1.4. Components and functions
1.4.1. Stainless steel sleeve
1-
Beveled End
The beveled end faces the direction of
flow and improves the hydrodynamics,
prevents solids from depositing, and
increases jetting resistance.
2-
Metal Overlap
The steel sleeve is rolled up smaller
than its nominal diameter. The overlap
is what is left over for expanding to
the pipe wall.
3-
Toothed Strip
The locks that keep the sleeve
expanded run along the toothed strip.
4-
Lock
The lock is a small set of gears that only
moves in one direction, thus keeping the
sleeve expanded.
5-
Adhesive Tape
The tapes are put on at the factory to
protect the sleeve during the transport and
prevent it from unrolling.
6-
Plastic Rivet
The plastic rivet prevents the sleeve from
unrolling and is sheared off during inflation.
1.4.2. Rubber gasket
7-
Circumferential seals
The actual seal is formed by the
circumferential seals compressed
against the host pipe. The
damaged section must always be
between these seals.
8-
Trimming Line
There is a trimming line marked in
the rubber gasket. It shows you
where to cut off the projecting
rubber end (when a single sleeve
is installed).
9-
Projecting Rubber End
The projecting rubber end acts as
a seals between sleeves installed
in a series.
