タイトルまたは説明

Plastic coated steel pipe has both the high strength of steel pipe and the chemical corrosion resistance of engineering plastics, and the thickness of its surface coating reaches 0.3~1mm. When transporting various fluids, the resistance coefficient is small, and there is no bacteria and mold; It has good anti scaling ability. In general, compared with steel pipes with the same diameter, the fluid delivery volume increases by 7%~*2%, and the transmission power consumption decreases by *5%; The service life can reach *****0 years, so it can be said that the plastic coated steel pipe is a new type of pipe with high efficiency, energy conservation, environmental protection and corrosion prevention. Plastic coated steel pipes have been widely used in various industries in industrialized countries, such as oil and gas pipelines, water supply and drainage pipelines; *- Some countries have also adopted plastic coated steel pipes for submarine manganese ore suction pipes and pipes for nuclear power plants. The production of coated steel pipes in China has made innovations and improvements on the basis of introduction. In recent years, the quality of plastic powder coatings in China has made great progress. Several commonly used plastic powders, such as epoxy resin (EP) and polyethylene (PE), have become increasingly mature in domestic formulations. Some reliable data have been obtained in application. The domestic formulations have become increasingly mature. Some reliable data have been obtained in application, and their quality has reached the international advanced level
