Custom Variable Boiler Spring Assemblies
Piping Technology & Products, Inc. recently custom designed and fabricated 63 variable spring assemblies used to support a boiler in a power plant. Three sets of custom springs were designed for this project. The first group measures 14 x 14 x 17 1/8 and can support 45,000 lbs. per inch. The next group can support up to 28,000 lbs. per inch and measures 16 x 16 x 17 11/16. The third group measures 15 x 15 x 17 9/16 and can support 38,000 lbs. per inch. The coils in the assembly are made from 2 15/16 diameter coil with 2 3/4 or 3 active coils.
The variable spring assemblies are carbon steel with an inorganic zinc primer finish. The spring coils are A4161-H material with a neoprene exterior coating. Each spring coil was tested to insure the wire diameter, coil height and spring rates met customer specifications.
