hi

Dear piping stress experts..

I have one question regarding rigid strut.

can we use rigid strut in compression?

hi

can anyone tell me
what is the difference between flexible hose & expansion joint?

can we have any practicle application of flexible hose?

can I get some material on it?

thanks.

Hi Shamaliabhavin

Rigid strut used for sensitive equipment piping support ( Like compressor).
Because it offer exact zero gap support & friction less support that is not possible to achieve by conventional horizontal directional support.
Flexible hose & expansion bellow both use for as flexible pipe connection.
hose generally use for settlement & intermittent service. Expansion bellow use more widely as flexible connector.

Dear shr
first o all thank you for your response.

I am totally agree with you regarding the application of rigid strut

but
my question is that when we provide rigid strut to the line.

There are two possiblity that either strut will be in subjected to tension or compression in operation condition.

now can we use strut in compression?



one more thing is that can you show me any practical application or photo of flexible hose.

Hi Shamaliabhavin

Rigid Strut can be used for both tension & compression.
Should you need more clarification with some issues, can contact me in my mail ID.

Hi Shamaliabhavin

maybe it helps.

Dear RNM

thanks

but can you have any literature on it?

Hi Shamali

Well, I beg to differ from Mr. Habib regarding usage of struts in both tension & compression.

Struts are far better effective in tension than compression.
Though they can take some significant compressive loads but they are not better suited against buckling.

Correct me if I'm on the wrong side.

Thanks!!

SJ,

Express your opinion, that's fine, but don't make out that your opinion is fact. According to Wikipaedia ...

"A strut is a structural component designed to resist longitudinal compression."

A tension member would be termed a tie.

Fact .... adjustable struts are available from most pipe support spring and component vendors. These items are designed specifically to resist both compression and tension. They have many benefits including space saving over adjustable shoes etc, overall weight saving, the facility for accurate adjustment and stiffness once locked up.

Please remember the installation of the strut, if this is experienicng a thermal deflection in lateral, it won't be effective to resist the loads if end connections are not fixed.

Talking about facts...So here a few facts for your info:

a) When one says "I beg to differ" & "Correct me if I'm wrong" , he's not making a statement or being rude or putting forward a fact.

b) "Struts are far better effective in tension than compression." Does this mean , by any chance , I'm putting forward the idea that struts can't be used in compression?? I just said "far better effective" & not that they can't be used at all.

c)Wikipedia is not a stress engineer & the struts mention in their article are structural components used for designing of structure & not piping struts used as special pipe supports.

& last but most important fact

d) This a platform where users are intended to help each other & not to degrade someone or just to counter other views by looking into wikipedia.


I guess I've made myself clear to you!!!


Thanks,

Keep Smiling,

SJ,

You said .... " Correct me if I'm on the wrong side." You were wrong. I corrected you.

A strut (be it a 'piping' strut or a 'structural' strut) can be designed for any compressive load and be perfectly resistant to buckling with a little common sense and application of Euler's theory.

No need to get grumpy. This is indeed a forum for opinions, but if an opinion is misleading then it is not helpful.
