Rupture Disc Circulation Sub / Burst Disc Circulation Valve For Coiled Tubing Service
The Rupture disc circulation sub is a kind of circulating valve as a part of tubing tool string. The RD circulating valve is used in conjunction with tools.The rupture 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.
Rupture 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.
