HI MARIOG,

THANK YOU VERY MUCH FOR YOUR QUICK REPLY.

YES I NEED ASME B31Ea-2010. REASON IS WHEN I REFERING CAESAR USER GUIDE OF 2011(VERSION)I FOUND BELOW STATEMENT IN PAGE 1034.

"Rp = Component response modification factor, from Table 13.6-1

= 12.0 for "Piping in accordance with ASME B31... with joints made by welding or brazing"; values range as low as 3.0 for other joints and for less ductile materials."

BUT NOW AS PER YOUR REPLY IT SHOULD BE BELOW 3.5. WHICH ONE IS RIGHT APPROCH. IS THE GUIDE IS WRONG CONCEPT?

I AM REALY CONFUSED.
