20 Ton Self-Aligning Welding Turning Rolls for Carbon Steel Tank & Pipe Welding
Product Overview
This 20 ton self-aligning welding turning roll is designed for circumferential seam welding of carbon steel pipes, storage tanks and pressure vessels. The pivoting roller structure automatically adapts to different cylinder diameters, saving workpiece adjustment time. Equipped with PU anti-slip rollers and VFD stepless speed control, it works stably under full 20-ton load. CE certified, we support customization of anti-drift device, rail travelling base, special voltage and roller materials.
Main Features
Self-aligning adaptive structure: Pivoting roller design automatically fits various cylinder diameters without manual readjustment, greatly reduces setup time for batch production.
Heavy-duty stable frame & workpiece protection: Full welded steel frame ensures stable bearing capacity under 20-ton full load. Wear-resistant PU rollers are anti-slip and prevent scratches on workpiece surface.
Stable speed control & safety function: VFD stepless speed regulation for smooth rotation without jitter. Hand pendant control box with forward/reverse, speed adjustment and emergency stop.
Optional & customized functions: Optional anti-drift device to avoid axial drifting during long time welding; optional welding earth connector for high-current welding. Custom service for rail travelling, special voltage and roller material available.

On-site Matching Solution
The 20T self-aligning turning rolls can be flexibly matched with multiple welding equipment to build automatic welding workstation:
Matched with column & boom welding manipulator: Complete automatic circumferential & longitudinal seam welding for tank shell.
Matched with SAW/MIG welding power source: Suitable for thick plate carbon steel cylinder welding.
Matched with anti-drift device + grounding brush: Ideal for long continuous welding of large vessels, reduce workpiece axial displacement.
We can propose the whole workstation layout suggestion based on your workshop size and workpiece specifications.
Quality Assurance & Delivery
Full inspection: Every machine undergoes load test, rotation test and electrical inspection before shipment.
CE certification: All sets are CE compliant, documents provided to support EU customs clearance.
Packaging: Standard export plywood case or steel frame packing to protect machine during sea transportation.
Lead time: Standard model 15-25 working days; customized solution will confirm lead time separately.
After-sales: 12-month warranty, online technical guidance available anytime.
