    Product Description

    Professional Hinged Bellows Expansion Joints Compensator Used In Piping Systems

    Product description


    Hinged bellows expansion joints are mainly used to compensate the angular displacement of various complicated piping systems, such as l-type pipes, z-type pipes and u-type pipes.Widely used in petroleum, chemical, steel, metallurgy, machinery, transportation, transportation, shipping, wharf, construction, rubber, paper, textile, electric power heat grid, pharmaceutical, medical and other industries.



    Installation and use requirements


    1. Before installation, the type, specification and pipe configuration of the hinged ripple compensator should be checked, which must meet the design requirements.


    2. For compensator with inner sleeve, attention should be paid to make the direction of inner sleeve barrel consistent with the direction of medium flow, and the hinge rotational plane of hinge compensator should be consistent with the displacement rotational plane.


    3. For the compensator that needs to be "cold tight", the auxiliary components used for pre-deformation shall be removed after the installation of the pipeline.


    4. It is strictly prohibited to use the method of deformation of ripple compensator to adjust the installation error of pipeline, so as not to affect the normal function of compensator, reduce the service life and increase the load of piping, equipment and supporting members.


    5. During installation, welding slag is not allowed to splash onto the surface of the wave shell, and other mechanical damage is not allowed to the wave shell.


    6. After the installation of piping, the yellow auxiliary positioning member and fastener used for installation and transportation on the corrugated compensator should be removed as soon as possible, and the limit device should be adjusted to the specified position according to the design requirements, so that the piping system has sufficient compensation capacity under environmental conditions.


    7. All moving components of the compensator shall not be jammed by external components or their range of motion shall be limited, and the normal operation of each moving part shall be guaranteed.


    8. During the hydraulic test, the secondary fixed pipe rack with compensator pipe end should be reinforced so that the pipe does not move or rotate.For the compensator for gas medium and its connecting pipeline, it is necessary to pay attention to whether additional temporary support is needed when filling water.The content of 96 chlorine ions in the cleaning solution for hydrostatic test shall not exceed 25PPM.


    9. After the hydrostatic test, the water in the wave shell should be drained as soon as possible, and the inner surface of the wave shell should be blown dry.


    10. The insulation material in contact with the bellows of the compensator shall be free from chlorine




    Nominal pressure :(Mpa) 0.25~2.5

    Nominal diameter: DN32~DN6000

    Single hinged expansion joint consists of a joint joint of a pipe, a bellows pipe and a pair of hinges.

    Single hinged expansion joints can only absorb angular displacement of single plane.

    Single hinged expansion joints shall be used in combination of two or three hinged expansion joints to absorb displacement, and the hinge shall be able to withstand internal pressure thrust.
