Install the Torbar as follows:
1. Install the flanged pipe fitting (stand-off) – see Section
2. Position the gasket onto the Torbar flange and carefully
insert the Torbar through the flanged pipe fitting (stand-off)
until the two flanges mate squarely.
3. Turn the upper flange until the indentation marks on the
head are positioned downstream of the flow – see

2.9 Flanged Models FPD350.(T4/T5).E2
Install the Torbar as follows:
1. Install the flanged pipe fitting (stand-off) – see Section
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 end-support cup over the tip of the Torbar,
ensuring the tip is concentric with the hole, and tack-weld
the end-support cup in place.
6. Remove the Torbar and complete the support cup
full-penetration weld.
7. 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 end-support cup.
8. Turn the upper flange until the arrow on the top face of the
Torbar flange is aligned with the direction of flow.
9. Fit the flange securing bolts and tighten equally and
evenly, observing correct procedures appropriate to the
flange.
10. Check the Torbar is installed correctly and aligned.
Note.
For models with a flanged end-support fitting
