Externally Pressurized Expansion Joint



Externally Pressurized Expansion Joints have a heavy duty packless design that enables this product to accommodate large amounts of axial motion at high pressure with the risk of bellows squirm. Limited to axial movement only, the bellows is fully enclosed within an outer shell that is constructed of standard weight pipe, offering the highest degree of protection for the bellows and personnel. External insulation may be added directly over the outer shell. This expansion joint design also permits direct burial.
