Single Articulated Expansion Joints
Product Code: BFC/N
EMFLEX single articulated expansion joints (also known as single ‘untied’ or ‘tied’ flexible connectors) are used to absorb vibration in pumped systems and misalignment in pipework systems. They are usually installed at the pump suction and discharge connections. The tie rods prevent elongation due to the internal pressure thrust. The units are not intended to absorb vibration and misalignment simultaneously. Axial thrust must not be applied to these units, for example when pipework is mounted vertically from the unit. In this situation the pipework should be supported using spring supports.

Material Specifications
Bellows and internal sleeve are stainless steel. For steel service the flanges and tie rods are carbon steel. For copper service van-stone ends are stainless steel; backing flanges and tie rods are carbon steel.
Design Consideration
Single tied flexible connectors are used on high temperature pumps etc where conventional rubber flexible connectors do not have sufficient temperature capability (i.e. above 100ºC). They are usefully employed to relieve stresses on boiler crown valves and other vulnerable plant connection points.

Our EMFLEX Stainless Steel Expansion Joints are single articulated and come ‘tied’ or ‘untied’ to meet the requirements of your pipework systems. This product is used to solve issues caused by plant machinery, such as pumps, through absorbing movements that may otherwise damage pipework. It’s important to note that this product is not to be confused with our thermal expansion bellows, which cater for thermal movements in pipework.
To learn more about this product, simply explore the data sheets provided or get in contact with one of our experts to receive your free enquiry for any project.
