Excellent response barbara... new question... "is 12.5% of mill tolerance is thickness with corrosion allowance or without corrosion allowance?"
without ca
ANS...the mil tolerance is how it comes from the mill.IE COMES OFF THE PROVIDED MONIMAL MATERIAL SIZE....
the ca (CORROSION) is what occurs over time and is always taken off the remaining or available material for CALCULATING allowable pressure (or added to the final required calculated thickness)

*but generally all the warning messages are ignoring for analysis,.. DOESNT SOUND SO GOOD. -----Original Message-----

thanks for reply.
If warning message comes means our thickness is not enough for design pressure,but generally all the warning messages are ignoring for analysis,so
after warning message is it necessary to change our pipe thickness? and one more thing is 12.5% of mill tolerance is thickness with corrosion allowance or without corrosion allowance? anyone can explain briefly,
