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.
