What are the specifications for long-distance transmission systems?
Thread Content
I’m not sure if anyone in the forum has already compiled these guidelines.:)
-ISO 3183: Steel pipes for linepipe (including X120) systems used in pipeline transportation 2 – ISO 13623: Pipelines for long-distance transmission systems – ISO 13847: Pipeline welding – ISO 14313: Pipeline valves – ISO 14723: Subsea pipeline valves – ISO 15889: Cathodic protection – ISO 15590: Induction bends, fittings, and flanges – ISO 21329: Mechanical connectors. I hope this information is helpful to you
Mainly GB50251 \"Code for Design of Oil Pipeline Engineering\" and GB50253 \"Code for Design of Gas Pipeline Engineering\"! ! Public pipelines: GB50028 \"Code for Design of Urban Gas Systems\"! ! For reference only! ! ! :handshake :victory:
In addition to ISO, there should also be APIs and European standards
Above, they mentioned the design specifications; the acceptance specifications include: GB50369-2006, SY0401-98, SY/T 0429-2000, SY/T4079-95, GB50423-2007, SY/T4109-2005
SY0401-98 has been replaced by GB50369-2006
The pipeline specification has been revised in 2006; the cross-border specification has a new version as well, and the construction and acceptance specifications have also been updated. Most of the above specifications are available on this forum; you can search for them. It is said that a new version of the specifications for steel pipe anti-corrosion will also be released.
