Three Features of Ductile Iron Dismantling Joint

Developed for Complete Versatility

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 theprocess is speeded up but still offers a secure, rigid, fully endload resistant system with a pressure rating equal to that of the flange.

The Range

A comprehensive range is available from DN40 (1½”) to DN2400 (80”) with virtually any flange drilling or pressure rating supplied, although larger sizes and custom made Dismantling Joints can be designed and built on request.
