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.

Note:Double flange limit expansion 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.
