Large, the contact surface is large, the friction is strong, the oil pipe is not damaged and not deformed, especially suitable for tubings and casings made of 3CRr, 22Cr and 13Cr materials.
1. Fully hydraulically driven, the maximum torque can reach 50,000N.m, and it can hold the oil pipe with the diameter of up to 5".
2. Adopting two-plate type full-cohesion clamping mechanism, different specifications of the tubing body and coupling are equipped with corresponding curved arc plates, the surface of the tubing clamped is absolutely free of tooth marks, no stress concentration phenomenon, avoiding underground Secondary accident.
3. When the shackle is shackled, the back tongs will float in parallel with the main tongs, and the centering will be automatically centered to avoid the adverse effects caused by the main back tongs unbalanced to the thread and avoid the phenomenon of sticking.
4. The new toothless tooth is made of special plastic material. It does not slip and does not damage the oil pipe. The primary protective film holds at least 30 oil pipes. Even if it is slippery due to the tightness of the clamp, it will not hurt the oil pipe surface.
5. The automatic torque control system has high precision in torque value setting, control, storage and printing.
6. The safety door is operated by mechanical control, which is simple, safe, more stable and convenient.

Portable Torque Meter (WY-12) It consists of the following seven parts: laptop, power adapter, torque controller, load cell, speed sensor, solenoid valve, communication cable.
● se a strain sensor to measure torque without adding hydraulic oil.
● Cooperate with the solenoid valve on the hydraulic station to achieve automatic control of the upper buckle torque.
● Use photoelectric encoder to record the number of turns and the speed.
● The process parameters of the buckle can be set according to the operation requirements.
● Suitable for round threaded buckles.
● Applicable to VAM TOP, BGT1, FOX, 3SB and other special threaded buckles, can detect and record tightening torque, shoulder torque (Note: the same as the "shoulder torque" below, the same term used in translation), shoulder number , shoulder torque ratio.
● Display, control, and record the buckled process data, and record the buckle process data on the memory for later query.
