FRIALEN
®
Shut-off Saddles (see
Figure 19) are prepared for
installation and fused analogue to
FRIALEN
®
Pressure Tapping Tees
(see Chapters 5.1.1 – 5.1.4). The
tapping of the pipe can be made
after cooling down (see item 5.1.5)
and observing the installation in-
structions of the tapping/shut-off
saddle installation equipment of the
relevant manufacturer.
Installing the brass plug
The plug is to be installed up to the
stop; the O-ring must seal in the
dome. The required torque of
approx. 150 Nm can be achieved
through a lever. A visual control
takes place (Figure 20). A torque
screwdriver is not necessary.
After fitting the brass plug either the
plastic nut must be screwed on or a
FRIALEN
®
cap for Shut off Sadd-
les must be fused on, ensuring that
the usual scraping and cleaning
work is carried out (see Figure 21).
