thick wall seamless steel tubing

Thick-walled steel pipe, the steel pipe whose outer diameter to wall thickness ratio is less than 20 is called thick-walled steel pipe. It is mainly used for petroleum geology drilling pipe, cracking pipe, boiler pipe, bearing pipe, automobile, tractor, aviation high-precision structural pipe and so on. The key to the quality of thick-walled steel pipe is the uniformity of wall thickness. If the wall thickness of thick-walled steel pipe is not controlled, it will directly affect the quality and use of steel pipe. Thick-walled steel pipe and large-caliber thick-walled steel pipe are generally used in various mechanical processing and thick-walled parts processing
