Flexatherm Expanllow Pvt. Ltd. Manufactures Inline Pressure Balance Expansion Joint. Flexatherm Expanllow Pvt. Ltd. Is an ISO 9001: 2008 certified company. The Inline Pressure Balance Expansion Joint is specially designed to absorb axial, lateral and angular deflection, while restraining the pressure thrust exerted by the internal pressure and without a change in direction of the piping. The pressure thrust is restrained by the tie rods arrangement, which connects the line bellows and the balancing bellows. This expansion joint is a constant volume system, so the Main Anchors can be designed as intermediate anchors, and function only to direct the thermal expansion of the pipe towards the expansion joint.
The Inline Pressure Balance Expansion Joint consist of two line bellows and a balancing bellow having effective area twice than that of line bellows. The line bellows absorb the axial and/or lateral movement while restraining the pressure thrust by the means of the tie devices interconnecting the balancing bellow, which is also subjected to the line pressure. Each bellows are designed to absorb the axial movement while the line bellows are designed to absorb the lateral deflections also.
Advantages of Inline Pressure Balance Expansion Joint are:
