Stainless steel seamless pipe is a kind of long steel with a hollow section and no joints around it. The thicker the wall thickness of the product, the more economical and practical it is, the thinner the wall thickness, its processing costs will rise significantly.The process of the product determines its limited performance, the general precision of seamless steel pipe is low: the wall thickness is not uniform, the external brightness of the tube is low, the measurement cost is high, and the internal surface is not easy to remove pockmarks and black spots; Its detection and shaping must be handled offline. Therefore, it embodies its superiority in high pressure, high strength and mechanical structure materials.
