The Dismantling Joint is particularly suitable for simplifying the installation and removal of:

Isolation valves
Non return valves
Flow metering equipment
Pump sets
Pressure reducing valves
Flanged pipe and fittings

FEATURES & BENEFITS:

Longitudinal adjustment

The Dismantling Joints are capable of accommodating up to 50mm / 2" longitudinal adjustment dependant on diameter. This adjustability is provided by the telescopic action of the flanged spigot within the flange adaptor. The Dismantling Joint can be locked at that length with the tie bars supplied. Longitudinal adjustment of this magnitude allows for fast and simple maintenance of valves, pumps etc. and simplifies future pipework modifications, often resulting in reduced down time and eliminating the need for more complex anchoring systems.

Ease of Installation

The Dismantling Joint can be installed with the aid of a spanner and a torque wrench, no specialist equipment is required.

Speed of installation

The Dismantling Joints re supplied with high tensile steel tie bars to IS-1363. Because of the high quality of the tie bar material, fewer tie bars are required. Consequently there are fewer flu bars than flange holes (additional flange connecting bolts not supplied). The tie bars supplied with the Dismantling Joint also act as flange grouting bolts, reducing the number of flange bolts required.

Sealing

Unlike other styles of Dismantling Joint, the gasket of the Dismantle rig Joint Is compressed independently of the tie bars. Compression of the gasket is & achieved by following standard flange adaptor installation procedures and speeding installation. lt also allows for a socket and torque wrench to be used. Ensuring that seating failure cannot occur as the gasket is compressed to the required torque.

Range

This Dismantling Joint can be supplied in any nominal size from DN4O(1.1/2) upwards with mcst common flange drillings such as PN16, N10.ANSl etc. Dismantling Joint specials for specific project requirements can also be produced.

Corrosion and Protection

The flange adaptor and flange spigot components of a Dismantling Joint are coated with the epoxy coating as standard ensuring that dismantling joints are well equipped to withstand transport, storage, site and corrosion damage. Alternative finishes are also available. All tie bars are Zinc plated.

Working Pressure

All z4 Dismantling Joints are fully end load resistant and have a pressure rating equal to that of the flange.

Full Face Flange

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

Product Quality

Dismantling Joints are designed and manufactured under a quality management system and have tested by the comprehensive in house research facilities to the most exacting performance requirements of WRC Water Bye-laws scheme (WBS).As with all the products, Dismantling Joints are designed to outlast the pipes on which they are fitted.

Gaskets

Dismantling Joints are fitted with EPDM water quality gaskets as standard. For other applications or alternative please ask for details.
