Expansion Joint, Twin Sphere FAQs
1. for Expansion Joints, Single Sphere, Twin Sphere, Which One is Better?
Both of them could absorb vibration and noise in the pipelines. However, twin sphere expansion joints could provide more pipeline motion absorption capacity, and even higher noise and vibration control efficiency. Furthermore, twin sphere expansion joints can withstand the most stringent pipe system configuration. They could provide better axial compression or extension, lateral deflection and angular motion.
We trust that through our continued effort and steady growth, Hebei Leading will become one of the premier flanges, butterfly valves manufacturing company in the world, and an all-range provider in the flow control field.
