Compensator selection

Due to the constraints of various aspects, it is quite complicated, but any complex piping system can choose several fixed brackets to choose different settings in different parts, and divide it into several separate pipe sections with relatively simple shapes, "Z" type pipe sections and "∏" type pipe sections, etc., and determine the deformation and compensation amount of each pipe section. Since there are many types of compensators, it is very important to select the correct type. Therefore, in the overall design of the piping system, the pipeline should be fully considered. The design of the direction and support system (including fixed pipe racks, guiding sliding pipe racks, etc.) and comprehensive consideration of the shape and configuration of the compensator to achieve the best combination of safety, rationality, application and economy. The bellows compensator is a flexible element with a bellows as the core, and compensates in three directions in the axial, lateral and angular directions on the pipeline. Axial compensator in order to reduce the self-excitation phenomenon of the medium. There is no inner sleeve inside the product, which limits the radial compensation ability to a large extent, so it is generally only used to absorb or compensate the axial displacement of the pipeline (if a small amount of radial displacement is really needed in the piping system, it can be added when ordering Explain the maximum displacement of its diameter): the lateral displacement compensator (large tie rod) mainly absorbs the lateral displacement perpendicular to the axis of the compensator, and the small tie rod lateral displacement compensator is suitable for absorbing lateral displacement, and can also absorb axial, angular and any three Combination of displacement in one direction: hinge compensator (also called angular compensator). It is used in combination with two or three compensators (single hinge compensator has no compensation ability) to absorb lateral deformation in one-way plane, universal hinge (angular) compensator, which is matched by two or three When used, the deformation amount in the three-dimensional direction can be absorbed.
