Description
Technical process of the welded pipe mill line: uncoiler, leveler,
shear and welder, accumulator, forming, HF welding, squeezing,
deburring, iron roll, air cooling, water cooling, sizing, flying
saw, straighter, end facing, packing
Roll type flattened consists of two rows of same diameter rolls
Staggered at equal intervals
Upper rolls are installed on the upper stands
Reducer via transmission shaft equipped with universal joint powers
drive rolls
Flattened steel strips pass between two rows of rolls, where
repeated elastic and plastic bending flattens them, then feeding
