These rubber expansion bellows are flexible connectors that absorb movement, vibration and thermal expansion in piping systems. ChangYuan Flex Co. rubber expansion bellows are engineered for high performance and long life in the toughest environments. These bellows are made of high quality elastomers reinforced with several plies of high-Tensile polyester tire cord and are chemical, temperature and mechanically resistant. A proprietary CY-Flex ™ compound developed by ChangYuan Flex Co. ensures better weather resistance   and elasticity to provide maximum flexibility without compromising structural integrity.

These rubber expansion bellows have a wide application in HVAC / water treatment / power generation and chemical processing industries. ChangYuan Flex Company rubber expansion bellows have an arch-type construction to maximize movement absorption capability and reduce stress on connected piping system. This innovative design together with integral flange for secure installation ensure leak-free operation and lower system failure risk. Their service life is further extended by the company’s CYAAL technology, which makes these bellows an economical solution for industrial use in the long term.

To meet changing industry requirements, ChangYuan Flex Co. introduced several advanced features to their rubber expansion bellows. Sediment accumulation is prevented by a self cleaning convolution design reducing maintenance requirements and increasing system efficiency. For outdoor applications a UV/ozone resistant outside layer provides additional environmental protection. Moreover, it offers an integrated smart sensor option for real-time performance monitoring allowing facility managers to prevent problems from becoming worse. This innovation spirit, together with strict quality control and international standard compliance make ChangYuan Flex Co. rubber expansion bellows the first choice for industries needing reliable, high-performance flexible connectors.
