The welding seam inside Leveling machines is composed of leveling frame, hydraulic and pneumatic systems, PLC fully automatic controlled electro-hydraulic pneumatic system, also including molds and rolling fluid circulation device.

 Technical features
The principle of welding seam inside leveling machine is employing a built-in mandrel and roller,  reciprocating rolling the stainless steel welded pipe automatically, by controlling the rolling strength and pass to level both inner and outer side of the welding seam , completely control the weld reinforcement to be flushed with the base material. Generally speaking, the technology is to achieve the seamless stainless steel welded pipe effect.
