I. Stainless steel hollow pipe manufacturing process
Seamless steel pipe is a hollow long steel, which is used as a pipeline for conveying fluids, such as oil, natural gas, water, gas, steam, etc. In addition, steel pipe has the characteristics of high bending resistance and good rigidity, so it is also widely used in the manufacture of mechanical parts and engineering structures.
Hot rolling is the main method of seamless pipe production. The main processes include perforation, extension, sizing and straightening. Perforation is use round billet to make hollow tube. The process is very important, the surface quality and wall thickness uniformity of hollow pipe will determine the quality of the finished product. Extension is used to make the wall thickness thinner, and get the size of finished product. The sizing process is finishing rolling process, the finished pipes will achieve final size and required precision on sizing mill. Straightening process is used to improve straightness of sealmess pipes.
