1. The main feature of a general seamless steel pipe is that it has no welding seam and can withstand greater pressure. The product can be a very rough cast or cold-drawn part.
2. Cold-drawn precision steel pipe is a product that has appeared in recent years. The main feature is that the inner hole and outer wall dimensions have strict tolerances and roughness.
Features of cold-drawn (rolled) precision steel pipe:
1. Smaller outer diameter
2. High precision can be produced in small batches
3. Cold-drawn (rolled) finished products have high precision and good surface quality
4. The cross-sectional area of the steel pipe is more complex
5. The steel pipe has better performance and the metal is denser.
