Q140/12Y Well Repair Power Tongs

Overview The XQ140/12Y workover power tong is a new type of open-end power tong used for fast threading in oilfield workover operations. The backup tong and the main tong are integrated. This tong is suitable for oil pipes, small drill pipes and small casings within the range of Φ73～Φ140mm (2 7/8"～5 1/2"), and can be used in both land and offshore oil fields. It has the advantages of simple structure, convenient operation, wide application range, and large output torque, which reduces the labor intensity of oilfield workers and improves work efficiency and workover quality. An optional torque control system can be used to display, record and control the make-up torque.Main technical parameters 1 Main tongs applicable pipe diameter Mm(in)73～140(2 7/8"～5 1/2") 2 Low gear maximum torque kN.m 12 3 Second low gear maximum torque kN.m 7.8 4 Second high gear maximum torque kN.m 4.2 5 High gear maximum torque kN.m 2.5 6 Low gear maximum speed rpm 14 7 Second low gear maximum speed rpm 24 8 Second high gear maximum speed rpm 42 9 High gear maximum speed rpm 72 10 Maximum working pressure Mpa 12 11 Maximum oil supply L/min 120 12 Power tongs transfer weight kg ～520 13 Overall dimensions mm 1060×618×850
