Wellhead Pressure Blocking
Feedthru for Metal Clad
Instrument Cables
The BIW Feedthru for metal clad instrument cables
provides a secure pressure barrier for single conductor
instrument cables, even in the event of a cable failure
downhole.
This robust pressure-blocking connector is intended for
easy installation on top of the tubing hanger or on the top
flange. This configuration allows the tubing hanger to be
landed without delay.
The connector will withstand up to 10,000 psi pressure,
in the event of a downhole cable failure. It is intended for
installation in any type of well where a permanent
downhole gauge may be installed.
Installation is fast, easy, and requires minimal training
or experience. No soldering is required at the wellhead.
The Feedthru provides sealing to the exterior of the metal
clad cable, and it provides a positive block against fluids
or gasses that could pass through the metal clad cable in
the event of a downhole breach. Sealing is achieved with
a combination of tapered sealing threads and O-rings.
Attachment to the wellhead requires only a 1/2-inch
(13mm) opening (1/2-14 NPT).
The installed length of the feedthru, including top
connector is less than 13-inches (33 cm). The maximum
diameter of the installed device is 2.25 inches (5.7 cm).
The Top
Connector is
angled with a 60degree bend to
help guide the
cable away from
the wellhead.
