Equipment for inside weld bead control

1.Overview
Stainless steel welded pipe is superior to stainless steel seamless pipe in terms of material and mechanical properties, but the weld reinforcement of stainless steel welded pipe, especially the inside weld reinforcement control has always been a difficulty to be overcome by welding pipe industry. Though many manufactures tried inner blade or inner grinding device solution, the effect is not satisfied. This is the main impediment to further expend wider application in the welded pipe industry. Thus, in petroleum, chemical, nuclear power, boiler, food, pharmaceutical and other industries, stainless steel seamless pipe is still the mainly choice.

2. Our Equipment
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.

3. 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.
