Construction grade and anti-corrosion structure and method of polyethylene anti-corrosion tape

Anti-corrosion layer grade total thickness (mm) anti-corrosion layer structure

Ordinary grade ≥0.70 One layer of primer + one layer of inner belt + one layer of belt

Reinforced grade ≥ 1.40 One layer of primer + one layer of inner tape (overlap is 50~55% of tape width)

+ One layer of outer tape (overlap is 50~55% of tape width)

It is mainly used for oil and natural gas transmission; the outer surface of buried steel pipelines such as water supply and drainage and gas transportation in chemical industry and urban construction is anti-corrosion, which has the characteristics of convenient construction and no pollution. Polyethylene anti-corrosion tape has been widely used as an external anti-corrosion material on oil and gas steel pipelines since the 1960s. It has been used for more than 40 years. Due to its excellent anti-corrosion performance and convenient construction performance, it possesses in the pipeline anti-corrosion material system. Certain position. And because polyethylene anti-corrosion tape manufacturers continue to improve and improve the variety and quality of polyethylene tape, so that the application of polyethylene anti-corrosion tape continues to expand.
