2025-01-15 First, the difference between cold-drawn precision steel pipe and general seamless steel pipe1. 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 p
