Product Description
Long Axis Welding Turning Rolls For 12m Workpiece | Multi‑support Roller Welding Rotator
Product Overview
This long‑shaft welding turning rolls is specially developed for extra‑long cylindrical workpieces up to 12 meters. Adopting multi‑group supporting roller layout, it effectively solves workpiece sagging and deformation during rotation. Equipped with VFD stepless speed regulation, it keeps uniform rotary motion for long‑pipe, long‑cylinder girth welding. Widely used in long pipeline, tower barrel, large‑length metal cylinder manufacturing.
Core Functional Highlights
- Multi‑support roller layout, specially designed for 12‑meter extra‑long cylindrical workpieces, reduces workpiece bending‑sagging risk
- VFD stepless speed control, stable rotating performance for consistent circumferential welding seam quality
- High‑strength polyurethane rollers, great friction performance, prevent slipping and protect workpiece outer surface
- Integral heavy‑duty frame with stress‑relief annealing treatment, strong rigidity for long‑time heavy‑load operation
- Hand‑held pendant controller, convenient on‑site start‑stop and real‑time speed adjustment
- Flexible expandable structure, extra roller groups can be added for longer workpieces; supports multiple optional upgrades

Frequently Asked Questions
Q1: Can this turning rolls prevent 12‑meter long workpiece from sagging?
A1: Yes. Multi‑support roller distribution disperses pressure effectively and reduces bending sag during rotating welding.
Q2: Can we add more roller groups for workpieces longer than 12m?
A2: Yes, auxiliary roller groups can be customized according to actual workpiece length.
Q3: Is steel roller available for high‑temperature welding condition?
A3: Solid steel roller is optional, suitable for high‑heat welding scenario.
Q4: Can voltage be customized for overseas site?
A4: Voltage and frequency can be adjusted to match local power supply.
Q5: Can it cooperate with automatic welding manipulator?
A5: Synchronous linkage assembly is optional to realize automatic girth welding.
