Double Flange Limit Expansion Joint Metallic For Water Engineering
The double flange limit expansion joint consists of the main body, the sealing ring, the gland, the
telescopic short pipe and other main parts. aDouble flange limit
expansion joint is a new product that connects pumps, valves and
other equipment with pipelines. Double flange limit expansion joint
connects them into a whole through full bolts, and has a certain
displacement. In this way, Double flange limit expansion joint can
be adjusted according to the installation size on site during
installation and maintenance, and the axial thrust can be
transferred back to the whole pipeline during work. This not only
improves work efficiency, but also plays a certain protective role
for pumps, valves and other equipment.
Performance of double flange limit expansion joint
1. The double flange limit expansion joint should have high
compression capacity to ensure the operation of the pipeline during
the crustal movement. It has high corrosion resistance, and the
expansion joint is buried underground all the year round, so it has
high requirements for corrosion resistance.
2. The double flange limit expansion joint can move axially, which can eliminate the stress of thermal
expansion and cold contraction caused by seasonal changes or
different media. The steel expansion joint is made of steel, and
the rubber joint has strong corrosion resistance and flange
connection.
3. The double flange limit expansion joint is easy to install and
maintain to avoid unnecessary trouble during welding. Special
design process is adopted and limit bolts are reinforced to make
the pipeline more reliable in operation.
