SY/T 0413-2002 Technical Standard for Polyethylene Anti-corrosion Coating of Buried Steel Pipeline Economic benefits, this standard is specially formulated. This standard applies to the design, production and construction acceptance of extruded polyethylene anti-corrosion coatings for buried steel pipelines. The extruded polyethylene anti-corrosion coating can be divided into normal temperature type (N) whose long-term working temperature does not exceed 50°C and high-temperature type (H) whose long-term working temperature does not exceed 70°C. The design, production and construction acceptance of extruded polyethylene anti-corrosion coatings for buried steel pipelines shall not only comply with the provisions of this standard, but also comply with the relevant current national mandatory standards.
GB/T 23257-2009 Polyethylene anti-corrosion coating for buried steel pipelines
This standard specifies the minimum technical requirements for extruded polyethylene anti-corrosion coatings for buried steel pipelines. This standard applies to the design, production and construction acceptance of extruded polyethylene anti-corrosion coatings for buried steel pipelines. Extruded polyethylene anti-corrosion layer across the pipeline can be implemented by reference. The extruded polyethylene anti-corrosion coating can be divided into normal temperature type (N) whose maximum long-term working temperature does not exceed 50°C and high-temperature type (H) whose long-term maximum working temperature does not exceed 70°C.
