1. The main feature of ordinary seamless steel pipes is that they have no welded seams and can withstand greater pressure. The product can be very rough cast or cold drawn parts. 2. Cold-drawn precision steel pipes are products that have emerged in recent years, mainly because the inner hole and outer wall dimensions have strict tolerances and roughness. Features of cold drawn (rolled) precision steel tubes: 1. Smaller outer diameter. 2. High precision can be produced in small batches. 3. The cold drawn (rolled) finished product has high precision and good surface quality. . 4. The horizontal area of steel pipe is more complicated. 5. The performance of the steel pipe is superior, and the metal is denser.
