Multi-ply oval expansion joint

Multi-ply oval expansion joints for a customer whose main focus is within the Fuel cell industry and is a leading player in marine applications. The challenge of this project was to provide a solution meeting their engineering and detailed requirement for their specially developed system.

Thanks to the kompaflex experienced engineering team we were able to design a unique technical solution that fits into the existing system and meets all requirements. The multi-ply oval expansion joints are entirely made of the material 1.4835, a heat resistant austenitic chrome-nickel steel for high temperature applications.
