Product Performance of dismantling joint flange adapter

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

LIWEI  Dismantling Joint are particularly suitable for simplifying the installation & removal of isolation valves, control valves, check valves, non-return valves, flow metering valves, pump sets, pressure reducing valves, flanged pipe & fittings.

1. provide adjustability to equipment installations by combining a Flanged Coupling Adapter and a Flanged Spigot into one assembly.

2. Dismantling Joint applications include valve, pump, meter and other flanged fitting installations.

3. Longitudinal adjustment is provided by the telescoping action of the Spigot inside the Flanged Coupling Adapter.

Applicable Scope of dismantling joint flange adapter

The metal product is functioned with pull and pres-sure resistance and excellent seal performance and easy installation. Hence it is widely used in power, metallurgy, drainage and sewage disposal to connect pump, vale and pipe, etc. It also has some multi-directional displacement during pipes operation so as to release blind plate propulsion and protect pipes, especially it makes it easy to install and maintain pipes. However, force- transferring joints shall be used on the pipe corner and pump exit, because, the joints can transfer blind plate propulsion from pump start to pump and pipe through force- transferring bolt and prevent pull to centralize close to pipe or pipe or damage equipment by impact force. Other joints can be selected freely for other positions. Our tenet: your trust is our honor and we will manufacture high- quality products for you.
