Piping Technology and Products, Inc. custom designed and manufactured variable springs to be used in conjunction with a rod and clevis assembly for a power plant in West Virginia. Since the operating loads specified by the customer were greater than the maximum loads for the largest PT&P spring, custom units needed to be built for this application. The springs were fabricated using a large spring coil, normally only used in constant spring assemblies. The spring is 20 1/2″ in diameter and has a standing height of 51″. All components of the pipe hanger assembly were made from carbon steel and were supplied with a hot-dipped galvanized finish. The spring is 20 1/2″ in diameter and has a standing height of 51″. The rods will be attached to type A variable springs designed to support loads from 850 lbs. to 13,300 lbs. Manufactured from A-36 carbon steel, the rods are 3/4″ to 2″ in diameter and range in length from 68″ to 95″.
To prevent contamination at high temperatures, a non-galvanized finish was applied to the rods per customer’s request. Prior to delivery, a 100% dye-penetrant test was preformed to ensure quality. The variable springs were tested in the load cell to insure proper operation and also to set the cold load to the specifications as provided by the customer.
