Piping Technology & Products, Inc. specially designed and fabricated four hundred 100-C, vertical constant load hangers for a plastics plant in Texas. The constants will be used to support a furnace standing three levels high.

In the plant, thirteen single beams confined to limited space will each hang thirty constants, therefore PT&P engineers were required to design the constants to weigh less than 150 pounds. The 136-pound constants with travels of 10 inches upward and a supporting load of 950 pounds, are 33 7/8" in height and 8 7/8" in width. They are also supplied with shop prime, painted finish to safeguard against the extremely hot temperatures of the furnace area. In order to insure quality and proper operations of the constants, a prototype was built and tested to MSS standards.
