What is Tube Mill Line?
A Tube Mill Line is a steel pipe manufacturing system that forms steel strips into tubes and welds them using high-frequency induction welding technology.
It is widely used in the production of ERW steel pipes for construction, oil and gas, automotive, and structural applications.
Equipment Composition:
Forming and sizing mill
Cooling system
Flying cold saw (burr-free cutting)
Production Range:
High-precision processing for round, square, rectangular, oval, and complex special-shaped pipes. Expertly handles materials such as carbon steel, galvanized steel, and API high-strength steel pipes.
Core Technologies:
Advanced PLC automation control, servo motor drive, high-frequency welding, and high-speed cutting technology to ensure efficient, stable, and 24/7 high-output operation.

The following FAQs explain key information about Tube Mill Line equipment, performance, and operation.
A: Our high-speed ERW tube mill lines can achieve stable production speeds of up to 130 m/min, depending on the pipe diameter and wall thickness, providing maximum output efficiency for global manufacturers.
A: Yes. With our fast changeover design, you can switch between different pipe shapes and mold sizes efficiently on the same steel pipe machine, minimizing downtime and maximizing utilization.
