Tianxianghao Highlights Automated Spiral Welded Pipe Production for Large Diameter Projects

CANGZHOU, China - EntSun -- Hebei Tianxianghao Metallurgical Equipment Manufacturing Co., Ltd. is strengthening its support for global pipe producers with a fully automatic spiral welded pipe production line engineered for efficient and consistent manufacturing. The system is designed for large-diameter and heavy-wall steel pipe production and can be configured around customer requirements for diameter, wall thickness, material, output, and inspection.

Tianxianghao also provides technical proposals and turnkey support for new production lines and plant upgrades. Where specified, configurations can be developed around applicable API project requirements.

Automated Production for Multiple Pipe Applications
The line supports the production of large-diameter and ultra-heavy-wall spiral welded pipes for oil and gas transmission, municipal water systems, foundation piling, structural construction, bridges, and marine infrastructure.

Automated coordination across feeding, forming, welding, cutting, and handling stages can help pipe producers improve process consistency, reduce manual intervention, and maintain stable output for demanding projects.

Flexible Forming and Double Sided Welding
By adjusting the forming angle of steel strips, the equipment can produce different pipe diameters while maintaining stable forming quality. This flexibility allows manufacturers to respond to changing project specifications without using a separate production concept for every pipe size. The integrated double-sided submerged arc welding system supports full weld penetration, strong seams, and consistent pipe performance under demanding service conditions.

Integrated Inspection and Quality Control
Tianxianghao can pair the pipe mill with ultrasonic testing equipment, hydrostatic testing machines, and industrial X-ray equipment for steel pipe inspection. Ensure online real-time pipe diameter monitoring system can accurately detect the pipe diameter of products and ensure the continuity and stability of pipe dimension.

This integrated production and inspection workflow helps manufacturers identify cracks, pores, incomplete fusion, and other weld discontinuities before shipment. Centralizing these systems can also simplify line planning and give project teams a clearer path from raw steel coil to inspected finished pipe.
