Is it practical to try to design a variable spring support or constant spring support for travel less than 0.1″?

What does the hot or cold setting mean on a constant spring support?

November 2, 2010

The “cold” setting on a constant spring support refers to the location of the pipe at the installed position. The “hot” setting refers to the design location of the pipe at the operating position. In general, prior to installation, all spring supports are set at the “cold” setting.

What is the difference between a constant spring and a variable spring?

Variable springs always must have a difference in load between the hot and cold settings. Whereas in constant springs, the load remains consistent. Additionally, in general, constant springs can provide for a higher amount of travel. (Read More in our Technical Bulletin section)
