2.13 Threaded Models FPD350.L6.E1 and FPD350.L7.E1

Warning. Threaded models
FPD350.L7.E1 are designed for 'Hot-Tap' installation.
Observe all relevant safety precautions for drilling into
pressurized pipelines, and ensure the process material does
not exceed the Torbar's specified pressure and temperature
limits.
Install the Torbar as follows:
1. Select the required insertion position and mark the pipe.
2. Align the threaded fitting over the mark and tack-weld it in
place.
3. Using a suitably sized and threaded length of pipe, check
the threaded fitting is aligned correctly – see Fig. 2.2,
page 4.
4. Weld the threaded fitting to the pipe.
5. Referring to Fig. 2.12:
a. Apply suitable sealant to the close nipple

in accordance
instructions.
c. Drill a 6 mm (0.24 in) pilot hole in the process pipe at
the marked position, then drill to the appropriate size
– see Table 2.7.

h. Insert the Torbar into packing gland
i. Turn the Torbar until the indentation marks on the
head are positioned downstream of the flow – see
Fig. 2.1, page 3.
j. Tighten the packing gland bolts
evenly until the packing gland is fully sealed,
ensuring the Torbar is able to slide through it.
k. Carefully open isolation valve

Note. The gear retraction handle is supplied loose
and can be fitted to either side of the gears.
However, ensure the handle is fitted so that the
Torbar is inserted when the handle is turned
clockwise.
n. Optional geared retraction assembly only – turn
the integral handle clockwise until the Torbar
contacts the opposite side of the process pipe.
o. Fully tighten packing gland bolts
Torbar does not turn. Check for leaks.
6. Check that the Torbar is installed correctly and aligned.
