Hot Expanded Steel Pipes
Hot expanded is a process that uses oblique rolling or drawing to expand the diameter of the steel pipe. It is usually used to manufacture large diameter steel pipes or non-standard diameter steel pipes. We can provide hot expanded steel pipes that the diameter range is 325mm-1020mm. The diameter of hot expanded steel pipes also can be customized according to clients’ requirements. Welcome to your purchase.
Description
Introduction of Hot Expanded steel pipes
The principle of hot expanded steel pipes is to utilize the thermoplastic and plastic deformation characteristics of metal materials. When steel pipes are heated, their grain structure undergo changes and their plasticity will increase, therefore when mechanical force is applied to the steel pipe, it undergoes plastic deformation. Finally realize the changes in the size and shape of steel pipes. Hot expanded process has the characteristics of low costs and high production efficiency. In additions, due to its flexibility in size selection, hot expanded process has become an important production process for manufacturing of large diameter steel pipes and special diameter steel pipes.
