Model RBF Thermal Packer
Model
RBF is a mechanical-set, pull-to-release thermal packer used in steam injections
and other high temperature environments, it is integrated with an expansion
joint that allows for the tubing movement due to thermal expansion, with a trip
distance up to 6.5m (21.3ft). The packer uses a set of high-performance elements
that could withstand 20Mpa (2900ppsi) of pressure differential under temperatures
up to 300oC (572oF).
The
RBF packer is set by a right-hand rotation and could be released by straight
pull, it adopts a V-ring design in its inner seals, which provides higher
reliability than common O-rings. An optional knock-down joint could be used to
enable hammering to loosen the packer when it gets stuck. A scraping ring
design could remove debris built up on the mandrel and prevent damage to the
inner sealings.
