The dismantling joint range was developed to provide greater versatility for the designer at the planning stage and the engineer in the installation stage of flanged pipe work systems and to allow for simple maintenance programs.
Allows for Adjustment
The dismantling joints are double flanged fittings that accommodate up to 100mm (4”) longitudinal adjustment and can be locked at the required length with the tie bars 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.
Easy to Install
The installation is also straightforward using just a spanner and torque wrench to tighten the high tensile steel or stainless steel tie bars. With fewer tie bars than flange holes and the tie bars acting as flange jointing bolts the process is speeded up but still offers a secure, rigid, fully end load resistant system with a pressure rating equal to that of the flange.
The Range
A comprehensive range is available from DN65 (2½”) to DN4000 (160”) with virtually any flange drilling or pressure rating supplied, although larger sizes and custom made. Dismantling joints can be designed and built on request.
