Mar 18, 2021 · Seamless pipe:The manufacturing process of seamless steel pipe is to punch a hole in a stainless steel billet at a temperature of 2200°f. At this high temperature, the tool steel becomes soft and spirals out of the hole after punching and drawing. Shaped out. In this way, the wall thickness of the pipeline is uneven and the eccentricity is high. seamless steel pipe - Shandong Huali Hydraulic Machinery China seamless steel pipe catalog of Best Service DIN2391 St52 Cold Drawing Precision Pipe, High Quality ASTM A106 Gr.
