Stainless steel seamless steel pipe is a long steel with a hollow cross section and no seams around it.
1. Manufacturing process and process of seamless steel pipe:
Smelting> steel ingots> rolling steel> saw cutting> peeling> perforation> annealing> pickling> ashing> cold drawing> cutting head> picking> into the warehouse
2. Features of seamless steel pipe:
It is not difficult to see from the above process: First, the thicker the wall thickness of the product, the more economical and practical it is. The thinner the wall thickness, the higher its processing cost. Secondly, the The technology of the product determines its limited performance. Generally, the seamless steel pipe has low accuracy: uneven wall thickness, low brightness on the inside and outside of the tube, high fixed-length cost, and pits and spots on the inside and outside. Detection and shaping must be done offline. Therefore, it shows its superiority in terms of high pressure, high strength, and mechanical structural materials.
