    Product Description

    Single Universal Hinge Type Expansion Joint / Expansion Bellows For Pipes

    Single universal hinge type expansion joint

     

    Product description

     

    Pressure range of expansion joint:

     

    The pressure of various expansion joints is the design pressure Pd (MPa) at t=20℃, the pressure range is usually from vacuum to 4MPa, if there is a special ultra-high pressure to request, we can also specially designed.Before each product leaves the factory, each work sequence shall be subjected to 100% pressure test and other required tests. Only after meeting the standard requirements can the product leave the factory

     

    Temperature range of expansion joint:

     

    Other materials can also be used according to the customer's working conditions.When the pipe and liner are made of carbon steel, the operating temperature of the expansion joint ranges from -20℃ to 420℃.When the pipe is made of stainless steel (the same bellows), the temperature range of the product is -196 ~ 700℃.

    There are unidirectional and universal angular expansion joints.

    (1) unidirectional angular type: it can only bend and deform to form angular displacement.Internal pressure thrust is borne by the hinge.

    (2) universal angular type: universal angular type corrugated expansion joint is characterized by universal hinge, which can be bent in any plane across the axis.Angular forms are generally two or three combinations of offset line displacements.
