Single Flange Limit
Single flange limit expansion joint: This product is used to
connect with the flange while welding with the pipeline. During the
installation of single flange limit expansion joint, adjust the
installation length between both ends of the product and the
pipeline or flange, tighten the gland bolts diagonally and evenly,
and then adjust the limit nut, so that the pipeline can expand and
contract by itself within the expansion range and lock the
expansion amount, Safe operation of pipelines.
Performance of single flange limit expansion joint
1. The single 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 single 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 single 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.
