The characteristics of stainless steel coils in those years.

Stainless steel seamless steel pipe is a long steel material with a hollow section and no seams around it.
1. Seamless steel pipe manufacturing technology and process:
Smelting＞Steel ingot＞Rolling＞Sawing＞Peeling＞Perforation＞Annealing＞Pickling＞Ashing＞Cold drawing＞Head cutting＞Pickling＞Storage
2. Features of seamless steel pipe:
From the above process flow, we can easily see that: first, the thicker the wall thickness of the product, the more economical and practical it is; the thinner the wall thickness, its processing cost will increase significantly; secondly, the product The process of the product determines its limitations. Generally, seamless steel pipes have low precision: uneven wall thickness, low brightness of the inner and outer surfaces of the pipe, high cost of sizing, and pitting and black spots on the inner and outer surfaces that are difficult to remove; thirdly, its Detection and shaping must be processed offline. Therefore, it reflects its superiority in terms of high pressure, high strength, and mechanical structural materials.
