The manufacturer of Seamless steel pipe for machining tells you that making seamless steel pipes that have been processed into products with less tortuosity has to rely on mechanical straightening machines to finish. Therefore, in order to eliminate the twists and turns of seamless steel pipes, all seamless steel pipes need to be cold straightened.

The manufacturer of Seamless steel pipe for machining tells you that the zigzag of seamless steel pipe is caused by improper adjustment of the rolling mill, residual residual stress during rolling, and unequal cooling along the section and length of the pipe. Therefore, it is impossible to obtain a very straight tube directly from the rolling mill, as long as the tortuosity of the tube is cold-straightened to meet the technical requirements.
The manufacturer of Seamless steel pipe for machining tells you that the basic principle of straightening is to make seamless steel pipes undergo elasto-plastic twists, from large twists to small twists, so steel pipes must be repeatedly twisted in the straightening machine. The degree of repeated twists and turns of the steel pipe is mainly determined by the adjustment of the straightening machine.
The manufacturer of Seamless steel pipe for machining tells you that there are many factors that affect the quality of straightening, such as the tortuosity of the original pipe, the size of the steel pipe, the type of material straightening model, and the adjustment of parameters.
