(b) Background of the invention Seamless steel pipes are generally used for gas pipes, general purpose steel pipes, cancer use,
Used for steel pipes for oil wells and water supplies. In terms of manufacturing method, steel pipes can be divided into seamless steel pipes and forged welded steel pipes, depending on the presence or absence of seams. Seamless steel pipe (seamless 5
A steel tube (teel tube) is made by heating a steel ingot or a steel bar for pipe material, drilling a hole called a blank hole using a drilling machine, and rolling it with several people inserting a hard mandrel. Two methods are used in the finishing process: hot finishing and cold finishing.

For hot-finished steel pipes, finishing work is performed on the pipe under heating conditions.
Cold-finished steel pipes are made from raw pipes that are cooled and then finished on a draw bench to increase or decrease the diameter and reduce the wall thickness. Compared to the hot finishing method, which involves high temperatures and difficulty in measuring dimensions, cold finishing allows for the production of products with high precision in dimensions, but on the other hand, it is of higher quality and more expensive.
