How steel pipe is made material, manufacture, making

They are produced by two distinct methods which result in either a welded or seamless pipe. In both methods, raw steel is first cast into a more workable starting form. It is then made into a pipe by stretching the steel out into a seamless tube or forcing the edges together and sealing them with a weld.

Difference between Seam Stainless Steel Pipe and Seamless

The manufacturing process of the seamless steel pipe is to punch out a hole in the stainless steel billet at a temperature of 2200 ° f, at which the tool steel is softened and spirally formed from the hole by pressing and drawing. So that the wall thickness of the pipe is not uniform and the eccentricity is high.

What is a seamless pipe? What are its functions? Quora

Seamless Pipe is formed by forcing molten metal through a round die with a plug in the center to form a long tube of continuous metal which is then cut into appropriate lengths; usually either 21 ft or 40 ft. although other lengths are available. Seamless Pipe is more uniform in consistency unlike Rolled and Welded Pipe that has been seam welded.
