Special Vertical Type E Constant Spring Supports

Piping Technology & Products, Inc. designed and manufactured special vertical type E constant spring supports for a power plant. These were designed and installed as pairs in a configuration similar to the typical G type constants. The advantage of using a pair of the special E rather than the conventional G type is that the total width is smaller as can be seen in the photo above.

The constants were designed to support loads from 5,730 lbs to 10,690 lbs. They were fabricated from A36 Carbon steel. The dimensions of the individual constants are 60" high, 16 1/2" long, and 14" in wide. The size of the supported pipe determined the width of the assembly. As with all constants built by PT&P, they were tested to verify that standard specifications for variation of load over the full range of travel were met.

U-Type and F-Type Constant Spring Supports

F-Type Constants

Piping Technology & Products, Inc. designed, manufactured and delivered a total of 8 constants to a power plant in Mexico. The designs consisted of 4 Horizontal U-Types Upthrust (Figure 1) and 4 Vertical F-Types (Figure 2) that are to support 24-inch diameter pipes. Each consisted of different sizes. The constants are designed for loads of 2,839 lbs. to 8,963 lbs., for Total Travels ranging from 7 to 3 inches. Constants were painted CZ-11 per customer request.

Big-Ton D and Big-Ton T Upthrust Constants

PT&P custom designed and built four Big Ton D Upthrust Constants(figure 1) and two pairs of Big Ton T Upthrust Constants (figure 2) for a global engineering & construction company.

These upthrust constants are installed at a Petrochemical Plant in Siberia. Due to space limitation, the Big Ton D Upthrust Constants and Big Ton T Upthrust Constants were designed for a total travel of 5" and 4" respectively. The Big Ton D Upthrust Constants were also designed for a load of 50,022 Ibs with a height of 26 inches. The Big Ton T Upthrust Constants with a height of 16.5" were designed for 75,000 Ibs, and 67,464 Ibs respectively.
