The Dual Circulating Sub is designed as a circulating safety component within the BHA. The design features a Shear-Out Ball Seat coupled with a Burst Disc.

In the event that circulation is lost during a coiled tubing operation, an increase in applied pressure to the tubing will burst the disc, which will regain a sufficient circulation rate to pump a ball.

Pressure can then be applied to the tubing to shear the shear screws and shift the piston to regain maximum circulation.
