PT&P custom designed and manufactured big ton constant spring supports w/ bronzphite® slide plates for a 400 KTA light oil for a processing and utilization unit at an oil refinery in China. A total of four constant assemblies were fabricated from carbon steel and hot-dipped galvanized for extra protection against corrosion. The bronze plate acts as the bearing surface, supporting heavy loads, while the graphite inserts provide a solid, oil-free sliding surface. They are designed for operating temperatures up to 750°F and an operating load of 187,393 lb., with 1-1/2″ total travel. Load and travel testing was performed prior to shipment.
