Request Opinions on the Design Code for the following Lines connected to the X-Mas tree of a Gas Well Head:
1) Wing Valve to choke Valve.
2) Choke Valve to Pad Limit Valve.
3) Pad Limit valve to U/G.
4) Well Head Kill Line.
Thanks in advance for sharing your thoughts.
Jeffbru:
Sorry for a very late reply. I got busy in a very tight scheduled project which is not over yet.
I can understand your feelings as I have been through it...
An override of my system inputs for your indicated values:
R/t=1173
a/R=0.008
L/2a=1
gives me the following values...
I faced the same problem.
Some of the values (stiffness coefficients) given in the example are wrong. You can check yourself by careful manual plotting.
There are not just two L/2a but also only three a/R.
I have done curve fitting for intermediate a/Rs.
I used linear interpolations with...
I used Linear.
I spent more than two months in using different approaches later had to do the curve fitting for curves between the ones given in the figures.
Best of luck.
Friends,
I am a piping engineer and am working on a software for evaluating Nozzles connected to API-650 based tanks.
Anybody worked on developing the equations for various curves?
It will be useful if some body could share.
BR,
