High Frequency Welded Pipe Mill HG127 for 40-127mm Pipes

High-frequency welded tube mill for low carbon steel and low alloy constructional steel production.

The HG127 High-Frequency Welded Pipe Production Line manufactures welded round pipes (Ф40～127mm diameter, 1.5～4.5mm wall thickness) and square pipes (40×40--100×100mm). Featuring precision roll pass design, it produces high-quality welded steel pipes with excellent machining quality and assembly precision.
