Different from the traditional chip or sleeve thread processing technology, this equipment adopts the world's leading new rolling process new technology to machining pipe thread. This thread has high consistency and stability, screw surface roughness is at least Ra 0.8, thread tooth is strong, tooth surface and root bottom are rolled to cold hardening, improve mechanical connection strength twice and more, sealing performance greatly improved, especially for galvanized welded pipe surface zinc layer retention, more than 30 times to improve the working life of galvanized pipe, It is the revolution of pipe thread processing technology.
