Externally pressurized pipe expansion joints
Externally Pressurized (X-Flex) Pipe Expansion Joint
Externally pressurized pipe expansion joints, also known as x-flex expansion joints, are suited for piping systems that require large amounts of axial compression or extension. In externally pressurized pipe 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.
