SECTORS
The DTI Coiled Tubing Hydraulic Knuckle Joint with Adjustable Bleed Port is a coiled tubing service tool used to provide a controlled deviation within the coiled tubing tool string. The knuckle can offer a maximum deviation of 15°. The hydraulically activated bend in the DTI CT Hydraulic Knuckle Joint can support CT logging, Stimulation activities or help with cleanout runs, for example, to direct jetting nozzles close to the casing wall.
A primary application for the Hydraulic knuckle Joint is in conjunction with the DTI Hydraulic Indexing Tool and if required the Velocity Check Circulation Valve as part of a lateral re-entry system.
The tool features a bleed port which opens when the knuckle joint reaches maximum deviation. An adjustment screw has been added to the bleed port to make assembly easier and ensure the bleed port opens at the required deviation.
