As industries evolve toward high-precision and energy-efficient manufacturing, Electric Resistance Welded (ERW) pipe mills have become the backbone of global steel pipe production.
An ERW pipe mill uses advanced high-frequency technology to produce durable and consistent pipes used in construction, energy transport, automotive systems, and mechanical fabrication.
Among China’s top equipment manufacturers, Shijiazhuang Faith Machinery Co., Ltd has distinguished itself through innovation, precision engineering, and customer-oriented solutions — becoming a reliable name in ERW pipe mill design and manufacturing.
An ERW pipe mill operates on the principle of high-frequency electrical resistance welding, which fuses the edges of a steel strip into a continuous tube without filler metal.
Uncoiling & Leveling: Steel coils are fed into the production line through a decoiler and straightener.
Edge Milling & Shearing: The strip edges are prepared to ensure perfect alignment before welding.
Forming: A series of forming rolls gradually shape the flat strip into a round tube.
Welding: A high-frequency current heats the strip edges, joining them under pressure to create a solid weld.
Bead Removing: Inner and outer weld beads are trimmed for a smooth surface finish.
Sizing & Straightening: Pipes are calibrated to precise diameters and wall thicknesses.
Cutting & Stacking: The final product is automatically cut and prepared for packaging.
This entire process is continuous and highly automated, resulting in excellent productivity, tight tolerances, and uniform weld strength.
Faith Machinery’s ERW pipe mills are built to deliver exceptional precision, reduced energy use, and enhanced flexibility.
Strong, Uniform Welds: High-frequency induction ensures metallurgical bonding with no filler material.
High Productivity: Continuous forming and cutting deliver line speeds up to 120 m/min.
Reduced Material Waste: Precise edge control minimizes scrap.
Energy Efficiency: Compact HF solid-state systems consume less power.
Low Maintenance Design: Modular structure and quick tool change system.
Digital Automation: PLC and servo-driven control ensures smooth coordination between forming, welding, and sizing.
