double flange dismantling joint

Manufactured tounder 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.
