Large pull rod horizontal expansion joint

    The large pull rod ripple compensator, also known as the compound pull rod ripple compensator or the large pull rod compensator, is a flexible component composed of two identical corrugated pipes and end pipes, end plates, and pull rods. It is a relatively new type of ripple compensator, which has the advantages of large compensation, small rigidity, no medium pressure pushing force, safety, no leakage, and low cost. Getting more and more applications.

    Product features:

    1. The elastic corrugated pipe structure of the large pull rod type corrugated compensator gives it the characteristics of low rigidity, large compensation, and low thrust on the bracket.

    2. The large pull rod corrugated compensator is connected to the pipeline by welding or flange, which is not easy to leak, has good sealing, and is safe and leak free.

    3. Due to its simple installation of fixed brackets and relatively low force, its price is also relatively low, which is 3-4 times cheaper than ordinary compensators.

    Working principle:

    The large pull rod corrugated compensator compensates for the lateral displacement of a single or multiple planes of the pipeline through the angular deflection of the corrugated pipe. Four long pull rods can withstand pressure, thrust, and other additional external forces. The spacing between the bolts at both ends of the pull rod has been adjusted before leaving the factory. Before installation, the large pull rod is loose. After compensating for deformation, the large pull rod can limit the deformation and protect the corrugated pipe. Before installing the large pull rod ripple compensator, it is necessary to perform cold tightening in the opposite direction to obtain greater working compensation capacity. Therefore, in the cold state, the compensator is in a negative deformation state. After the pipeline is heated and stretched, the corrugated pipe relies on flexibility to deform laterally. The compensator can appear in a working deformation state on the appearance, and the thermal expansion of the pipeline can be compensated.
