Offshore Specialty Torque and Torque+Angle Tools
The increasing demands of the subsea industry and Remote Operated Vehicle (ROV) manufacturers and operators means that, alongside our established reputation as highly skilled providers of equipment for use in refineries, pipelines and oil and gas installations, it is only natural that Norbar are pioneers in the field of weight reduction in high torque gearboxes; integration of torque measurement into gearboxes with the minimum impact on weight; and size and modification of gearboxes and torque transducers for harsh environment and subsea use.
Valve Testing Kit
The Norbar Pneutorque® range of pneumatic torque multipliers apply smooth, controllable torque up to 300,000 N.m (220,000 lbf.ft) which is ideal for testing all kinds of valves and valve actuators even up to the very largest sizes.
Combined with a tool controller and data logging facilities a large range of tests can be carried out and results recorded.
- Tool controllers available for in factory use or housed in IP67 rated case for por tability and outside use.
- Torque values from 160 to 300,000 N.m can be accommodated
- Pneumatic valves supplied for control of torque tool
Can be supplied with or without torque reaction
Tests that can be performed by combining the torque tool with the appropriate transducer and
controller include:
- Torque only
- Torque and turns for multi turn valves
- Torque and angle for ball valve testing and where more precision is required
- Single actuation and cyclic testing
- Data logging of results
