The Coated Steel Pipe is widely used in various fields in China, especially in the construction of fire pipe and gas pipeline and mine pipeline. So, how can the buyer choose high-quality coated steel pipe from the market?
The coated steel pipe is made of welded steel tube and coated with epoxy resin (EP). After a series of complicated process, the steel tube is first used in the selection of the steel tube. Because the steel tube determines the pressure of the whole product, the surface of the steel pipe should be smooth and free of bubbles.
Second, the coating is homogeneous in degree, thickness and adhesion. If the adhesion of steel tube and coating layer is poor, it is easy to get rid of plastic, and the follow-up is more troublesome.
