[0002] Because some stainless steel pipes will deform under external pressure during use, they need to be straightened by a straightening machine to facilitate their later reuse.

[0003] Straightening machines are equipment for straightening metal profiles, bars, pipes, wires, etc. Straightening machines use straightening rollers to squeeze bars and other materials to change their straightness. Generally, there are two rows of straightening rollers, with varying numbers. There are also two-roller straightening machines, which rely on the angle change of two rollers (concave in the middle, hyperbolic rollers) to straighten materials of different diameters. The main types include pressure straightening machines, balanced roller straightening machines, shoe roller straightening machines, rotary reverse bending straightening machines, etc.
