Coated steel pipe, also known as coated pipe, steel plastic composite pipe, or coated composite steel pipe, is a special type of steel pipe material. It adopts advanced coating technology for anti-corrosion treatment, uniformly covering the surface of the steel pipe with plastic coating, so that the steel pipe has excellent anti-corrosion and corrosion resistance performance during use. Therefore, coated steel pipes are widely used in transportation systems in industries such as chemical, construction, pharmaceutical, and power.

Advantages of coated steel pipes

Firstly, coated steel pipes have excellent corrosion resistance. Due to the presence of plastic coating, steel pipes are isolated from the external environment and are not easily corroded by factors such as oxidation and corrosion. Whether in humid marine environments or chemical plants with strong acid and alkali corrosiveness, coated steel pipes can maintain good performance, are not easy to rust or corrode, and greatly extend their service life. Secondly, coated steel pipes have good wear resistance. Plastic coating can effectively reduce the friction between steel pipes and external objects, and lower the degree of wear. In the transportation of granular materials, coal and other fields, coated steel pipes can reduce internal wear of pipelines, maintain pipeline smoothness, and improve transportation efficiency. In addition, coated steel pipes also have good pressure resistance. Plastic coating can increase the strength and stiffness of steel pipes, enabling them to withstand greater pressure. In situations where high-pressure liquids or gases are transported, coated steel pipes can maintain the stability of the pipeline and are less prone to safety accidents such as bursting and leakage. In addition, coated steel pipes also have good temperature resistance. Plastic coating can resist the erosion of high temperature environment and maintain the stability of steel pipes. In fields such as high-temperature furnaces and thermal power generation, coated steel pipes can withstand the test of high-temperature environments, are not easily deformed or melted, and ensure the normal operation of pipelines.
