5Ton/10Ton/20Ton Tank Welding Roller, Adjustable Roller Spacing Welding Rotator
Adjustable Welding Rotator 5T 10T 20T
Adjustable welding turning rolls are designed for circumferential welding of cylindrical workpieces, including water tanks, boilers, small pressure vessels, pipes and stainless steel barrels. The roller center distance can be manually adjusted to adapt different cylinder diameters, widely used in metal fabrication workshops.


Main Features
- Adjustable Roller Spacing: Roller base with reserved holes or screw adjustment, easy to change roller distance to fit various tank OD. Suitable for mixed batch production.
- VFD Stepless Rotation Speed: Stable variable frequency drive, smooth rotation, no shaking. Match SAW, MIG/TIG automatic girth welding.
- Optional Roller Material: PU roller: Protect thin stainless plate surface, no scratch. Steel roller: For heavy carbon steel thick wall tank, high wear resistance.
- Simple & Safe Operation: Equipped with control box and hand pendant, forward/reverse, speed adjustment, emergency stop function.
- Robust Welded Frame: Heavy welded steel base, strong load bearing, low failure rate for long time continuous working.
Application
Pressure vessel, industrial boiler, water storage tank, chemical cylinder, pipe fabrication, steel structure workshop.
We also supply welding positioner, longitudinal seam welding machine, fiber laser cutter and plasma cutting machine. All machines are CE certified. For Russian market, we can support TR CU / EAC certification application.

FAQ
Q1: What is the difference between adjustable rotator and self-aligning rotator?
A: Adjustable type needs manual adjustment of roller distance. Lower cost, good for fixed batch production. Self-aligning model automatically adapts cylinder diameter with no manual adjustment.
Q2: Can this rotator work with submerged arc welding system?
A: Yes. Stable low-speed rotation matches SAW girth welding. We can make linkage function upon request.
Q3: Can you support TR CU EAC certificate for Russia market?
A: Yes, our welding equipment can apply TR CU certification to meet EAEU customs clearance.
Q4: What's included in one set?
A: 1 driving roller +1 idler roller set, electric control cabinet, wired remote controller.
