Larger diameters are limited by the cost of the tooling, the power needed to pull the strip through the mill, and the wear on the drive stands; smaller diameters are limited by the impeder size.The impeder, the device that directs the welding current toward the weld seam, has to fit inside the tube or pipe.

    The mill modulus is 500-1,000 ton/mm for plate rolling mills and 400-600 ton/mm for cold rolling mills. The larger the diameter of the back-up rolls, the higher the mill modulus. A rolling force of the order of 1,000 tons is generated during rolling, so that mill deformation of more than 1mm occurs. Unless this deformation is taken into account, thickness accuracy cannot be ensured ...

    Unlike the plug mill, the mandrel mill reduces wall thickness continuously with a series of pairs of curved rollers set at 90° angles to each other. After reheating, the pipe is passed through a multi-stand stretch-reducing mill to reduce the diameter to the finished diameter. The pipe is then cut to length before heat treatment, final straightening, inspection, and hydrostatic testing.
