Seamless steel pipe VS Precision steel pipe:
1. The main feature of seamless steel pipe is that it has no welds and can withstand greater pressure. Products can be very rough as-cast or cold drawn.
2. Cold-drawn precision steel pipes are products that have appeared in recent years, mainly because the inner hole and outer wall dimensions have strict tolerances and roughness.
The precision seamless steel pipe is made by the cold rolling process of the precision cold rolling mill, and the cold drawn seamless steel pipe is made by the cold drawing method. Generally speaking, the precision, finish and size of the cold rolled pipe are better than those of the cold drawn Much better. Precision seamless steel pipe is used in automobiles, hydraulic parts, machining, mechanical parts and other users who have high requirements on the precision and finish of steel pipes. Because precision seamless steel pipes have high precision, no oxide layer, small dimensional tolerance and good finish, so Many machining users choose precision seamless steel pipes in order to save labor, material and time losses.
