Burst Disc Circulation Sub
The burst disc circulation sub is a standard coiled tubing tool string component that is used in conjunction with tools.
The burst port circulation sub is incorporated into the tubing tool string just below the tool and 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.
When ordering burst disc circulation subs, please specify size, burst disc pressure rating required, and thread connection.
- Various burst disc pressure ratings available require drop balls that need to be circulated into the coiled tubing
