Hello,
We have following case:
1. Pipe - PPsEL: polypropylene electro-conductive & self-extinguishable.
2. Pressure rating PN 10 and PN 16
3. Working pressure: Maximum - 10 bar
Minimum - -65 bar
My question is: Is there any standard for this or Any formula to calculate the required thickness of the pipe to withstand Maximum and minimum pressure?
Advance thanks!
 
Well max pressure seems to have been worked out if you can buy PN10 and PN 16 rated pipe.

Is that min minus 65 bar??

Is this pipe empty at the bottom of the ocean??

I don't think PP pipe will withstand that level of external pressure.

In general PE and PP pipe really doesn't like external pressure.

A few more technical notes ( material design codes used, material strengths) and bit more background would help a lot.

This stuff?

Remember - More details = better answers
Also: If you get a response it's polite to respond to it.
 
Sorry the negative pressure is minus 65mbar(-65mbar). *-65 bar was typo mistake*
The pipe is above ground level maximum of 10m height and exposed to atmospheric pressure and it carries gases
For deciding the pipe specifications we are trying to see is there any standards and for that reason we are seeking help in this forum
We only have info about pipe material: PPs-EL
And thanks for the fast response!
