Product Description

High precision steel tube----Drawn over mandrel (DOM) steel tube

  Dom steel pipe is called precision steel pipe, and the main standards include GB3639 in China, ASTM A519 in the United States, and EN 10305 in Europe. It is a steel pipe with high dimensional accuracy and good inner and outer surface smoothness. After heat treatment, there is no oxide film on the inner and outer surfaces of the steel pipe. The steel pipe has no cracks when expanded or flattened, no deformation when cold bent, and can withstand high pressure. It can also undergo various complex deformations and mechanical deep processing treatments.
