The Dialog chemical cutter service is used commonly in wireline pipe recovery operations. It cuts through coiled tubing, tubing, casing, or drill pipe with a cut that does not have a flare and does not distort the pipe ID or OD. This service allows fishing operations to proceed without the need to mill the top of the fish. The cutter is designed to operate in extreme pressures and temperatures and does not leave any debris in the hole. Large diameter versions are available. The chemical cutter service does not require torque to be applied to the pipe which is particularly useful in applications where the pipe will turn freely but will not pull free.
