The Function Of Plastic Coated Steel Pipe

The buried pipeline adopts the transmission line iron tower of plastic-coated steel pipe, which is composed of towers connected by tower pole devices. The tower is made of section steel. The steel surface of the tower rod and the inner and outer surfaces of the tower rod are hot-dipped with a modified polyethylene plastic layer. Plastic-coated steel pipes are steel pipes coated with red modified epoxy resin powder inside and outside. It is a new type of steel pipe made on the basis of steel pipes through sandblasting chemical pretreatment, preheating, internal and external coating, curing, and post-treatment.

Successfully solved the problems of burial, corrosion and scaling of plastic-coated steel pipes. There will be no pipe blockage and spray blockage, which improves the service life of the fire water supply pipe. Plastic-coated steel pipes mainly focus on the excellent mechanical properties of steel and the excellent chemical corrosion resistance of polymer materials. The product has excellent antistatic, high voltage and flame retardant properties, and can withstand harsh operating environments. Its ultra-corrosion resistance greatly improves the service life of the pipeline.

This kind of steel pipe has good pressure resistance and heat preservation performance. It mainly protects the wires, so there will be no leakage at all. So far, manufacturers of plastic-coated steel pipes are changing these advantages. The tube wall is relatively smooth without burrs. Suitable for spanning cables or wires during construction.

Plastic-coated steel pipes for fire-fighting buried pipelines have the advantages of smooth wall thickness, good drainage performance, low fluid resistance, and no scaling. Compared with other pipelines, they can greatly reduce losses. At the same time, the linear expansion coefficient of the large-diameter plastic-coated pipe is very small, which makes it very beneficial as a main pipe, and greatly overcomes the defects of other plastic pipes and ordinary pipes with a large linear expansion coefficient.

Plastic-coated steel pipe is an upgraded product of traditional steel-plastic pipe and galvanized pipe. It has comprehensive properties such as high strength, high elongation, good low temperature brittleness, low expansion coefficient, corrosion resistance, wear resistance, and low fluid resistance. It is a new type of water supply and drainage, anti-corrosion green large-diameter pipeline, and it is more and more widely used in domestic industries.
