High Quality Cold Rolled Seamless Steel Pipe Thick Wall Precision round Shape for Drill & Oil
Cold-rolled seamless pipe (GB3639-2000) is a cold-drawn or cold-rolled precision seamless steel pipe with high dimensional accuracy and good surface finish for mechanical structure and hydraulic equipment.
Steel Pipe Description
The main advantage of cold rolled steel pipe is that the section reduction rate is large, especially the wall reduction ability is strong. For carbon steel, the section reduction rate of a rolling can reach 80% to 83%, and alloy steel can reach 72% to 75%. The main disadvantage is the difficulty of tool replacement. In addition to the direct production of a part of the high precision cold rolled pipe, the cold rolling method is often used in combination with the cold drawing method for cold drawing. This can not only give full play to the wall reduction ability of cold rolling, but also make use of the advantages of easy replacement of cold drawing tools, which is conducive to improving productivity, expanding the production range of products and improving the surface quality of steel pipes.
