Hi experts,
I’m calculating assembly torque values for 300#, A105 RTJ flange joint with A193-B7 bolting. I’m referring GP42-32 a British petroleum for calculations and values of variables. Calculation results show O-7 check fails thanks to equation O-6, for size 3,4,6 & 8. I’m not sure how to...
Hello,
I have numerous SS304 150# piping class with MDMT of -48.4 deg C. I’m planning to use SS304 stub ends per ASME B16.9 with LF2 CL.1 backing flange. Can I use this combination given lowest minimum permitted temperature for LF2 CL.1 is -45.6degC as per ASME B 31.3?
Hello experts,
Should I consider the formula provided in ASME B 31.3(304.2.1) for calculating wall thickness of ASME B 16.9 elbows which are manufactured say on mandrel? I did a WT check for for a particular case using 304.2.2 where I found that intrados thickness of LR(1.5D) ASME B 16.9 elbow...
Hello members,
1. I'm calculating WT to purchase A312-TP321H seamless pipes for design conditions 800°C at 3.5kg/cm2. For thk >3/8", ASME B31.3 mentions note 30 against it in Table A-1 which states "For temperatures above 538°C (1,000°F), these stress values
may be used only if the material has...

Hello members,
Can you kindly help me out with below query?
1. I have to calculate the WT for A358-321 CL.1 pipe at design conditions of 800degC at 49.7psig. Am I correct in understanding that value of W must be linearly interpolated from values in the row "Austenitic stainless grade 3xx and...

Hi experts, I am looking for some advise on on weldolets. The client line class specifies a weldolet for 72”x24” run-branch connection. Frankly speaking I have never such a big run size pipe nor such a size combination of weldolet. I’m wondering whether if it is a good idea to use a weldolet...
