Installation Of EJMA 304 Stainless Steel Metal Bellows Expansion Joint Pipe And Container

The expansion and contraction of the corrugated expansion joint is mainly realized by the bellows. The function and strength design of the corrugated expansion joint is mainly the design of the bellows. The different designs and combinations of the bellows can make the bellows stretch, Compress or bend to form corrugated expansion joints in three basic forms: axial, lateral and angular.

The elbow force balance corrugated expansion joint is used for the connection between the equipment and the equipment. Its function is to compensate the thermal expansion of the pipeline between the two equipment, reduce the force generated by the installation error on the equipment, and facilitate the installation. The use of elbow force balance type corrugated expansion energy saving makes the equipment not affected by the blind plate force generated by the internal pressure, improves the force condition of the equipment, and the equipment is easy to fix. The corrugated expansion joint is used as a flexible coupling pipe for the pump to be applied to the inlet and outlet pipes of the pump. General-purpose (namely universal) expansion joints are installed on the inlet and outlet pipes of the pump to compensate for the thermal expansion of the pipeline, reduce the thrust of the pipeline thermal expansion on the pump, or absorb the vibration generated by the pump operation.

Due to various constraints, it is quite complicated, but for any complex piping system, several fixing brackets can be selected to choose different settings at different positions, and they can be divided into several relatively simple separate pipe sections, "Z" pipe sections and "∏" type pipe section, etc., and determine the deformation and compensation amount of each pipe section respectively. Because of the many types of compensators, the correct selection is very important. Therefore, the overall design of the piping system should fully consider the pipeline The design and comprehensive consideration of the shape and configuration of the compensator and the design of the orientation and support system (including fixed pipe racks, guided sliding pipe racks, etc.) show a safe, reasonable, applicable and economical best combination.

The corrugated pipe compensator is a flexible element with a corrugated pipe as the core, and is compensated in three directions: axial, lateral and angular directions on the pipeline. The axial compensator is to reduce the self-excitation 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 given 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 A combination of displacement in two directions: hinge compensator (also called angular compensator). It is used with two or three compensators (a single hinge compensator has no compensation capability) to absorb the lateral deformation in a one-way plane. The universal hinge (angular) compensator consists of two or three matching It can absorb the deformation in three-dimensional direction.
