Stainless steel seamless pipe is a long strip of steel with a hollow section and no seams 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 its processing cost will be.
The process of this product determines its limited performance. Generally, seamless steel pipes have low precision: uneven wall thickness, low brightness inside and outside the tube, high cost of cutting to length, and pits and black spots on the inside and outside are not easy to remove; its detection and Shaping must be handled offline. Therefore, it embodies its superiority in terms of high pressure, high strength, and mechanical structural materials.
Stainless steel pipe is widely used in petroleum, chemical, medical, food, light industry, mechanical instrumentation and other industrial pipelines and mechanical structural components. In addition, when the bending and torsional strength are the same, the weight is light, so it is also widely used in the manufacture of mechanical parts and engineering structures. Also used as furniture and kitchenware.
