PTFE expansion joints

PTFEl expansion joints are used to reduce the vibration from pumps in very narrow spaces, to take over tension due to thermal and mechanical expansions in pipes. They are very efficient in agressive environnement and can be equipped with non metallic flanges to resist also to the ambiant acidity.
With a machined bellow, the PTFE expansion joint can be mounted under scales. They are so flexible that they won't influence in  the weight process.
