Super-alloy Inconel 625 Sylph-on Bellows Joint

Sylph-on Bellows Joint

Product Description

Engineered, custom-built Sylph-on bellows joint built for critical valve sealing duties. The bellows core is constructed from Inconel 625 superalloy, paired with ANSI-compliant 316 stainless steel flanges and 316 stainless steel valve stem shanks. This metal bellows unit is fabricated with high-fidelity laser welding and precision CNC machining, delivering robust performance under elevated-temperature and heavily corrosive service environments. Drawing-led OEM and ODM custom development is offered to match unique project requirements.
