    Calculating t/min on economizer tubes.

    So go off of PG-26 and represent this as 1 correct? Since its not required for carbon steels? I'm sorry if I sound repeating I'm just trying to find the exact answer.

    Calculating t/min on economizer tubes.

    Okay the what would the w represent and where would I find that for the equation?

    Calculating t/min on economizer tubes.

    Thinking about it again. Since in Table PG-26 in ASME SEC I says carbon steels are exempt from this table should I leave "w" at 1?

    Calculating t/min on economizer tubes.

    I get the "w" from w being weld strength reduction factor in ASME SEC 1 PG-27.3. That exact tube being ERW sense its seam welded with no heat treatment nor 100% rt going by the MTR the reduction factor would be .85. In ASME SEC 2 Part D in the notes for that material G3 would call for that to be...

    Calculating t/min on economizer tubes.

    Also if you look at PG-27.4.4 "e"=0 for strength welded tubes which is what I'm doing. So in my equation I have "e" as "0"

    Calculating t/min on economizer tubes.

    Okay so how would I use "e" in my equation? I'm dealing with trying to get t/min for economizer tubes. How does PG-27.4.4 apply to figuring this? Also I've learned the "w" refers to weld efficiency which would be .85 according to ASME SEC II Part D Table 1A Notes for SA 178/A tubes.. Thanks for...

    Calculating t/min on economizer tubes.

    Guys I can't seem to find a correct answer after digging and searching for t-min on SA-178/A economizer tubes. I have the calculation from 2023 ASME SEC I (PG-27.2.1). This is what I have so far and I'm stuck. (P) Pressure=850PSIG (D) Diameter=2.00" OD (S) Stress=13,400 (According to ASME SEC...

    How to know exactly which filler metal?

    Hello everyone I'm newer to the QC side of things and just curious how to know exactly which filler rod to use for certain materials.. any help would be appreciated. Soo for instance if I'm welding P-8 to P-8 there's a whole list to use of filler metals. Me previously being a welder I just know...
