3 Torbar Removing and Refitting
3.1 Threaded Models FPD350.T3 and
FPD350.T4.(E1/E2)
3.1.1 Removing
Remove the Torbar as follows:
Warning. Failure to reduce the pipe pressure to a safe level
and remove all hazardous material prior to removing the
Torbar could result in serious injury to personnel.
1. Reduce pipe pressure to a safe level and remove all
hazardous material.
2. Remove the compression fitting.
3. Remove the Torbar.
3.1.2 Refitting
Refit the Torbar as follows:
1. Slide the compression-fitting assembly onto the Torbar.
2. Insert the Torbar through the threaded fitting into the pipe
until it either touches the opposite internal wall (
FPD350.T3.E1 and FPD350.T4.E1
fitting (
model FPD350.T4.E2
3. Apply appropriate sealant to the threads of the
compression fitting.
4. Screw the compression fitting into the threaded fitting until
hand-tight.
5. Turn the Torbar until the indentation marks on the head are
positioned downstream of the flow – see Fig. 2.1, page 3.
6. Holding the head of the Torbar with a wrench to maintain
correct orientation, use a long wrench to tighten the
compression fitting until approximately one thread is left
exposed under the nut, ensuring the Torbar does not turn.
7. Check the Torbar is installed correctly and aligned.

3.2 Flanged Models FPD350.T3; FPD350.T4.(E1/E2)
and FPD350.T5.(E1/E2)
3.2.1 Removing
Remove the Torbar as follows:
Warning. Failure to reduce the pipe pressure to a safe level
and remove all hazardous material prior to removing the
Torbar could result in serious injury to personnel.
1. Reduce pipe pressure to a safe level and remove all
hazardous material.
2. Remove the flange securing bolts.
3. Remove the Torbar.
3.2.2 Refitting
Refit the Torbar as follows:
1. Position the gasket onto the Torbar flange and carefully
insert the Torbar through the flanged pipe fitting (stand-off)
(ensuring the tip of the Torbar enters the opposite fitting –
models FPD350.T4.E2 and FPD350.T5.E2
flanges mate squarely.
2. Turn the upper flange until the indentation marks on the
head are positioned downstream of the flow – see
Fig. 2.1, page 3.
3. Fit the flange securing bolts and tighten equally and
evenly, observing correct procedures appropriate to the
flange.
4. Check the Torbar is installed correctly and aligned.
