Type ‘JU’ and ‘JU-H’ High Pressure
This rugged stripper cleans oil and other materials from
tubing as it is being pulled and prevents escape of oil or gas while
running or pulling tubing under pressure. The stripper employs a heavy
duty rubber that can be changed without removing the stripper from the
wellhead. The unique, accordion-style design of this rubber allows easy
passage of tubing couplings without leakage. The flexible,
tight-gripping rubber works equally well on round, square, or hexagonal
shapes. The major components are fabricated of tough cast steel for
long, trouble-free service.
The housing of the Type ‘JU’ stripper is a single casting, with a
flanged bottom connection for easy attachment of API flanges. Six 1-1/8
in. stud bolts transmit tubing load from the packing gland to the
housing. These bolts also provide the means for adjusting the packing
rubber, allowing three inches of travel for adjustment and take-up of
wear. The rubber may also be adjusted easily by backing off the stud
nuts and setting tubing weight on top of the stripper. The flat top
provides a suitable base for any Guiberson tubing spider. The Type
‘JU-H’ features a hydraulic actuator which allows the stripper rubber to
be compressed quickly and safely without stopping operations or going
near the wellhead.
Also available is the Type ‘H’ actuator kit for installation on any Type
‘JU’ stripper for full hydraulic operation.
