Multi-axis expansion joint

　　The expansion joint is a key device for ensuring axial displacement compensation in pipeline systems. It mainly consists of multiple bellows, intermediate pipes, and connecting flanges. Its working principle is based on the expansion and contraction characteristics of the bellows. When the pipeline experiences axial displacement due to temperature changes or pressure fluctuations, the bellows can expand or compress accordingly, effectively absorbing the displacement and preventing damage to the pipeline due to stress concentration. This expansion joint has a large compensation capacity and can adapt to the expansion and contraction needs of long-distance pipelines. It is made of high-strength materials, providing good compressive strength and corrosion resistance. It is widely used in pipeline systems in industries such as heating, petrochemicals, and electricity, ensuring the safe and stable operation of pipelines, reducing maintenance costs, and extending the service life of pipelines. It is an important component for maintaining the normal operation of pipeline systems.
