Description
Externally Pressurized Expansion Joints are the perfect choice for large amounts of axial compression or extension.
TopFasterner can design externally pressurized metal bellows expansion joints with over 18” total axial movement capability.
Other benefits of an externally pressurized expansion joint are that they have a built-in guiding system eliminating the need for the first pipe guide in a piping run.
For steam applications, where usually a flow liner is required, externally pressurized expansion joint, due to its construction eliminates this requirement.
This type of metal expansion joint also incorporates an outer casing to contain the pressure which also protects the metal bellows from damage.
