2.16 Flanged Models FPD350.(H7/H8).E2

Warning. Flanged models
supported in the process pipe at the Torbar tip as well as at
the entry point into the pipe, therefore they cannot be
'Hot-Tap' installed. Before drilling into the pipe, reduce the
pipe pressure to a safe level and remove all hazardous
material. Before inserting the probe, you must also stop the
flow completely, to ensure that the probe can correctly
engage with the end support.
Install the Torbar as follows:
Note. Step 1 is applicable only if the flanged pipe fitting
(stand-off) is not installed.
1. Install the flanged pipe fitting (stand-off) – see Section
2.18, page 24.
2. Measure exactly 180° around the pipe circumference and
mark the pipe.
3. 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 2.9.

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

from the hole on the opposite side of the process
pipe by:
FPD350.H7.E2 – 40 mm (1.6 in)
FPD350.H8.E2 – 65 mm (2.6 in)
When the Torbar is inserted fully, ensure drawbolts

and stop nuts
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.
j. Geared retraction assembly only – turn the
integral handle clockwise until the Torbar protrudes
from the threaded fitting on the opposite side of the
process pipe by:
FPD350.H7.E2 – 40 mm (1.6 in)
FPD350.H8.E2 – 65 mm (2.6 in)
k. Place end support cup
and tack-weld it to the process pipe.
l. Reverse step i (drawbolt retraction assembly) or step
j (geared retraction assembly) and retract the Torbar
by 100 mm (4.0 in).
m. Weld end support cup
n. Repeat step i (drawbolt retraction assembly) or step
j (geared retraction assembly) to re-insert the Torbar

Torbar does not turn. Check for leaks.
5. Check the Torbar is installed correctly and aligned.
6. Pressurize the process pipe and check for leaks.
