Plastic-coated steel pipes, also known as plastic-coated pipes, steel-plastic composite pipes, and plastic-coated composite steel pipes, are based on steel pipes. A layer of plastic anti-corrosion layer or plastic anti-corrosion layer is fused to the inner surface of the steel pipe (bottom pipe) thr

The high-frequency welding process of straight seam steel pipes is completed in high-frequency welded pipe units. High-frequency welded pipe units usually consist of roll forming, high-frequency welding, extrusion, cooling, sizing, flying saw cutting, and other components. The front end of the unit

(1) Dust, oil, oxide scale, etc. on the anti-corrosion coated steel pipe surface must be removed before coating. Reach Sa 2.5 level to ensure painting quality. It is strictly prohibited to bring in water during construction.(2) The construction proportioning method is: open the mouth of component A,

Corrosion in steel pipes occurs because metals are sometimes susceptible to chemical reactions that weaken them. Once the metal is weakened, it becomes susceptible to rust and can form cracks and holes, which is a big problem. Therefore, it is vital that steel pipes are protected against corrosion,
