Metal Externally Pressurized Expansion Joint

Flexibel07 Oct, 2025Business

The Metallic Externally Pressurized Expansion Joint uses a unique design in which the process pressure is applied externally to the bellows element rather than internally. This allows the joint to absorb long axial movements without the risk of squirm, buckling, or premature fatigue. Typically supplied with butt weld ends or flanged connections, these joints are well-suited for long pipeline runs requiring high reliability and stability under pressure.
