Composite three-way expansion joints in the cement industry2024-04-08 13:45:16: The compound three-way expansion joint in the cement industry refers to a flexible component that can effectively compensate for axial deformation. For example, the expansion joint welded on the fixed tube plate heat exchanger shell has high axial flexibility and is prone to deformation. It can compensate for the thermal expansion difference caused by different wall temperatures between the tube and shell, reduce their axial load, and thus reduce the temperature difference stress of the tube, tube plate, and shell, avoiding strength damage, instability damage, and tube pull-out damage. There are many types of expansion joints, including waveform, ring plate welding, and flange connection. Among them, professional expansion joints in the cement industry are most widely used, while ring plate welding expansion joints are only suitable for atmospheric or low-pressure situations....

Double straight pipe bypass pressure balanced expansion joint2024-04-08 13:28:53: The double bypass pressure balanced corrugated expansion joint adopts the same specification of corrugated pipe, which has small volume, low cost, good guidance, and good stability. Mainly used to absorb axial displacement and balance the pressure thrust of corrugated pipes, the internal pressure thrust load is balanced and borne by its own components, and is used in situations where large thrust is not allowed....

Single type straight pipe bypass pressure balanced expansion joint2024-04-08 13:15:56: A single type straight pipe bypass pressure balanced expansion joint is a flexible component composed of two corrugated elements with identical geometric parameters and two or adjacent pipes or equipment connected to connecting pipes (or flanges) and heads.Introduction: Mainly used for compensating axial expansion in straight pipe sections. Compensators can balance the pressure and thrust of pipelines, and fixed pipe supports may not consider bearing the pressure and thrust of pipelines.Main features: The expansion joint has the ability to absorb internal pressure and thrust, and has good guidance. The product has small stiffness and small external dimensions....

Curved tube pressure balanced expansion joint2024-04-08 13:11:11: Curved tube pressure balanced corrugated expansion joints, also known as curved tube pressure balanced compensators, are installed on pipelines at bends or in spaces connected to equipment. Curved tube pressure balanced corrugated expansion energy-saving compensation for axial and lateral displacement, without generating internal pressure thrust on the pipeline system.The curved tube pressure balanced expansion joint adopts an elbow structure, on the one hand, to reduce the pressure of the system; On the other hand, in order to prevent high-speed airflow from eroding the balanced expansion joint. This type of expansion joint cannot absorb axial and lateral thermal displacement reactions from the piping system....
