thread292-246231: B31.3 Thermal stresses
I am not sure whether I have determined the correct anchor distance U in my calculations to check the requirement for Flexibility Analysis as per 319.4.
Question: In determining U (straight line distance from anchor to anchor), does it mean the diagonal distance between anchors in a rolling pipe?
What I did is use the simple space phytagorian (c2 = a2+b2+h2) to calculate the distance. Can anyone tell me if my procedure is correct?
Thanks in advance.

x=2363 mm
y=3226 mm
z=1488 mm
This comes out after algebraically adding all the piping segments on the pipe spool roll being considered, done for each corresponding axis.
I simply assumed that U = SQRT(x^2+y^2+z^2)= 4227 mm
To be use on Flexibility Analysis check through equation (16) in 319.4.1.
Any comment on this?
