What are the factors affecting the straightness of seamless steel pipes? The straightness of seamless steel pipes has a great impact on pipes for precision machinery and hydraulic cylinders. High straightness accuracy can improve customers' later processing efficiency and reduce production costs.

1. Backward straightening equipment
The straightening equipment is backward and the straightening accuracy is poor. The straightness of seamless steel pipes has not been greatly improved after they come out, and they can only be visually inspected without bending. Such seamless steel pipe straightness requirements cannot meet the requirements of the precision processing industry. For example, hydraulic cylinders have high requirements for the straightness of steel pipes, and the consistency of the inner hole needs to be maintained. If the straightening equipment is backward, it is far from meeting the requirements. Rencheng has advanced straightening equipment that can control the accuracy of the straightness of seamless steel pipes to 0.5mm/m, meeting the production requirements of hydraulic cylinders.

2. Production process of seamless steel pipes
Two production processes are selected during the production process of seamless steel pipes, namely, fine rolling and cold drawing. Generally speaking, the straightness of seamless steel pipes after fine rolling is better than that after cold drawing, because fine rolling is rolling, which will not produce much elastic force on seamless steel pipes. However, during the cold drawing process, the seamless steel pipe is stretched as a whole and has great elastic force. When the seamless steel pipe leaves the drawing machine, plastic deformation will occur.

The above is the answer to the factors affecting the straightness of seamless steel pipes. Straightness is an important indicator for precision pipes. The better the straightness, the better the yield rate of later processing. For example, hydraulic cylinders, mechanical parts, and other fields have high requirements for the straightness of seamless steel pipes. Rencheng Steel Pipe can meet your high requirements for the straightness of seamless steel pipes, and the best straightness is 0.5mm/m
