EASYFLEX braided building expansion joints are used to suppress vibration from pumps, to absorb intermittent lateral movement in pipelines and to compensate for subsidence when pipelines cross building movement lines. They must be installed at right angles to the direction of movement when installed in pipelines and close to the suction and discharge connections when used on pumps. They are not suitable for absorbing AXIAL movement, but are an alternative to articulated or angular expansion joints for low velocity applications.

Type EFBBF

For use on steel pipelines and is suitable for steam and hot water for heating. This unit has stainless steel hose and overbraiding with flanges of carbon steel.

Type EFBBFN

For use on copper pipelines and is suitable for condensate and domestic hot water. This unit has stainless steel hose and overbraiding with ends having stainless steel to all internal surfaces. Hence, this unit is also suitable for potable water.

Design Consideration

The overall lengths in the table are for flexing applications. When using these units on static applications, for example subsidence, they will absorb 1.5 times the lateral movements shown.

Material Specifications

Convoluted hose and overbraid are stainless steel.
For steel service the flanges are carbon steel.
For copper service all wetted surfaces are stainless steel.
