Manufacturing process
Ribbing process
Ribs are obtained through cold drawing process on a grooved plug from hollows supplied by SMP mills. After drawing and ribbing pass, tubes are heat treated to get specified metallurgical requirements. Before final cutting, tubes are 100% checked by Eddy Current and/or Ultrasonic test, depending on customer’s requirements.
