The newly produced 45# seamless pipe has a large curvature and needs to be straightened. Let's take a look at the straightening process of 45# seamless pipe.

The basic principle of 45# seamless pipe straightening is to make the seamless pipe have elastic-plastic twists and turns, from large twists to small twists and turns, so it is necessary to have repeated twists and turns in the straightening machine. However, the degree of twists and turns of 45# seamless pipe is mainly determined by the adjustment of straightener.

The twists of 45# seamless pipe is caused by improper adjustment of rolling mill, residual stress during rolling and unequal cooling along pipe section and length. Therefore, it is impossible to get straight pipes directly from the rolling mill. Only through cold straightening can the pipe's tortuosity achieve satisfactory results.

After straightening, 45# seamless pipe finishes the whole production process, can be sold in the market, and can play its largest role in the use process.
