Blue Single Flange Limited Telescopic Joint Vssj-1 (Bf)

Single Flange Limited Telescopic Joint VSSJ-1 (BF) is formed by adding a limit device to the basic sleeve Type Expansion Joint and locked at maximum expansion by double nut. The pipeline can thus freely expand in certain limit. When maximum valve is reached, it will be limited and effectively assure the pipeline working safety. Limited expansion joint is especially suitable for pipeline connection where vibration occur, where taper connection requested and bend pipeline connection.
Dresser Couplings are particularly suitable for simplifying the installation and removal of isolation valves,control valves, check valves, non-return valves, flow metering valves, pump sets, pressure reducing valves, flanged pipe fittings.The simplicity and versatility of the fittings make them suitable for many applications including pumping stations, water treatment works, sewage treatment works, plant rooms, meter chambers, power generation equipment, gas distribution stations.

1. Self -anchoring couplings and flange adpators
2. For ductile iron or steel pipes
3. Easy to use and to install
4. All weather installation
5. Can even be installed under water
6. Fully end load bearing
7. Easier fitting on oval pipes
8. Ideal for pumped sewerage pipelines

During the installation, adjust the installation length to the pipe and flange on the both sides, screw the bolts firmly one by one, weld the short pipes with the pipe, and then adjust the limited nut. This method makes it possible for the pipe to expand and contrast freely within the allowable range of the expansion joint. It also can secure the safe operation.

Our Dresser Coupling designed and manufactured to ISO 9001: 2008 and tested to the most exacting requirements of Water Regulatory Advisory Scheme for use with potable water.
