What is Polished steel pipe?

Polished steel pipe is a kind of pipe, which has good corrosion resistance, heat resistance, low temperature strength and mechanical properties, good hot workability such as stamping and bending, no heat treatment hardening phenomenon (non magnetic), molybdenum content and low carbon content. Its resistance to spot corrosion in marine and chemical industrial environment is significantly better than 304 stainless steel (316L low carbon, 316N nitrogen high strength, 316 stainless steel high sulfur content, easy to cut stainless steel)
Polished steel pipe is divided into electrolytic polishing and mechanical polishing of stainless steel pipe.
The polishing process of stainless steel pipe is actually the process of cutting the pipe surface. The pipe surface is cut by using the friction between the polished material, the polished instrument and the pipe surface to obtain the corresponding polished surface. The light of stainless steel pipe can be divided into internal and external light. The existing external light is to use the combination of hemp wheel or abrasive wheel with different coarse grain size to light and obtain the corresponding polished surface.
The inner part is to cut the inner surface of the pipe by reciprocating or rotating movement of the plastic grinding head (covered with emery cloth) inside the pipe. The light of stainless steel pipe can be divided into wet and dry. Check whether the polishing tube is not straight. The polishing tube bends in the same direction (close to the weld bead), which is the problem of pipe making, that is, the height of the weld bead or the thickness of the material. The bending is not uniform, which is due to polishing and linear adjustment problems.
