Hi,
I am working on FRP Piping system using UKOOA Standard.
AS Per Technical Reference manual
Code Stress Code Allowable
sab (f2 /r) + PDm / (4t) < (f1 f2 LTHS) / 2.0
Where:
P = design pressure
Dm = pipe mean diameter
t = pipe wall thickness
As per above equation i have some question.
1)How can i calculate the value of LTHS?
2)If i want to qualify system in occasional condition.
As per below Load cases
W (f2 = 0.67)
W + P1 (f2 = 0.67)
W + P1 + T1 (f2 = 0.83)
W + P1 + U1 (f2 = 0.89)
W + P1 + U2 (f2 = 0.89)
W + P1 – U1 (f2 = 0.89)
W + P1 – U2 (f2 = 0.89)
How can i define differnt f2 in CaesarII?
3)Should i have to check seggregated occassional case?
4)as per attached caesar file occasional code allowable is 1.0*Sh it should be 1.33*sh.
we have taken reference from below discussion
