Stainless seamless steel pipe is a kind of long steel with hollow section and no joints around. Stainless seamless steel pipe
Features of stainless seamless steel pipe:
First, 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; Secondly, the process of the product determines its limited performance. Generally, the precision of seamless steel pipe is low: uneven wall thickness, low brightness on the inner and outer surfaces of the pipe, high sizing cost, and pockmarks and black spots on the inner and outer surfaces are not easy to remove; Third, its detection and shaping must be handled offline. Therefore, it shows its advantages in high pressure, high strength and mechanical structure materials.
Type of stainless seamless steel pipe:
The connection and rolling methods include hot rolling, hot extrusion and cold drawing of stainless seamless steel pipes.
According to different metallographic structures of stainless steel, it can be divided into semi Ferritic and semi martensitic stainless seamless steel pipe, martensitic stainless steel pipe, austenitic ferritic stainless steel pipe, etc.
