Universal hydraulic suspended tongs

The tongs are intended for mechanization of tonguing and uncoupling of drill pipes in consistence with GOST 632-80 (acme thread) with monitoring and automatic limitation of torque during round-trips in the process of oil-well and gas-well drilling.

The tongs are suitable for use on I-XI class drilling rigs in consistence with GOST 16293-82 in moderate and cold climates.

Main version of the tongs is U1.1, allocation category 1 in consistence with GOST 15150-69.

Components:

· Actuator – provides for reliable capture of casing pipes by outer diameter and required torqueing / in container.

· Power plant with hydraulic hose – converts electrical power into mechanical power thus supporting actuator’s operation / in container.

· Torquemeter - measures pipe torque and creates thrust impeding rotation of the actuator’s frame / in container.

· Spring suspension – compensates vertical shift of the actuator during tonguing and uncoupling of case pipes.

· CDRS – control and data recorder system – automatically monitors and controls tonguing and uncoupling of pipes, performs data logging in the form of protocols and diagrams e.g. momentum vs. time for each pipe, determines torque and shuts down the actuator when the required value is reached, uncouples and screws up joints, if necessary, displays tonguing parameters on the screen of the controller and stores them on the flash-card for further processing on the computer: viewing of tonguing, uncoupling and screwing up diagrams, printing / in container.

The product has a certificate of compliance № ROSS RU.HHO04.B0070 issued by NP RMNTK "Nefteotdacha" - VNII neft-sertifikatsiya.
