    Saddle Calculation for Launcher & Receiver

    I have horizontal launcher-receiver designed to B31.8, saddle mounted and bolted on skid. Not sure what calculation shall be provided by the trap manufaturer for the saddle. Can not find any reference to saddle calculation in B31.8. Is Zick Analysis (for pressure vessel) acceptable even though...

    Flange rating mismatch

    I have a situation where instrument nozzle on vessel is CS 600#. But specification dictates that level guage flanges should be 316 SS. I can not use 600# SS flange because of lower strength of SS. Is there any duel certified material (or other solution) that I can use instead of upgrading to...

    ASTM A694 Flange material

    Thank You Metengr. My application is pig launcher for gas line. Launcher material API 5L Gr 65. DP 1467 psi @ DT 150F. I want to check ASTM A694-F65 600# flange rating at 150 F. But can not find it anywhere. What is the procedure?

    ASTM A694 Flange material

    NozzleTwister, Thank you. But I think MSS-44 is for large flanges. Does it apply to small bore flanges (2" to 8") as well?
