　　Stainless steel seamless steel pipe is a kind of long steel with hollow section and no joint around it.

　　Characteristics of stainless steel seamless pipe:

　　Firstly, the thicker the wall thickness of the product, the more economical and practical it will be. The thinner the wall thickness, the higher the processing cost will be. Secondly, the process of the product determines its limited performance. Generally, the precision of seamless steel pipe is low; uneven wall thickness, low brightness of inner and outer surface of the ASTM A106 Sch40 Carbon Seamless Steel Pipes, high cost of sizing, and there are pits and black spots in the inner and outer surface; thirdly, seamless pipe is detection and removal are not easy. Shaping must be done offline. Therefore, seamless pipe embodies its superiority in high pressure, high strength and mechanical structure materials.

　　Seamless Pipe Technological Process

　　Pipe blank--inspection--peeling--inspection--heating--piercing--pickling--grinding--lubricating air-drying--welding head--cold drawing--solid solution treatment--pickling--pickling passivation--inspection--cold rolling--degreasing--cutting head--air-drying--internal polishing--inspection--marking--finished product packaging
