Dismantling joint type F4 PN10 / PN16

Technimex dismantling joints are double flanged fittings that allow longitudinal adjustment in flanged pipe systems (+/- 25 mm adjustable from the middle position). Dismantling joints provide a simple method for installation and removal of flanged valves so also for subsequent maintenance. Typical applications include water treatment, sewage treatment, power generation and pumping stations.
