The double hinge expansion joint of the air-cooled island vacuum pipeline plays an important role in the system. This type of expansion joint mainly consists of a corrugated pipe, two sets of hinge plates connected to the end pipe, and a pair of pin shafts. It is usually used in groups of two or three to absorb lateral displacement in one or more directions in a single plane pipe system.
In the system, each expansion joint is constrained by its hinge plate, resulting in pure angular displacement. Each pair of hinge type expansion joints separated by the pipe section cooperate with each other and can absorb lateral displacement. The hinge plate of the expansion joint is usually used to bear all the pressure and thrust acting on the expansion joint, and can also be used to bear the weight of pipelines and equipment, wind loads, etc.
Specifically, the main function of the double hinge expansion joint is to compensate for the thermal expansion and contraction of the pipeline caused y temperature changes or mechanical vibrations. Through its unique structural design and working principle, the double hinge expansion joint can ffectively absorb and alleviate stress and displacement in the pipeline system, thereby protecting the stability and safety of the pipeline system.
Therefore, the application of double hinge expansion joints in air-cooled island vacuum pipeline systems can significantly improve the reliability and durability of the pipeline system, ensuring the normal operation and efficient performance of the entire system.
Overall, the double hinge expansion joint of the air cooling island vacuum pipeline is a key component to ensure the safe and stable operation of the pipeline system, which is of great significance for improving the performance and efficiency of the entire system.
