Let’s take a closer look at the classification of bellows expansion joints.

Classification of Bellows Compensators:Axial-type bellows compensators—mainly include internal-pressure bellows compensators, external-pressure bellows compensators, double-effect bellows compensators, unconstrained bellows compensators, and directly buried bellows compensators.Lateral-type bellows compensators—include large-stroke lateral bellows compensators and small-stroke lateral bellows compensators.
Classification of Bellows Compensators:Axial-type bellows compensators—mainly include internal-pressure bellows compensators, external-pressure bellows compensators, double-effect bellows compensators, unconstrained bellows compensators, and directly buried bellows compensators.Lateral-type bellows compensators—include large-stroke lateral bellows compensators and small-stroke lateral bellows compensators.
Angular bellows expansion joints—single-hinge bellows expansion joints, universal-hinge bellows expansion joints, and double-hinge bellows expansion joints; pressure-balanced bellows expansion joints—straight-tube pressure-balanced bellows expansion joints, curved-tube pressure-balanced bellows expansion joints, and internal-and-external-pressure-balanced bellows expansion joints. Bellows expansion joints are available in nominal diameters ranging from DN32 to DN8000, with pressures from 0.1 MPa to 2.5 MPa. Bellows expansion joints are custom-manufactured products.
Which specific type of bellows compensator should be selected? When placing your order, please provide the following information: nominal diameter, medium, pressure, temperature, compensation amount, and connection method. Our technical staff will design a bellows compensator that meets your application requirements by taking into account the external operating environment and the provided parameters. Installation precautions for bellows compensators: Before installation, first check whether the type and specifications of the bellows compensator comply with the design requirements.
The direction of the inner sleeve of the compensator equipped with a flow guide cylinder must be consistent with the flow direction of the medium. Do not attempt to adjust installation misalignments in the pipeline by deforming the bellows compensator, as this could compromise the compensator's normal function. During installation, prevent welding spatter from landing on the surface of the bellows shell, and ensure that the bellows shell is not subjected to any other mechanical damage.
