Stretching, reducing on a tube or pipe mill - The FabricatorMar 7, 2013 . Another way to skin this is to form the tube to 0.500 in. dia., then use additional roll stands to reduce its size. A conventional forge welding mill already includes sizing stands to reduce the tube to its final size, normally a 1 percent reduction. Adding a few roll stands and using the cold-stretch-reducing.reducing stretch mill roll nomemcalacutre,Rolls for Section, Loosening, Straightening, Reducing MillsContinuous Research and Development in the last few decades, Kay Jay Chill Rolls ensures our customers to have a good quality and high performance mill rolls for steel re-rolling, stretch reducing mills, loosing mills, straightening mills, sizing mills, etc. With the help of our valued customer and their important feedbacks,.
