Double flanges transmission joint for water engineering
The double flange transmission joint is composed of body, sealing ring, gland, telescopic short pipe and
other main components. The double flange transmission joint is applicable to the pipeline evenly connected with the flange on
both sides. During installation, adjust the installation length
between the two ends of the double flange transmission joint and the flange, and tighten the gland bolts diagonally and evenly
to make it a whole with a certain amount of displacement, which is
convenient for installation. When the double flange transmission joint is repaired, it shall be adjusted according to the field size. The double flange transmission joint can transmit the reverse axial thrust to the whole pipeline in
operation.
Performance of double flange transmission joint
1. The double flange transmission 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 transmission 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 transmission 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.

Note:double flange transmission joint is suitable for connecting both sides with flange. During
installation, adjust the connecting length of both ends of the
product, tighten the gland bolts in turn and adjust the limit nuts.
In this way, the pipeline can expand freely, lock the expansion,
and ensure the safe operation of the pipeline.
