Burst Disc Circulation Sub Primary Coiled Tubing Tools for Downhole Operation
Introduction of Burst Disc Circulation Sub
The burst disc circulation sub is a kind of circulation valve for downhole operation. The burst disc circulation sub is a standard component of coiled tubing tool string that is used in conjunction with tools that require the drop ball. During the coiled tubing operation, when circulation is lost due to downhole restriction, , a predetermined pressure applied to the coil will burst the disc, so that the coiled tubing establishes a circulation passage with the annulus.
Features of Burst Disc Circulation Sub
* Simple and compact structure of the buist disc circulation valve.
* The burst disc circulation valve is easy for operation, maintenance
* The rupture disk is selected according to the operation with high precision of burst pressure.
* Rupture disc of the circulation valve is resistant to corrosion and high temperature
