The HG76 ERW Tube Mill is a high-frequency welded pipe production line designed for manufacturing round steel pipes with diameters from 25 mm to 76 mm, as well as square and rectangular steel tubes. With a production speed of 20–100 m/min and a 300 kW high-frequency welding system, the HG76 tube mill supports continuous production of welded pipes for construction, furniture, mechanical structures, and industrial applications.
Main Features of ERW76 ERW Pipe Making Machine
High Frequency Welding: Delivers smooth, uniform weld seams with high precision and strength.
Quick Roll Change System: Minimizes downtime and improves production flexibility.
PLC & HMI Automation: Centralized control with digital adjustment of speed, cutting length, and welding parameters.
Energy Efficient Design: Optimized electrical system and low-resistance transmission reduce power consumption.
Versatile Applications: Suitable for round, square, and rectangular pipes, with optional forming modules.
What Pipes Can the HG76 ERW Tube Mill Produce?
The HG76 ERW tube mill supports the production of round, square, and rectangular welded steel tubes within its forming and sizing range. It is suitable for steel pipe manufacturers supplying multiple industrial markets.
● Round Steel Pipes
With a diameter range of 25–76 mm, the HG76 tube mill is suitable for producing round welded steel pipes used in structural frameworks, mechanical components, general fabrication, and industrial piping applications.
● Square Steel Tubes
The production line can manufacture square tubes from 15 × 15 mm to 60 × 60 mm. These tubes are widely used for steel furniture, building frameworks, metal structures, and equipment frames.
● Rectangular Steel Tubes
The HG76 supports rectangular tube sizes from 10 × 20 mm to 40 × 80 mm, making it suitable for producing steel profiles used in metal fabrication, structural supports, shelving systems, and general engineering applications.
The required roll tooling and sizing configuration are selected according to the finished tube dimensions and wall thickness.
FAQ – Common Questions About ERW Pipe Making Machine
Q:What is the difference between ERW and SAW pipe production?
A:ERW (Electric Resistance Welding) uses high frequency current to heat and join steel edges, ideal for smaller-diameter pipes with smooth seams. SAW uses submerged arc welding for larger pipes.
Q:Can the HG76 ERW line produce square or rectangular pipes?
A:Yes. With additional forming and sizing rolls, it can produce various shapes such as round, square, and rectangular tubes.
Q:Do you provide installation and training services?
A:Yes, we provide complete installation, commissioning, and operator training for all ERW tube mill lines.
