SY/T 0413-2002 buried steel track polyethylene anti-corrosion layer technical 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. The design, production and construction acceptance of the extruded polyethylene pipeline anti-corrosion layer shall comply with the provisions of this standard, and shall also comply with the relevant national mandatory standards.    
 
GB/T 23257-2009 Buried steel pipeline polyethylene anti-corrosion layer
 
This standard specifies the minimum technical requirements for the extrusion of polyethylene anti-corrosion coatings for buried steel pipelines. This standard is applicable to the design, production and construction acceptance of extruded polyethylene pipe anti-corrosion coating. Extrusion of the polyethylene anti-corrosion layer across the pipe can be referred to. Extruded polyethylene anti-corrosion layer can be divided into two types: normal temperature type (N) with long-term working maximum temperature not exceeding 50 °C and high temperature type (H) with long-term working maximum temperature not exceeding 70 °C.
 
Divided into ordinary grade enhanced grade anti-corrosion thickness 1.8-3.7um
