Product Description
20 Ton Self-Aligning Welding Rotator for Pressure Vessel & Tank Circumferential Welding
Product Overview
- This 20 Ton Self-Aligning Welding Rotator is heavy-duty equipment designed for circumferential welding of large tanks, pressure vessels and boiler drums.
- The self-aligning roller structure automatically adjusts support angles to fit various cylinder diameters without manual calibration. The built-in anti-offset mechanism stops axial sliding during rotation.
- Heavy-duty rigid frame and variable-frequency smooth rotation guarantee uniform welds. It can coordinate with longitudinal seam welders to finish full welding procedures for tank workpieces.
Core Advantages
- 20-ton heavy load bearing, thickened steel frame, stable operation for large pressure vessel processing.
- Self-aligning roller structure, automatically fit different pipe and tank diameters to save adjustment time.
- Polyurethane rollers avoid scratching workpiece surface, wear-resistant and long service life.
- Automatic anti-offset correction system to prevent tank sliding during high-load rotation.
- Frequency conversion stepless speed regulation, uniform rotating speed for consistent circular weld quality.
