Pneumatic Pipe Weight Compensator
This Unit is intended to hang a string of pipe in the derrick. Then adjust this string of pipe to the proper height for threading it into the box end of a pipe held in the slips and allow for downward movement while the threads are engaged and torque is applied to tighten the connection under controlled conditions.
This unit is hooked up to a standard air supply.
The air preparation unit will allow filtering and conditioning the air as it enters this circuit. It also allows setting the desired pressure for the circuit. This air preparation unit is also equipped with a safety shutoff that, when engaged, doesn't allow to pressure up the circuit and decompresses the air in this circuit.
