    EN Standards

    Good Afternoon Materials Engineer: Can you help me identify plate material meeting EN 10028-2 P265GH? Can you tell me what the ASTM equivalent is? Can you refer me to a producing mill? Thank you for your help. Regards, Thanks for your help, Kent.

    Design thickness as minimum plate thickness

    Good Morning jlcochran1: Thanks for the help. Please clarify the definition of "minimum permitted thickness". Is the minimum permitted thickness a minimum thicknes specified by the purchaser or how is it determined? Thanks for your help, Kent.

    Design thickness as minimum plate thickness

    Good Morning All: The tank is Type 316L stainless steel. In the API 650 calculations the design thickness is a decimal. Corrosion allowance is not a factor. I intend to order the plate from the plate mill based on the design decimal thickness. Do I have to add the allowable mill rolling...

    Layout Transition

    Where can I find a simple spreadsheet or other software solution to calculate the surface area and flat pattern for a square to round transition? Something simple, not costing a lot of money (mostly free), to be used for estimating the weight of the plate and the blank size of the plate used to...

    Large Flanges L.F. and L.M.

    I am looking at a BM that calls out a 92" LF special flange and a 72" Class 350 L.M. special. What does the L.F AND THE L.M. stand for? Thanks for your help, Kent.

    Shell Manway Cover Thickness API 650

    Is there a formula for calculating the thickness of a shell manway cover plate based on the tank height. The table in API 650 is handy but I would like to use a formula in my spreadsheet to calculate the thickness given the tank height, corrosion allowance and so on. Thanks in advance, Kent...

    516-70 vs 516-70N

    Who among you can give me a short course on the differences between SA516-70 as rolled and SA516-70 normalized? Under what applications does one callout have advantages over the other? Thanks for your help, Kent.

    Weld Shrinkage

    Good Morning: Thanks to all of you who took the time to reply. You may find it interesting to note that I posted the same question on the ASME Pressure Vessel and Piping Forum. My post logged 11 reads and 0 replies. It was startling to note that the first 40 posts in that Forum including mine...

    Weld Shrinkage

    Good Afternoon DeanC: Thanks for taking the time to respond to my question. However UG-96 refers me back to UG-80 and Part UHA discusses the selection of materials for vessel design. Neither gets into circumferential tolerences. But thanks anyway. Thanks for your help, Kent.

    Weld Shrinkage

    Good Morning BMoorthy. Thank you for responding to my inquiry. The head in question is: ASME 2:1 SE, 11.58 meters inside diameter, 28.58 mm minimum thickness, 50.8 mm straight flange, Construction: 3.66 meter crown plate with 13 equal petal segments. The joint design is double bevel 60% outside...

    Weld Shrinkage

    Who among you can comment on the amount of weld shrinkage to be encountered in welding large diameter segmented T316L SE pressure vessel heads? The heads are 38'Ø with a minimum thicknes of 1.125" and are fabricated from 13 segments. Do you know of any articles or studies addressing this...

    Dimensional Tolerances

    Where can I find a definitive interpretation and examples of the allowable tolerances for the diameter of a large vessel when strapping the circumference? The minimum and maximum allowable are stated in UG-80 but I couldn't spot a discussion pertaining top the circumference as it relates to the...
