Modeling Exp. Joint for Acid Weak, good assumption ?

drakkkko · May 26, 2015

Hello everyone,

Can anyone give a hand with a Expansion joint assumption ?. This exp Joints is for Acid Weak (concentration of 25%), at 49°C (120°F), pipes diam= 6".
As you know Caesar ask for stiffness And I looked for some brichure with stiffness data but I couldn't find anything.

So I may take other brochure with other fluids such strong acid. what is the worst scenario or conservative assumtion ¿ bigger stifness ?

Thanks in advance!!

An accident waiting to happen ?

What is the relevance of 'weak acid' if you are looking for EJ stiffness data ?

Which EJ manufacturer are you using, and why don't you have access to full tecnical data ?

You are right , there's no relevance about weak acid with stiffness.
Those EJ, already exist, that's why I have to assume (communication with client it's very slow and almost inpossible for me). Manufacturer don't answer very fast or at all, because I'm not buying and just asking for data.

So my question to you is, ¿ do you have some idea how to approach this kind of assumption ? and repeat the question already written:
It is a conswrvative scenario assumtion a big stifness ?
