Welded Steel Pipe Production
High-efficiency ERW tube mills for round pipes, square tubes, and structural steel sections. Suitable for carbon steel, galvanized steel, and industrial welded pipe manufacturing-delivering reliable, scalable production systems tailored to your industry needs.
What Is an ERW Tube Mill?
ERW stands for Electric Resistance Welding-a high-frequency welding technology widely used in steel pipe manufacturing. An ERW tube mill is an integrated production system designed to transform metal coils into high-quality welded pipes through a continuous, efficient process-making it one of the most popular choices for industrial pipe production worldwide.
How ERW Tube Mills Work
The core process follows a streamlined sequence, ensuring fast, consistent production:
Flat metal strips are first formed into the desired pipe shape, then welded using high-frequency electric resistance to create a strong, seamless-looking seam-no filler material required.
Why ERW Is Widely Used in Industry
- High Speed: Enables continuous mass production, significantly boosting output compared to traditional welding methods.
- Cost-Effective: Lower energy consumption and no filler material reduce operational costs.
- Stable Weld Quality: Consistent seam strength and precision meet strict industrial standards.
- Versatility: Capable of producing multiple pipe types and sizes for diverse applications.

Technical FAQ
What is an ERW tube mill?
An ERW (Electric Resistance Welding) tube mill is an integrated production system that uses high-frequency electric resistance to weld steel strips into seamless-looking pipes. It's a fast, cost-effective solution for mass-producing round, square, and rectangular welded pipes for industrial use.
How does HF welding work?
HF (High-Frequency) welding uses induction to heat the edges of the formed steel strip to a molten state. The heated edges are then pressed together to form a strong, continuous weld seam-no filler material is needed.
What is direct forming technology?
Direct forming is a specialized ERW process that shapes steel strips directly into square or rectangular tubes, eliminating the need to first form a round pipe. This reduces material waste and speeds up production.
How much does it cost?
Costs vary based on capacity and automation, typically ranging from $150,000 to $1.5 million+. We provide custom quotes based on your specific needs.
