Re: SOFTWARE FOR PIPE THICKNESS CALC
- Under 5 minutes. The wall thickness is 1.37 in. based on corr
all. of .05. I even have the class rating and the applicable WPS
plus the branch table using our PIping Spec. If branch is included,
i can tell wether a pad is needed or not. Add few more minutes, full
purchase spec plus NDE/test req'd is also no big deal.
- Using a programmable calc, the min. wall thick can be figure
under 5 min. included in the process is getting the values of the
allow stress in Table A-1 of B31.3 (17.5 ksi) and the OD (10.75)
from Tables P-1 Piping Guide. The CA, mill tolerance and others are
already part of the eq.
- Using MS Excel, much quicker.
- Typing the response, takes longer.
