• Slim Hole Jetting Head Assembly


    The slimhole jetting head assembly provides the operator with a jetting wash tool assembly that is the same diameter as the coiled tubing. The flapper check valve cartridge is used as the prime safety barrier to prevent back flow from running up the coiled tubing should control of the pump or ancillary surface equipment be lost for any reason.

    By incorporating a conventional roll-on connector and facilitating the choice of jetting nozzles, wash tools, or other slimhole tools into the integrated design, the slimhole jetting head assembly becomes the ideal tool for all slimhole applications.

    Other sizes are available upon request, together with details of other application tools that can be used with the slimhole jetting head assembly. For larger coil sizes, please see roll-on connectors, twin flapper check valves and jetting nozzles.



    • One simple roll-on connection to the coiled tubing is used for easy field service.

    • Roll-on connectors are interchangeable to accommodate different coil weights.

    • Twin flapper cartridges are used in the assembly to provide a double safety barrier.

    • Maximum flow area through the flapper cartridges reduces unnecessary back pressure on the surface pumps.

    • The flow path through the flapper cartridges does not restrict the passage of balls or darts used during operations such as cementing.

    • The flapper cartridges are a field proven construction, featuring the latest material technologies to provide the best possible field life.

    • The unique characteristic of the cartridge and flapper seal is the twin seal. This provides a low pressure non-stick seal and a high pressure metal to metal seal.
