Pressure Balanced Type

PRESSURE BALANCED EXPANSION JOINTS

A Pressure Balanced Expansion Joint is designed to absorb axial movement and lateral deflection, while absorbing pressure thrust. This is achieved by means of tie rod restraints that connect a line bellows with an opposed balanced bellows also subjected to line pressure. Generally, to use bellows type of expansion joint, It is needed to install fixed point that receive thrust force of internal pressure. In case of large diameter and high pressure, it is difficult to install fixed point according to the place. You can use Pressure Balanced type expansion joint in this case and you can save expense of installation of fixed point. This type is classified into S type , T-type, L-type
