Elbow Pressure Balanced Expansion Joints for Supercritical Power Plant in North Africa
Two Elbow Pressure Balanced DN 2000 (80”) and 6530 mm (257”) long have been successfully designed, manufactured, tested and shipped for a Power Plant in North Africa.
A pressure balanced expansion joint accommodates axial and lateral movements and counteracts the bellows pressure thrust. An additional bellows is incorporated into the unit and is subject to the line pressure to generate a force equal and opposite to that on the main bellows. Tying these bellows together neutralises the pressure load on the unit.
