Seamless Stainless Steel Pipe
The seamless stainless steel pipe is a kind of long bar shaped steel with hollow section and no seam around.
Features
1. The seamless stainless steel pipe shows more excellent economical efficiency and practicability with the increase in wall thickness. The production cost increases substantially when the wall thickness is very small.
2. The seamless stainless steel pipe is bound to have limitations due to the production process. It often has low accuracy, uneven wall thickness, and low surface brightness. Also, there are black spots on the inner and outer surfaces, and these spots are difficult to remove. The sizing cost is high as well.
3. The detection and shaping of seamless stainless steel tube must be processed off-line. Hence, the seamless stainless steel pipe shows superiority in high pressure, high strength and mechanical structure.
