what is the maximum force on a support?

once the stress calculation is completed, it is possible to have supports that have very high loads.

For example a 4-inch pipe with a 4000N rest support.

what is the maximum value that a shoe can support before damaging the pipe?
do you have any reference tables?

I imagine that an FEA analysis should be made based on the type of support (direct support on the beam, 300mm long shoe, 400mm long shoe, ...) and on pipe schedule. But for an Std. schedule pipe, which values do you think are acceptable for lines of 2 ", 3", 4 ", 6", 8 "?

Some company have a pipe support standard with allowable load table given for a specific size range and thickness range.

This webinar from PRG is very informative for your query.

High cyclic loads (fatigue) and high temperature application (elastic follow-up) combine with highly corrosive fluid, is normally where you will exercise caution.

Warm Regards,

do you have an allowable table?

It's worth noting that the casual analysis will not consider the stiffness of a shoe, or of a beam.

The loads as reported by CAESAR will often drop tremendously... by a magnitude of 5 or 20, even, as it'll allow CAESAR to distribute the loads amongst several supports.

Consequently, you also should not be relying on supports having 1e12 lb/in to rescue your piping or nozzles.

Hi vermacio,

It is proprietary by the company.

Warm Regards,

i don't ask for you to post the proprietary company standard. i ask only if you can read it and tell me max values for 2", 3", 4", 6", 8", 10".

Hi Vermaccio,

You can use the help of Google. I found one in public.

Actually, I dealt with pipe supports on a case by case basis and not really using the company standard since my current company don't have one. It was my previous company that I see those tables.

Unfortunately, I don't have a copy of it.

You can use classical method and if you have FEA software in-house of your company better to explore it so that your approach will be general.

Sometimes, other company have a dedicated team designing pipe supports. But in my current company the set-up is not like that. So I have to rely on my own using the available tools at hand. Fortunately, FEA software is available. But if FEA is not available then you can always use the classic method as long as client approves it.

Warm Regards,

"available tools at hand":
which ones?
