Omfang

This European Standard contains requirements for the production and testing of weld joints for the installation and modification of onshore steel pipelines and pipework used in gas supply systems, including in-service pipelines, for all pressure ranges for the carriage of processed, non-toxic and non-corrosive natural gas according to ISO 13686, 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 supplying such premises; - the pipework is not located within household installations according to EN 1775:1998; - the design temperature of the system is between -40 °C and 120 °C inclusive. With respect to production and testing of welds, this European Standard refers to basic standards drafted by CEN/TC 121 and CEN/TC 138 as they exist up to the date of issue of this standard. This standard is not applicable to welds produced prior to the publication of this European standard. Clauses 4 to 9 describe general requirements which relate to all areas of application mentioned. The following clauses contain specific requirements: Clause 10: Supply systems for a maximum operating pressure up to and including 16 bar (distribution) Clause 11: Supply systems for a maximum operating pressure greater than 16 bar (transmission) Clause 12: Metering, regulating and compressor stations Table 1 assigns the application areas to quality requirement categories as a function of the working pressure and pipe materials used. Additional requirements may be specified when, for example - the strain on pipelines and systems; - the materials; - the line routing; - the design or the welding technique are considered critical. This European Standard specifies common basic principles for gas supply systems. Users of this European Standard should be aware that there can exist more detailed national standards and/or codes of practice in the CEN member countries. This European Standard 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 standard, the national legislation/regulation shall take precedence.
