The Burst Disc Circulation Sub is a standard coiled tubing toolstring component that is used in conjunction with tools that require drop balls etc., and that need to be circulated into the coiled tubing.

The Burst Disc Circulation Sub is incorporated into the coiled tubing toolstring just below the tool that requires a drop ball.

Should circulation be lost due to a down hole restriction, a predetermined pressure applied to the coil will burst the disc in the sub and re-establish circulation.
