Manufactured to AWWA C219 under quality management
systems accredited to ISO 9001:2008.a double flanged
composite fitting featuring a telescopic action between
a flanged spigot and a flange adaptor. The joint is
designed to provide longitudinal adjustment in flanged
.4 pipe systems. Dismantling joints provide a simple
method for the installation and removal of flanged
valves, pumps, flow meters, flanged pipes and pipe
fittings. Tie rods arc provided for final anchoring and
location and these also double as mating flange jointing
bolts, reducing the number of these required.

PRODUCT RANGE
The dismantling joint range fromJDFF extends from
50mm to 2000mm and whilst the chart indicates
flange ratingsof PN16/10, all common drillings
are available in pressures up to 40 BAR. The range

Thickness of flanges will not necessarily be the same as
the mating flange. Flanges and flange adaptors will not
be subject to full end or side thrust, most of which is
absorbed by the flexibility in the rubber gaskets. Pipe
end should be smooth, with no seams, score marks,
dents or ovality.

INSTALLATION
This is extremely simple and is generally done with
the flange adaptor end connected to the valve or
other appurtance. In cases where a full faced flange is
required, for example on wafer butterfly valves, the joint
is simply turned round to use the spigot flange instead.
