Step 6
At the last gap, carefully interleave the
studs and spikes, locking home the fish
plates and running the nuts to about ¾
down each stud.
Do not at any point close any gap as this
will severely compromise the ability of
the Tapping band to seal in the future.
Step 7
Before tightening the nuts, ensure that
the transducer holders are correctly ori-
ented and that they are either correctly
placed over their pre-cut holes, or that a
hot-tap drill can fit into the available
space.
The clearance against a nearby wall can
be improved by rotating the band up to
45° from the horizontal.
Step 8
Take note of the recommended torque
stamped on the band and set the torque
wrench to half that value.
Torque up all nuts in an even manner,
making sure that no gap is closed and
that no one point is unevenly tightened.
Best results are obtained for both the
sealing of the band and the accuracy of
flowmeter calibration when all the gaps
are kept the same.
