Variable Spring Hanger Sizing

Could you explain why on your opinion the hot load -which is an external parameter - depends on the allowable stress x pipe wall area in axial direction.

If you want to learn some thing well you should clarify your thoughts and accept corrections if not you will use an equation but don't know what is the background of it and this is BAAAD.

Munney,

Because of your word usage and syntax, it is very difficult to understand your question.

To establish both a "hot load " and a "cold load" for a spring hanger, you must consider and evaluate the piping and support system as a whole.

This is typically done with a piping stress analysis program such as CEASAR-II There are many others, but C-II is the one most often stolen in the third world.

Both the hot and cold loads for the spring hanger are important as they are necessary for proper hanger installation and for initial evaluation when the system heats up for the first time.

The "hot load" of a variable spring hanger is the load that the hanger is providing WHEN THE PIPING IS IN THE HOT CONDITION.

Depending on the expansion of the system, the "hot load" could be greater than or less than the "cold load"

Tell us more details about your piping system and if there has been any detailed flexibility analysis performed.
