Water transmission, structural hollow sections and large API pipe. Line speed falls as diameter rises, because the physics of a large roll is the physics of a large mill.

How to choose the right model
Start from the tube you already sell, not from the machine. The HG273 & HG325 Large Diameter Line covers Ø114 – Ø325 mm at 3 – 10 wall, and it sits between HG273 below and HG325 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.

Not sure which model?
Send the tube OD, the wall thickness and the grade. We will tell you which model covers it and what the roll pass design will look like — before you ask for a price.
