    What is a VSSJA-1(BF) single flange limited expansion joint?

    The VSSJA-1 (BF) single flange limited expansion joint is composed of a loose sleeve expansion joint and a limit short pipe. Single flange loose sleeve limited expansion joint is used for connecting with flange on one side and welding with pipe on the other side. During installation, adjust the installation length between the two ends of the product and the pipeline or flange, tighten the gland bolt evenly diagonally, and then adjust the limit nut. In this way, the pipeline can be freely expanded within the range of the telescopic range, locks the amount of telescopic, and ensure the normal operation of the pipeline.

    Advantages of the VSSJA-1(BF) single flange limited expansion joint:
    1.Long service life
    The VSSJA-1 (BF) single flange limited expansion joint can compensate the axial displacement of the pipeline and greatly reduce the axial thrust during operation, thus extending the service life of the pipeline.
    2.Convenient connection
    The single flange limited expansion joint can prevent the leakage or damage of the compensation joint due to the excessive displacement of the pipeline. It is mainly used for the loose sleeve connection of the pipeline to absorb the axial displacement and relieve the axial pressure thrust within the allowable displacement range. It realizes the connection of the pipeline flange on one side and the inconsistency of welding on the other side, so as to facilitate the connection.
    3.Excellent structure
    The product has stable performance, high material hardness, high anti-pressure resistance, high temperature corrosion resistance, pipe wall thickening treatment.
    4.Stable operation
    The pipeline can be expanded freely within the scope of expansion, locking expansion to ensure the stable operation of the pipeline.
