Application of Bellows Expansion Joints:

The bending force balanced bellows expansion joint is used for the connection between equipment, serving to compensate for the thermal expansion of the pipeline between the two pieces of equipment, reduce the force exerted on the equipment due to misalignment, and facilitate equipment operation. The use of the bending force balanced bellows expansion joint ensures that the equipment is not subjected to blind plate force caused by internal pressure, improving the equipment's stress condition, and allowing for simple equipment fixation. The bellows expansion joint, as a flexible connecting pipe for pumps, is applied to the inlet and outlet pipelines of the pump. The general-purpose expansion joint installed on the pump's inlet and outlet pipelines compensates for pipeline thermal expansion, reduces the thrust on the pump due to pipeline thermal expansion, or absorbs vibrations generated during pump operation. Although the constraints are complex on various levels, any complex piping system can be divided into several simpler individual pipes, such as "Z" and "Π" shaped sections, by using a few fixed supports at different locations. Each pipe section's deformation and compensation amount should be individually acknowledged. Due to the wide variety of compensators available, correct selection is crucial. Therefore, during the overall planning of the piping system, it is essential to fully consider the pipeline layout and the planning of the support system (including fixed pipe racks, guided sliding pipe racks, etc.), as well as the design and equipment of compensators to ensure a safe, reasonable, applicable, and economical combination. The bellows compensator, centered around the bellows, is a flexible element that provides compensation in three directions: axial, lateral, and angular. The axial type compensator is used to reduce the self-excited phenomenon of the medium. Since there is no inner sleeve pipe inside the product, it largely restricts the radial compensation capability, so it is generally used only to absorb or compensate for the axial displacement of the pipeline (if a small amount of radial displacement is required in the pipeline system, this can be specified during ordering): the lateral displacement compensator (large bolt) primarily absorbs lateral displacement perpendicular to the compensator axis, while the small bolt lateral displacement compensator is suitable for absorbing lateral displacement and can also absorb a combination of axial, angular, and any three-directional displacements: the hinge compensator (also known as the angular compensator). It is used in pairs or triples (a single hinge compensator has no compensating capability) to absorb lateral deformation within a single plane. The universal hinge (angular) compensator, consisting of two or three units, can absorb deformation in three-dimensional directions.
