End-Support Fitting (mounting types F3 and F4)
Install the Torbar as follows:
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 at the marked position,
then drill to the appropriate size – see Table 2.4.

4. Insert the Torbar through the flanged pipe fitting (stand-off)
into the pipe and check that the tip protrudes through the
hole in the opposite pipe wall when the two flanges mate
squarely.
5. Position the flanged pipe fitting (stand-off) over the tip of
the Torbar, ensuring the tip enters, and is concentric with,
the end support stub.
6. Refer to Section 2.18, Steps 3b and 3c on page 24 and
tack-weld the flanged pipe fitting (stand-off) in place.
7. Remove the Torbar.
8. Refer to Section 2.18, Steps 3d to 3g on page 24 and
complete the installation of the flanged pipe fitting
(stand-off).
9. Position the gasket on the Torbar flange and carefully
insert the Torbar through the flanged pipe fitting (stand-off)
until the two flanges mate squarely, ensuring the tip of the
Torbar enters the opposite flanged pipe fitting (stand-off).
10. Turn the Torbar flange until the arrow on the top face of the
Torbar flange is aligned with the direction of flow.
11. Fit the flange securing bolts and tighten equally and
evenly, observing correct procedures appropriate to the
flange.
12. Check the Torbar is installed correctly and aligned.
13. Position a gasket on the flanged end support flitting,
ensuring the integral support cup faces the tip of the
Torbar.
14. Fit the flanged end support flitting to the flanged pipe
fitting (stand-off), ensuring the tip of the Torbar enters the
integral support cup.
15. Fit the flange securing bolts and tighten equally and
evenly, observing correct procedures appropriate to the
flange.

Warning. Models FPD350.(L6/L7).E1 are designed for
'Hot-Tap' installation.
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 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.
