The Manufacturing Process For Tubular Products’ Seamless T
Tubular Products’ seamless mechanical tubing is produced from solid round billets by rotary piercing and then is rolled in an Assel mill equipped with a no-end-loss unit that permits an extremely broad range of diameter/wall thickness ratios. Tubes are then processed through a multiple-pass sizing reducing mill and a rotary sizer.
Tube lengths from the hot mill are slowly air cooled or—depending on size, steel grade and order requirements—moved directly to a unique isothermal annealing furnace.
