Door flange is a precision-machined sealing interface component for vacuum chamber doors, ensuring hermetic isolation and structural integrity in industrial vacuum systems.
A door flange is a critical sealing component in vacuum sealed door systems, typically consisting of a flat, machined metal ring with precisely drilled bolt holes and a sealing groove. It serves as the mating surface between the vacuum chamber door and the chamber body, creating a vacuum-tight seal when compressed with a gasket or O-ring. The flange must maintain dimensional stability under vacuum pressure differentials and thermal cycling while providing a reliable mechanical connection.

KF (Klein Flange) uses a clamp and O-ring system for quick connections in medium vacuum applications, while ISO flanges use bolted connections with metal gaskets for high and ultra-high vacuum systems requiring superior sealing performance.
Elastomeric O-rings typically require replacement every 6-12 months depending on usage frequency and vacuum cycling, while metal gaskets can last several years but must be inspected for deformation during each maintenance cycle.
