METAL EXPANSION JOINT
Externally Pressurized Type
H > Product > Metal Expansion Joint > Special Design > Externally Pressurized Type
SummaryExternally pressurized expansion joints are suited for piping systems that require large amounts of axial movement. In externally pressurized expansion joints, the bellows elements are arranged so that the media flow is on the external surface of the bellows. Externally pressurizing the bellows eliminates pressure instability as a limitation to the design and permits the absorption of large amounts of axial expansion.
Features· Ensure pressure stability
Types of Movement· Axial compression or extension
