High Pressure Flange Connected Axial Sleeve Expansion Compensator for District Heating and Water Pipelines

This high pressure flange connected axial sleeve expansion compensator is a sliding thermal compensation device specially developed for district heating, hot water circulation and water transmission pipeline systems. It mainly absorbs and compensates the axial thermal elongation and contraction of pipelines caused by temperature variation, so as to eliminate harmful thermal stress inside the pipeline and prevent pipeline deformation, cracking and connection failure. Adopting flange connection form, it can be quickly matched with supporting pipeline flanges, bringing great convenience for field installation, disassembly, inspection and later maintenance. The product is equipped with optimized packing sealing assembly, which has good wear resistance and sealing stability under high pressure working conditions. It features low sliding friction, stable operation, compact and reasonable overall structure, and strong adaptability to medium temperature changes. It is suitable for medium such as hot water and clean water in heating networks and water supply pipelines. Strictly manufactured in accordance with relevant pipeline equipment standards, this sleeve compensator can keep reliable sealing performance for a long time, effectively extend the service life of the whole piping system, and is widely applied in urban central heating projects, industrial hot water pipelines and municipal water delivery systems.
