Core Advantages
Automatic self-centering roller design, greatly shorten equipment adjustment time for multi-specification workpieces.
Dual-motor synchronous driving system, stable operation under 20 ton heavy load without slipping.
PU anti-scratch rollers, effectively avoid surface damage to stainless steel pressure vessels.
Application Scope
✅ Medium & Large Pressure Vessel Production
Suitable for girth welding of medium and large tanks in pressure vessel manufacturing factories.
✅ Chemical Equipment Fabrication
Used for rotary welding of chemical storage tanks and reaction vessels.
✅ Boiler Component Processing
Ideal for fabrication of boiler barrels, headers and other cylindrical boiler parts.
✅ Metallurgy & Pipeline Manufacturing
Fit for processing all types of cylindrical structural workpieces in metallurgy and pipeline industry.
Working Principle
1.Consist of driving unit and driven unit to jointly support cylindrical pressure vessel workpieces.
2.Roller support angle automatically swings to realize self-centering according to workpiece outer diameter.
3.Frequency converter controls driving motor to achieve stable constant-speed rotation.
4.Realize continuous circumferential welding by rotating pressure vessel instead of moving welding torch.
Quality Assurance
- Wireless remote control pendant for convenient on-site operation.
- Signal linkage interface to connect welding manipulator and welding machine.
- High temperature resistant cast steel rollers for high-temperature workpiece welding.
- Extended base frame to adapt longer cylindrical pressure vessels.
