3PE anti-corrosion steel pipe anti-corrosion layer thickness standard

SY/T 0413-2002 Technical Standard for Polyethylene Anti-corrosion Layer of Buried Steel Pipeline Oil and Gas Industry Standard (SY) SY/T0413-2002 To ensure the quality of extruded polyethylene pipe anti-corrosion layer, prolong service life and improve Economic efficiency, this standard is specially formulated. This standard is applicable to the design, production and construction acceptance of extruded polyethylene pipe anti-corrosion coating. The extruded polyethylene anti-corrosion layer can be divided into a normal temperature type (N) with a long-term working temperature not exceeding 50 ° C and a high temperature type (H) with a long-term working temperature not exceeding 701 C.

Common anti-corrosion steel pipe anti-corrosion technology Daquan

Anti-corrosion steel pipe refers to a steel pipe that has been treated by anti-corrosion technology and can effectively prevent or slow down the corrosion phenomenon caused by chemical or electrochemical reaction during transportation and use. However, we do not fully understand the anti-corrosion methods and processes of various anti-corrosion steel pipes. For 2PE/3PE anti-corrosion, 2PP/3PP anti-corrosion, fire-proof pipeline buried anti-corrosion, steel-plastic composite pipe anti-corrosion, underground pipeline reinforcement grade anti-corrosion, epoxy coal anti-corrosion Introduction of several major anti-corrosion products such as steel pipe anti-corrosion and pe anti-corrosion steel pipe anti-corrosion.
