Stainless steel seamless pipe is a kind of long steel with hollow section and no seams around
1. Manufacturing process and flow of seamless steel pipe:
Smelting - ingot - rolling - sawing - peeling - piercing - annealing - pickling - dusting - cold drawing - cutting - pickling - warehousing
2. Features of seamless steel pipe:
It is easy to see from the above process flow: 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 its processing cost will be; Secondly, the process of this product determines its limitations. Generally, the precision of seamless steel pipe is low: the wall thickness is uneven, the brightness of the inner and outer surfaces of the pipe is low, the cost of sizing is high, and there are pits and black spots on the inner and outer surfaces that are difficult to remove; Third, its detection and shaping must be offline. Therefore, it shows its advantages in high pressure, high strength and mechanical structure materials.
