A bellows compensator is a type of compensation element. It utilizes the effective elastic deformation of its main component—the bellows—to absorb dimensional changes in pipelines, conduits, vessels, and other components caused by thermal expansion and contraction, or to compensate for axial, lateral, and angular displacements in these same components. It can also be used to reduce noise and vibration. It finds extensive applications in modern industry.

JZM Type Direct-Buried Internal Pressure Axial Bellows Compensator: This direct-buried internal-pressure bellows compensator is suitable for piping systems that require only axial displacement. The product is capable of compensating for both lateral displacement and the combined axial and lateral displacement. However, due to its relatively small compensation capacity, it is generally used primarily for axial compensation, where it can better demonstrate its characteristics, offering a longer service life and enhanced safety and reliability.
JZW Axial-Compression Bellows Compensator: The axial-compression bellows compensator primarily absorbs axial displacement and features large compensation capacity, excellent thermal insulation performance, and the ability to effectively remove residual media. BW Unconstrained Bellows Compensator: The unconstrained compensator is used for axial compensation in pipelines, offering substantial compensation capacity as well as strong self-guiding capability and exceptional resistance to bending. As a result, it simplifies the design of pipeline guiding supports, allowing for flexible spacing and installation of these supports.
BZPP-type bypass straight-tube pressure-balancing compensator: Product features: It has the ability to absorb internal pressure thrust and exhibits superior self-balancing performance compared to the ZP type. It features low stiffness and excellent guiding performance. It has a compact external dimension and is highly cost-effective. There are no directional requirements for product installation. Installation and usage precautions: To reduce elastic reaction forces, all products have undergone a 50% pre-stretch; therefore, no further pre-stretching is required during installation.
