In-Line Pressure Balanced Expansion Joints for Combined Cycle Power Plant in UAE

MACOGA is the global leader in design and manufacturing of Expansion Joints for Power Generating Plants.

Our Expansion Joints are used by major EPC companies in the power sector, plant engineering contractors, power producers and plant owners, manufacturers of turbines and boilers for power generation across the globe.

On this occasion we have successfully designed, manufactured and tested three DN 1800 Pressure Expansion Joints for the seawater circulation (cooling) pumps of a natural gas-fired Combined Cycle Thermal Power Plant in the United Arab Emirates.

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.

Highlights of the Expansion Joints supplied:

• Rubber In-Line Pressure Balanced MPB-I Series
• Bellows materials: EPDM + Reinforcement fabric
• Size: DN 1800 mm
• Design Pressure: 6 Barg/F.V.
• Test Pressure: 9 Barg
• Design Temperature: +60 °C

With thousands of units installed and operating successfully in power plants around the world, MACOGA Expansion Joints are the benchmark in the power generation industry.
