Direct profile lines for square and rectangular tubes

ERW carbon steel tube mill with direct square forming unit

Nantong Reliantt stands out as a leading designer and manufacturer of fully automatic direct profile lines for square and rectangular steel tubes. 

This state-of-the-art ERW carbon steel tube mill employs a forming unit that enables the direct forming of square or rectangle sections. In contrast to the traditional approach, where the coil is initially formed into a circular shape and then later squared, this process brings unparalleled advantages in terms of flexibility, production capabilities, and efficiency.

The tube mill's automatic roller adjustment system, powered by servo motors or AC motors with absolute encoders on each stand, facilitates seamless adjustment of all rollers. This entire process is orchestrated by specialized software accessible from the control panel.

Thanks to the combination of these features, the direct profile lines by Nantong Reliantt offer several key advantages to manufacturers of square and rectangular tubes, such as:

- increased savings of raw material width by 2~4% for the same profile production; 
- adherence to customer requirements of multi-product small-batch production;
- reduced setup time and downtime, thanks to the possibility to modify profile dimensions without any roll changes;
- eliminate costs associated with forming rolls while increasing production capacity;
- ease of life for the operator and reduced maintenance.
