Externally Pressurized Expansion Joints

TWIN CITY HOSE Externally Pressurized Expansion Joints DESIGN

Joints are rated for 300 PSIG working pressure up to 650º F. Axial movements of 4" compression and 3/4" extension (short) or 8" compression and 1-1/2" extension (long).

Externally Pressurized Expansion Joints are designed with external pressure to the bellows along with an internal guide ring which eliminates bellows squirm; they have an internal liner as part of their integral design to eliminate flow induced vibrations along with an internal limit stop to eliminate over-extension of the bellows. They are compact when compared to a pipe loop, which saves valuable space. Simplicity of this proven design eliminates packing, requires no maintenance, will demonstrate long-life, dependability and is easy to insulate.
