U-Type Constant Spring Supports Designed to Support Ducts in an Acid Plant

U-Type constant spring supports were designed to support ducts in an acid plant. The constants are fabricated from carbon steel, galvanized and painted for extra protection against corrosion. The U-type constants are designed to support piping from below. The base plate is 25-7/8″ wide and bolted directly to the top of the steel or floor. Thep assemblies measure 84″ in length and 22-1/2″ in height. They only have vertical movement subjected by 6-1/2″ total upwards travel and are capable of supporting a 13,489 lb. load. The constants underwent standard spring testing prior to shipment.
