Stainless steel seamless pipe is a kind of long steel with hollow section and no seams around. The thicker the wall thickness of the product is, the more economical and practical it is. The thinner the wall thickness is, the higher the processing cost will be. The process of this product determines its limited performance. Generally, the seamless steel pipe has low precision: uneven wall thickness, low brightness of the inner and outer surfaces of the pipe, high cost of sizing, and there are pits and black spots on the inner and outer surfaces that are difficult to remove; Its detection and shaping must be offline. Therefore, it shows its advantages in terms of high pressure, strength and mechanical structure materials.
