The most direct difference between stainless steel seamless pipe and stainless steel decorative pipe is the appearance. The length of seamless pipe is basically inconsistent, while the length of stainless steel decorative pipe is basically fixed. The surface of stainless steel decorative tube is basically mirror-like, while stainless steel seamless tube is gray.

2. Differences in processes

Stainless steel seamless pipe is a kind of long steel with hollow section and no seam around it. The thicker the wall thickness of the product, the more economical and practical it is, and the thinner the wall thickness, the higher the processing cost. The technology of this product determines its limited performance. As the raw material of perforation, round tube blank is made by cold rolling, cold drawing or hot extrusion. There are no welding points on the pipe. Generally, seamless steel pipes have low precision: uneven wall thickness, low brightness on the inner and outer surfaces of the pipe, high length cost, and pits and black spots on the inner and outer surfaces are not easy to remove; Its detection and shaping must be done offline. Therefore, it shows its advantages in high pressure, high strength and mechanical structure materials.
