The largest mills in our range. Pipeline and petrochemical pipe up to Ø508 mm and 18 mm wall — supplied with the heavy roll stands, the long cooling and the handling equipment that go with a line of that size.

How to choose the right model
Start from the tube you already sell, not from the machine. The HG355, HG426 & HG508 Large Diameter Line covers Ø165 – Ø508 mm at 4 – 14 wall, and it sits between HG355 below and HG508 above. If your product range spans two models, quote the larger one — a mill sized up can run a smaller tube, but a mill sized down cannot run a larger one.
Three numbers decide the model: the largest OD you need to sell, the thickest wall at that OD, and the annual tonnage. Wall thickness and diameter drive the roll weight, the HF power and the line speed far more than the annual tonnage does. Send those three and we will tell you which model and which roll pass design fit.
