There are three main deformation processes throughout hot rolled seamless steel pipe production methods.


1. Perforating.
Perforation methods are common rotary piercing and pressure perfortion. In addition, we can use centrifugal casting, continuous casting with electroslag re-melting and other methods to obtain a hollow shell and to eliminate the perforation step.
2. Rolling.
On the extension machine, the pipe billit will roll thin capillary and become close to extending the original pipe wall thickness. The common type of rolling methods including continuous rolling, rolling cycle, automatic rolling tube, top tube, three roll rolllin, two roll rolling etc. 
 3. Finishing.
The main process for pipe finishing are sizing and reducing. The goal is to achieve improved accuracy of the pipe thickness, improve the surface quality, improve pipe roundness and expand the product specifications.
