• Burst Disc Circulation Sub


    The burst disc circulation sub is a standard coiled tubing toolstring component that is used in conjunction with tools. 

    The burst disc circulation sub is incorporated into the tubing toolstring just below the tool that requires a drop ball. Should circulation be lost due to a downhole restriction, a predetermined pressure applied to the coil will burst the disc in the sub and re-establish circulation.

    Burst disc circulation subs are supplied with a blanking plug for the burst disc. When ordering burst disc circulation subs, customers should choose the burst discs they require separately.


    • Various burst disc pressure ratings available require drop balls that need to be circulated into the coiled tubing.
