This week’s featured product is a hinged universal expansion joint and duct work assembly custom-designed for an exhaust duct application in a power plant in Kenya. The hinge hardware was fabricated from carbon steel, while the rest of the unit was fabricated from 316 stainless steel with Inconel 625 bellows. An F-type variable spring was also provided for this project and will be used to support the center spool between the two elbows. This duct work and expansion joint combo is 36″ in diameter, and the distance between the centerline of the two 90-degree elbows is 240″. It is designed for 20 PSIG at 115°F and 1/2 degree of angular movement. The entire assembly was 100% dye-penetrant tested, and a soap and air test was performed prior to shipment.
