Ф820-Ф3220mm Spiral Welded Pipe Mill
The Ф820-Ф3220mm Spiral Welded Pipe Mill is a heavy-duty SSAW production system designed to manufacture large-diameter steel pipes for oil, gas, and water transmission pipelines. The mill processes carbon steel and low-alloy steel coils with thicknesses up to 40 mm, forming them into helical seams using submerged arc welding. The system supports pipe diameters from 820 mm to 3220 mm and is configured for continuous operation under high-load conditions.
The mill conforms to API 5L and GB/T 9711 standards for line pipe applications. The spiral weld is produced using dual-wire submerged arc welding with flux recovery, achieving tensile strengths up to 570 MPa for API 5L X80-grade material. The forming rolls are hydraulically adjusted to maintain consistent helix angle within ±0.5 degrees, a critical factor for weld integrity under pressure. Typical pipe straightness tolerance is ±1 mm per meter, aligned with international pipeline construction norms.
This mill is targeted at industrial manufacturers and infrastructure contractors requiring export-ready pipe production capacity. Buyers typically invest in full-line systems for large-scale projects, with minimum orders limited to one complete unit. Packaging includes disassembled components in wooden crates with anti-corrosion treatment. Delivery is arranged under FOB Qingdao or CIF terms, with lead times ranging from 120 to 180 days depending on customization and component availability.
| Pipe Diameter Range | 820 mm to 3220 mm |
| Wall Thickness Range | 6 mm to 40 mm |
| Helix Angle Range | 10° to 30°, adjustable |
| Welding Method | Dual-wire submerged arc welding (SAW) with flux recovery |
| Material Compatibility | Carbon steel, low-alloy steel (API 5L Grade B to X80, GB/T 9711) |
| Max Production Speed | 1.8 m/min |
| Pipe Straightness Tolerance | ±1 mm per meter |
| Typical Weld Bead Width | 15 mm to 25 mm, standard for SAW pipe |
| Typical Flux Consumption | 0.8 kg to 1.2 kg per meter of weld, typical for dual-wire SAW |
| Power Requirement | 1200 kW, 380 V, 50 Hz, three-phase |

Sourcing Ф820-Ф3220mm Spiral Welded Pipe Mill from Cangzhou Zhongtuo Cold Roll Forming Machinery Ltd. - China Import Guide
Before ordering, verify the exact helix angle range, welding wire type, and flux specification supported by the mill. Request a material test report for a sample pipe produced on the line, including tensile strength, Charpy impact, and hydrostatic test results. Confirm whether the mill includes internal pipe cleaning or end beveling, as these are often optional add-ons.
Lead time for this system ranges from 120 to 180 days due to its complexity. Payment is typically structured as 30% advance, 40% before shipment, and 30% after successful factory acceptance test. Incoterms are commonly FOB Qingdao, but CIF may be available. Ensure the supplier provides a full packing list, export documentation, and English-language operating manuals.
For quality assurance, require a third-party pre-shipment inspection covering weld integrity, dimensional accuracy, and mechanical safety systems. Insist on visual inspection of all hydraulic lines, electrical enclosures, and lifting points. Confirm the inclusion of spare parts such as forming rolls, welding nozzles, and flux recovery units, as replacements are rarely stocked locally.
