is not located within commercial or industrial premises as integral part of the industrial process on those premises except for any pipelines and facilities delivering gas to such premises;

• the pipework is not located within households or industrial installations according to EN 1775 or EN 15001;

• the design temperature of the system is between −40 °C up to and including 120 °C.

For injected biomethane or hydrogen a detailed technical evaluation of the functional requirements is required, ensuring there are no other constituents or properties of the gases that can affect the integrity of the pipeline.

This document is not applicable to welds produced prior to the publication of this document.

This document specifies common basic principles for gas infrastructure. Users of this document are expected to be aware that there can exist more detailed national standards and/or codes of practice in the CEN member countries.

This document is intended to be applied in association with these national standards and/or codes of practice setting out the above-mentioned basic principles.

In the event of conflicts in terms of more restrictive requirements in national legislation/regulation with the requirements of this document, the national legislation/regulation takes precedence as illustrated in CEN/TR 13737 (all parts).

NOTE CEN/TR 13737 (all parts) contains:

• clarification of relevant legislation/regulations applicable in a country;

• if appropriate, more restrictive national requirements;

• national contact point for the latest information.
