Try to calculate the thickness schedule of the Pipe
ASTM A 335 P22 for design pressure of 30 bar at 400C
design temp, Pipe size being DN 250 (10 inch NB) to be
designed as per ASME B31.3.
Check if you had been able to answer in 5 minutes.
This is the question I pose to piping engineers in my
trg program, and then they start asking for code,
allowable stress values, pipe schedule chart etc.
Getting all this references is a job, which is done by
the demo software in few minutes, only you have the
loaded software AutoPIPE demo on your computer to
immediately start and get the answer.
I have to put the lengths in X-Y space for a model to
make the software effective to get you quich hoop
stress check. Unless one tries he may not appreciate
the comments I made.
