    Hinged type expansion joint with welding ends ISO 9001 certification


    Product description


    Hinged bellows expansion joints are mainly used in various complicated piping systems to compensate the angular displacement of piping systems, such as L-shaped pipes, Z-shaped pipes, U-shaped pipes, etc.Widely used in petroleum, chemical industry, steel, metallurgy, machinery, transportation, transportation, shipbuilding, dock, construction, rubber, papermaking, textile, electric heating network, pharmaceutical, medical and other industries.




    The hinge-type corrugated expansion joint absorbs the angular displacement caused by thermal expansion or contraction along the axial direction of a pipeline, a conveying channel or a container through a change in its angle.Usually two or three pieces are used in combination. The compensation amount is proportional to the distance between the two products. Its advantages are small size and light weight. The pressure thrust of the product is borne by the hinge member. The angular hinge ripple compensator can compensate the pipeline in any direction.Angular displacement.




    1. The hinge type corrugated compensator should be checked for its model, specifications and pipeline configuration before installation. It must meet the design requirements.


    2. For the compensator with inner sleeve, care should be taken to make the direction of the inner sleeve consistent with the medium flow direction. The hinge rotation plane of the hinge type compensator should be consistent with the displacement rotation plane.


    3. A "cold tight" compensator is required. The auxiliary components used for pre-deformation should be removed after the pipeline is installed.


    4. It is strictly forbidden to use the method of deformation of the corrugated compensator to adjust the installation tolerance of the pipeline, so as not to affect the normal function of the compensator, reduce the service life and increase the load of the piping system, equipment and support members.


    5. During the installation process, the welding slag is not allowed to splash on the surface of the wave shell, and the wave shell is not allowed to be damaged by other machinery.


    6. After the installation of the piping system, the yellow auxiliary positioning components and fasteners 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 environmental protectionFull compensation capacity.


    7. All moving components of the compensator must not be stuck by external components or limit their range of movement, and normal movements of all moving parts should be guaranteed.


    8. During the hydrostatic test, the secondary fixed pipe frame equipped with the compensator pipe end should be reinforced so that the pipe does not move or rotate.For the compensator used for gas medium and its connecting pipeline, pay attention to whether it is necessary to add a temporary support when filling with water.The 96 chloride ion content of the water-washing liquid for the hydrostatic test does not exceed 25 PPM.


    9. After the hydrostatic test is over, the accumulated water in the wave shell should be drained as soon as possible, and the inner surface of the wave shell should be dried quickly.


    10. The insulation material in contact with the compensator bellows should be chlorine-free.
