Scaffold Steel Pipes Mills Factory

Shijiazhuang Faith Machinery Co.,Ltd’s Scaffold Steel Pipes Mills Factory delivers turnkey solutions for producing scaffold tubes used in construction, maintenance platforms, and temporary support structures. Scaffold pipes require consistent mechanical strength, precise dimensions, and reliable surface coatings to ensure safety and longevity on job sites.

Mill Design and Material Handling
The scaffold pipe line starts with a decoiler feeding black-annealed or galvanized strip (typically 48 mm to 60 mm wide and 1.2 mm to 2.5 mm thick) through a tension leveler that flattens and pre-stresses the material. Forming stands with robust bearing systems guide the strip into a circular section. An ERW induction welding head joins tube edges, creating a seam with controlled heat input to preserve mechanical properties.

Sizing, Testing, and Surface Treatment
Sizing stands refine the outer diameter to ±0.2 mm. Subsequent stretch forming units apply axial tension to relieve residual stresses and improve roundness—important for load-bearing applications. Inline ultrasonic testing inspects weld integrity, while a segmental hydrostatic station verifies seam tightness. For galvanized pipes, the line incorporates gentle handling with non-marking polyurethane rollers to protect the zinc coating.

Cutting and Coating Options
Flying cutoff saws deliver scaffold pipe lengths—commonly 3 m to 6 m—with end squareness within ±1 mm. Post-cut ends may pass through chamfering tools to remove burrs. An optional inline epoxy or powder coating system can apply a protective layer for enhanced corrosion resistance in aggressive environments.

Automation and Operational Control
A distributed PLC system controls decoiler tension, roll stand servo positions, welding power, and downstream modules. The HMI interface allows selection of pipe sizes, coating options, and test parameters. Real-time data on line speed, weld current, test pressures, and coating thickness are logged for full production traceability.

Factory Support and Maintenance
Shijiazhuang Faith’s factory service includes turnkey installation, civil works coordination, and utilities commissioning. Operator certification covers safety protocols, weld inspection, and routine maintenance such as roll alignment checks, welding coil inspections, and sensor calibrations. Spare parts kits—including induction coil modules, shear blades, and bearing sets—are provided to minimize downtime. Remote diagnostics and parameter tuning ensure the scaffold pipe mill operates continuously to meet the demands of large-scale construction projects.
