In addition, composite steel pipes can effectively prevent medium leakage and ensure the stability and efficiency of industrial production. Secondly, composite steel pipes also play an important role in industrial construction and can be used for building support structures, process equipment and pipeline systems. The use of composite steel pipes can simplify engineering construction, improve construction efficiency and reduce engineering costs. Finally, composite steel pipes can also provide better environmental protection solutions for industrial enterprises. It is corrosion-resistant and wear-resistant, can reduce the generation of waste, and can be recycled and reused, effectively reducing environmental pollution.

[0005] Plastic coated steel pipe, also known as plastic coated pipe, steel plastic composite pipe, plastic coated composite steel pipe, is a steel plastic composite steel pipe with steel pipe as the base, a plastic anti-corrosion layer is welded on the inner surface of the steel pipe (bottom pipe) or on the inner and outer surfaces through spraying, rolling, dipping and suction processes. Plastic coated steel pipe has excellent corrosion resistance and relatively small friction resistance. Epoxy resin coated steel pipe is suitable for the transportation of water supply and drainage, seawater, warm water, oil, gas and other media, and polyvinyl chloride coated steel pipe is suitable for the transportation of drainage, seawater, oil, gas and other media.

[0006] However, the existing plastic-coated composite steel pipe is one of the most advanced anti-corrosion pipeline products in China, and the market is booming.
