Manufactured to AWWA C219 under quality management systems
accredited to ISO 9001:2000, the DJ Dismantling Joint assembly is 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
pipe systems. Dismantling Joints provide a simple methodfor the
installation and removal of flanged valves, pumps, flow meters,
flanged pipes and pipe fittings. Tie rods are provided for final
anchoring and location and these also double as matingflange
jointing bolts, reducing the number of these required.
The Dismantling Joint range from DJ extends from 50mm to 2000mm and
whilst the chart indicates flange ratings of PN10/16, all common
drillings are available in pressures up to 40 BAR. The range
indicated overleaf is typical and DJ can manufacture to specific
customer specifications and dimensions on request.
Thickness of DJ 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 is extremely
simple and is generally done with the flange adaptor end connected
to the valve or other appurtenance. 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.
