120-ton self-adjusting welding rotator is specially designed for petroleum pipeline welding.

The customer runs a dual production business of wind power towers and petrochemical pipelines, producing heavy-duty oil & gas and chemical pressure pipelines (3.2m–5.5m in diameter, 20–50mm in wall thickness, 60–100 tons in single-piece weight). These pipelines require ultra-high welding tightness, pressure resistance and stability, which demand precise and stable welding equipment. For this purpose, a 120-ton self-aligned welding rotator is deployed to achieve defect-free automatic welding for heavy pipeline production.

• Main self-aligned welding rotator unit
• Electric control cabinet
• Handheld remote controller
• Power connection cable
• Anchor bolts and fixing fasteners
• Operation manual

• Traditional roller supports rely on manual spacing adjustment for different specifications of wind power tower sections and petroleum pipelines, resulting in low processing efficiency and poor versatility for dual-type production.
• The weak load-bearing capacity causes equipment shaking and workpiece offset during the welding of heavy-duty wind power and petrochemical workpieces, leading to uneven welds and high defect rates.
• It delivers stable jitter-free and deviation-free low-speed rotation, perfectly satisfying the high-precision welding requirements for both wind power tower structural parts and oil & gas pipelines.
• Unstable rotating speed causes irregular welds on wind power structural parts and petroleum pipelines, failing to meet the strict stability and sealing standards for both industries.

Combining the customer’s dual production demands of wind power towers and petroleum pipeline fabrication, we customized a 120-ton self-aligned welding rotator suitable for both heavy-duty product processing scenarios.

• Adopting a reinforced all-steel structure, the equipment supports a rated 120-ton heavy load.
• The self-aligning roller structure automatically adapts to pipelines of different diameters without manual adjustment.
• The intelligent adaptive design enables a rapid production switch between wind power generation equipment and petrochemical pipeline welding. This significantly enhances the overall processing efficiency of the dual production lines.
• It maintains stable low-speed rotation without jitter or deviation, fully meeting high-precision welding standards for oil and gas pipelines.

• Improve production efficiency: The automatic positioning function eliminates repeated debugging for switching between wind power and petrochemical workpiece processing, greatly saves setup time and supports continuous batch production of dual product lines.
• Guarantee welding quality: Constant and stable rotation ensures uniform and smooth welds on wind power towers and heavy-duty pipelines, effectively reducing welding defects and improving the overall product qualification rate.
• Strong working stability: The equipment adapts to long-term heavy-load welding operation of both wind power equipment and petrochemical pipelines, perfectly matching diversified on-site working conditions.
• High customer recognition: The customer highly approves of the equipment’s stable operation and strong versatility for both wind power and petroleum pipeline welding. It complies with dual industry standards, cuts labor costs and defective rates, and ensures on-time project delivery, laying a solid foundation for long-term cooperation.

We provide targeted customized welding solutions for customers’ dual production of wind power equipment and heavy-duty petroleum pipelines, equipped with strict factory load testing, professional technical guidance and full-process after-sales service, to ensure stable and efficient operation of welding equipment for both production scenarios.
