400 Ton Welding Turning Rolls for Large Pipeline Fabrication | Saudi Arabia

A large petrochemical pipeline manufacturer in Saudi Arabia needed heavy-duty turning rolls for prefabrication of thick-wall large-diameter pipeline segments. The workshop undertakes oil & gas pipeline fabrication for local energy projects. The original equipment could not support ultra-heavy pipe rotation, resulting in low welding efficiency and poor circular seam quality. They selected our 400 Ton adjustable welding turning rolls as the core rotating equipment for their pipeline workshop.

1. Max loading capacity: 400 tons for single pipe segment
2. Workpiece: Large diameter thick-wall carbon steel pipeline, OD up to 4200 mm
3. Continuous 24h batch production for circumferential seam welding
4. Stable low-speed rotation, low runout to guarantee uniform weld bead
5. Adapt to harsh high-temperature workshop environment in Arabia
6. CE certification, 380V/50Hz power system matching local standard

We supplied heavy-duty adjustable 400t turning rolls with reinforced welded frame and forged roller wheels.

• Adjustable roller position to fit different pipe outer diameters
• High-torque variable frequency drive system, rotation speed 0.1–1 m/min stepless adjustable
• Anti-high temperature and anti-slip roller surface, resist welding spatter
• Split combined structure, convenient on-site assembly inside customer’s workshop
• Localized electrical configuration, with overload protection and emergency stop function
• Full load running test completed before shipment; installation guidance and operator training provided on site.

• Successfully support 400-ton heavy pipeline rotation for circumferential welding
• Welding rework rate greatly reduced; production capacity increased by over 40%
• Stable continuous operation under local high-temperature workshop conditions
• Help client pass third-party inspection for energy pipeline fabrication
• Customer extends cooperation for follow-up batches of pipe fabrication projects.

“The 400 Ton adjustable welding turning rolls operate smoothly even under our maximum 400t pipe load. Workpiece runout is well controlled, our girth weld quality meets the strict oil & gas project standards. The equipment withstands our high-temperature workshop environment reliably for round-the-clock production. Self-align function saves plenty of pipe alignment time and cuts our labor cost. Your after-sales technical support and training were professional and timely. We will keep your machinery as our preferred supplier for upcoming large pipeline projects.”
