Angular Expansion Joints
Product Code: BHF/N
EMFLEX angular expansion joints are effectively a hinged bend in the pipeline and allow the pipe to bend through an angle in one plane only of up to +/-6 degrees. These units are pressure restrained, being fitted with hinges, so they impose only small forces within the system and light anchors are sufficient. The main applications are where large movements have to be accommodated in the piping system or where it is impossible to fit heavy anchors.

Material Specifications
Bellows and internal sleeve are stainless steel.
For steel service the flanges and hinges are carbon steel.
For copper service van-stone ends are stainless steel, backing flanges and hinges are carbon steel.
Design Consideration:
Force for maximum deflection is based on two joints with a distance of one metre between the hinge pins of the joints.
Maximum angular movement of each joint is +/- 6 degrees.
