Product Description

Dismantling Joint is double flanged fittings that accommodate up to 100mm (4”) longitudinal adjustment and can be locked at the required length with the tie rods supplied. Not only does this system allow for fast, easy maintenance of valves, pumps or meters, it simplifies future pipe work modifications and reduces downtime when changes need to be made. 

Wide Application

The simplicity and versatility of the fittings make dismantling joints suitable for many applications including pumping stations, water treatment works, sewage treatment works, plant rooms, meter chambers, power generation equipment, gas distribution stations.

Easy Installation 

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.

Flange Dismantling Joint Design Benefits 

a) Full Range Sealing

For applications where a full-face flange is required,i.e. wafer and butterfly valves, the flange of the spigot piece provides a full flange sealing area. 

b) Excellent Corrosion Protection 

The flange adaptor and flange spigot are well coated, providing excellent protection from transport, storage, site and corrosion damage. The nuts and bolts are also perfectly coated, offering long term protection against corrosion. 

c) Ultimate Sealing Capability 

The EPDM gasket is compressed independently of the tie rods with the sealing capability secured as soon as the fasteners reach required torque.

d) Simple to Fit 

Harnessing is accommodated within the bolt circle, eliminating other complex anchoring systems and reducing space requirements.
