TQ series of hydraulic casing tongs are widely used for making-up or breaking-out of casings or pipes. The series of casing tongs are wholly hydraulic driven. The tongs are configured with a large-torque motor and perform mechanical gearchange. Structure is simple and operation is safe. The casing tongs can be supplied with torque device to perform computer monitoring and managing on pressure, torque and rounds. The casing tong has been granted with National Invention Patent. The casing tongs are designed and manufactured according to SY/T5074 and API Spec 7K "Specification for Drilling Equipment"Model TQ178-16Y TQ340-35Y TQ508-70Y Size range mm 101. 6-178 114. 3-340 244. 5-508 in 4-7 4 -13 9 -20 Max. pressure MPa 18 21 20 psi 2610 3045 2900 Working flow L/ min 110-160 110-170 110-170 gpm 29. 3-42. 7 29. 3-45. 4 29. 3-45. 4 Max. torque Hi. gear kN. m 2. 4-3 4. 0-5. 6 8. 4-10. 7 ft. lbf 1770-2210 2950-4130 6190-7890 Low gear kN. m 15-18 26-35. 2 48. 9-70. 5 ft. lbf 11060-13270 19175-25960 37244-52000 Speed High gear rpm 54-79 57-95 26-43. 6 Low gear rpm 9-13 9-15 4-6. 6 Size mm 1500×760×780 1580×900×860 2080×1280×760 in 59×30×30. 7 62. 2×35. 4×33. 9 82×50. 4×30 Weight kg 560 760 1550 lb 1230 1670 3410
