Fully Articulated Expansion Joints
Product Code: BLF/N
EMFLEX fully articulated expansion joints consist of two bellows connected by a piece of pipe which permits a pipeline to move in any lateral direction, with each bellows moving through an angle of up to +/-6 degrees. These units are pressure restrained, being fitted with tie-rods, 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.
