Welded Bellows


Welded Bellows


  • Overview

Edge-Welded Bellows, also known as welded plate bellows, and welded diaphragm bellows, are essential engineered components in ultra-high vacuum and high pressure sealing applications. Their primary function is to compensate for system vacuum and pressure differentials during normal and upset operations. Secondary functions include mechanical sealing, vibration, isolation, compensation for relative movement between pipe sections, and reduction in forces and induced moments at various connections. In the bellows industry, edge welded bellows stand out in their ability to control large amounts of motion precisely and repeatedly.
