pipe rollers for welding

Anti - drift type High Precision Pipe Welding Rotator for narrow gap vessel adjustment

Quick Detail

• Applicable for narrow gap vessel welding on thick-wall cylinder, or it is necessary to prevent axial drift of work-piece during welding. 
• Its adjustment is adopted with roller up-lift type;
• Electric system is composed of PLC, A.C. Inverter, HMI and displacement sensor.
• The displacement sensor is made by NOVO of Germany;
• The main control applies the PLC and A/D converter unit of MITSUBISHI FX2N.

1. Introduction

This kind of turning-rolls or pipe welding rotators are applicable for narrow gap vessel welding on thick-wall cylinder, or it is necessary to prevent axial drift of work-piece during welding. Its adjustment is adopted with roller up-lift type, which is advanced in structure, complete in function, easy in operation and reliable in performance. So it is ideal equipment for improving welding quality and realizing welding automation.

We also tailor made this type of pipe welding rotator upon your requirements. Please communicate with us for more details.
