FRP/GRE piping

Hi all,
Can any one explain me what is the meaning of "2:1 pressure condition or loading condition"? (this term is related to FRP/GRE piping)

What is the ratio of hoop to longitudinal pressure stress?

oh, got it. Then what is "0:1 condition"?

thank you for quick reply anindya.

If you don't know this stuff, are you sure it's wise to do FRP pipe stress analysis?
FRP is a completely different material in comparison with steel. Also it's much more difficult to get the correct material properties from the supplier.

0:1 condition btw is no hoop stress and full axial stress.

Yes you are right, its not wise to do FRP analysis with out knowing the basics. I dint tell that i am doing FRP stress analysis. I am learning the basics of it; anyway, thanks for reply.

As this forum is (mainly) intended to help people out with the use of CII I guessed you were doing a FRP analysis.
Glad I could help though. :-)
