Straightening machine is used to straight steel pipe and rod of black metal and non-ferrous metal. When pipe\rod is fed into the machine, the hyperbolic curved straightening rollers makes the straightened pipe\rod rotate forward, so that the pipe\rod continues bending and changing direction endlessly to realize straightening performance along centre line symmetry. Meanwhile, the process rectifies pipe\rod roundness. 

       Various kinds of straightening machines ranging OD10 ~325 mm are available.
