Hi folks,

I am wondering if anyone has a spring rate table for F&S/Central variable springs.

The reason I am looking is I have to model about 100 existing springs on a 1975-era piping system, and all the data I have are F&S/Central model numbers, hot loads, cold loads, and displacements. CAESAR needs cold load and spring rate to input pre-defined hangers. I know I can calculate the spring rate from the data given; however it appears the displacements were rounded off to the nearest 1/16" or 1/8", so I don't always get "even" spring rates when I back-calculate them. So being able to look them up in a table would be much easier.

Alternately, does anyone know the Grinnell model cross-references for F&S/Central types FSC-1, FSC-2, FSC-4, and FSC-6?

Any help would be appreciated.

Cheers,

- Matt
