    B31.3 Plate Shell

    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?

    5Cr Alloys

    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

    Pin Connected Member

    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...

    API 2201 Hot Tapping

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

    Shearing Stress of Parallel Plates

    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...

    FEA Program

    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

    R13 Upgrade

    I am considering upgrading R13 to 2004. I need tangible justification. Our business is oilfield manufacturing and field operations related. Will I recover the $5000 CAD per seat in 1 year? Through what efficiencies? Having the latest revision in itself is not meaningful to our business nor our...

    ASME PCC-1 BOLTED FLANGE ASSEMBLY PROCEDURE

    I recently obtained a copy of ASME PCC-1 2000 Edition, Guidelines for Pressure Boundary Bolted Flange Joint Assembly. Is this a proposal for future drafts of the B&PV code? What is the meaning of the designation ASME PCC-1? Rick

    API 6A App. D RTJ Torque Values

    How are API 6A App. D recommended torque values applied to an RTJ. Am I to perform a calculation similar to ASME Sec 8 Div 1 App2 to determine bolt stress? API 6A, APP D recommends 40 and 52.5 ksi bolt stress, but for what application? Rick

    ASME Appendix 2 flange stress calculations

    Are ASME Section VIII Div1 Appendix 2 flange stress calculations allowable limits and rational indicators of degrees of internal stress, or are the calculations true measures of physical internal flange stresses?
