Thanks to all. Rick

B7/B16 will do fine under section 8, but that is not the question here.

725 psi/800 F

I am attempting a boiler repair requiring bolts holding together a category H fitting designed to Section I.

Where are allowable stresses found for Section I bolting materials? Table 3, Section II part D does not appear to include Section I.

Where are allowable bolt stress values found for Section 1 equipment? Table 3 of Section II does not appear to include Section 1 equip.

Yes I have read A672 in detail. There are other issues besides the long seam such as flaw detection. What you are saying seems obvious but some customers want proof from the code. I have located the Code Interpretation 8-36 where the code committee addressed exactly this issue and endorsed the...

I heard the code interpretation is 1990 vintage. Anyone have it? (rolled shells from plate) Rick

simply rolling a shell from plate. Rick

yes while this seems logical, I need something more concrete. I heard of a code intrepretation on the matter, do you know of it? Rick

does B31.3 allow the designer to use A 516-70 as a rolled plate shell without complying to ASTM A 672? the stress tables show pipe A 516-70 Spec A672 and then another listing for plate A 516-70. is the plate reference used only as flat plate?

I would generally like to hear about where 5Cr alloys are being applied. Also what differentiates the use of 3,5,9 Cr., other than allowable stress at design temp. Thanks, Rick

1) Does ASME Section VIII Div 1 have requirements depending on the type of process fluid or gas? 2) Specifically, does a fitting designed for HF acid require PWHT? Thanks, Rick

Aggman: Are you interpreting D3 to apply to the design of the pin connected member with a hole, but not actually to the bearing stress of the hole......and J8 applies to the design of the pin and hole? This is the same opinion as the consultant. If that's true D3 really throws me off because...

I am having a difference in interpretation with a consultant. Please let me know what you think. This is my side: AISC Manual of steel construction, 9th Edition. Section D3: 0.45Fy applies in determining the hole diameter and plate thickness related to bearing load at the pin hole & (J8) 0.90...

Is it generally true that maintenance of refinery piping falls under API and new construction falls under ASME? If so, where is that referenced in API code? Rick

Would API 2201 be relevant for refinery pipe hot tapping, or would it fall under ASME B31? Why? Thanks, Rick

I am trying to analyze shearing stress of (2) parallel plates and need confirmation in applying theory. Visualize the joint as (2) parallel plates projecting out of a base plate, there is a cross pin (located opposite end to the base plate) through the parallel plates of which a torsional load...

Thanks everyone for the input, I am following up on many of your comments. I am interested in further feedback on JL Analyser and Strand 7. Thanks, Rick

I am looking for a basic FEA program to use with AutoCAD 2d drawings. Typical use would be pressurized fittings and basic machine components. Does anyone have any suggestions that I should look at? How about AutoFEA JLAnalyzer 9.0? Thanks, Rick
