42″ Diameter Neoprene Fabric Expansion Joint for a Generator Cooling Fan in a Power Plant

September 12, 2011

This neoprene fabric expansion joint is 42″ I.D. by 7-3/4″ face-to-face and is designed for a generator cooling fan in a power plant. The angle frame ends are fabricated from carbon steel, and the neoprene fabric belt is fastened to the angle flanges by two stainless steel clamps. The expansion joint absorbs vibration between the air supply duct and the cooling fan. A 100% dye-penetrant exam was performed on the welds of the angle iron flanges prior to shipping to the customer ahead of schedule.
