Seamless steel pipe because of its different manufacturing process, is divided into hot-rolled (extruded) seamless steel pipe and cold drawn (rolling) seamless steel pipe two. Cold drawn seamless steel pipe is the product in recent years, mainly the hole, the outer wall size has strict tolerances and roughness.

1. smaller diameter. 2. High precision can be done small batch Health 3. Cold drawn (rolling) seamless steel pipe with high accuracy, good surface quality 4. Cold drawn seamless steel pipe cross section is more complex. 5. Cold-drawn seamless steel pipe performance is superior, seamless steel pipe more dense. 6. Cold-drawn seamless steel pipe partial wall to reduce the situation, the internal and external diameter can be controlled according to customer requirements within 10 silk
