Dimension

Cold drawn precision steel pipe and the general difference between ordinary seamless steel pipe:

1, the general characteristics of ordinary seamless steel pipe is welded seam, can withstand greater pressure. The product can be very rough as cast or cold parts.

2, cold drawn precision steel pipe is the product in recent years, mainly the hole, the outer wall size has strict tolerances and roughness.

Cold drawn (rolled) precision steel pipe features:

1. smaller diameter.

2. High precision can be done small batch Health

3. Cold drawn (rolling) finished high precision, good surface quality.

4. Steel pipe cross-sectional area is more complex. 

5. Steel pipe performance is superior, the metal is relatively dense.
