Screwed Axial Expansion Joints
Product Code: BATN
EMFLEX axial expansion joints with screwed ends are used to absorb thermal expansion in straight pipelines. They are installed in the pipeline and anchors are required to withstand the forces set up in the pipeline due mainly to the internal pressure in the bellows. Correct alignment of the pipeline is essential with this type of expansion joint and proper pipe alignment guides are recommended. Only one axial expansion joint should be installed between each pair of anchors.
