Gentlemen,
We are looking into building a vessel 28 feet in diameter x 308 feet tall out of SA-537 Gr.2 material 1 ¼” thick. The design temperature is -50°F so the material will require impact testing. Will heat treating be required by the ASME Code?
Thanks...
Hello All,
My company is currently fabricating three LNG Tanks, and the temperature can reach -265 Deg. F. I am in the process of trying to purchase some 4" and 6" 150# Flanges that would be good for this temperature. Some of the Flanges will need to be Stainless Steel, and some are...
Gentlemen,
Does anyone know if a 2006 Addenda has been issued for ASME BPVC Section VIII, Divsion I, 2004 Edition? And if so, where can I find a copy? Thanks... Also, if I have a shop that is getting a vessel U-Stamped to the 2006 Addenda, but the COMPRESS calcs do not have the 2006...
Gentlemen,
Does anyone know of or have a design standard they use when deciding whether to use a 2:1 Elliptical Head or an F&D Head in their design? I know 2:1 Elliptical Heads are usually used for small and medium diameters, and higher pressures. And F&D Heads are usually used for lower...

1. For one of my Nozzles located in...
Hello All,
During the forming process of ASME Heads, where does the most Thin-out occur? Or what area of the Head will see the highest stresses? Thanks....
Hello All,
Does anyone know if it is a good practice to include Nozzle Loadings for Flange Ratings? What I mean is, in COMPRESS there is a check you can perform that will include external nozzle loadings in the Flange Rating. Or it will also use the Nozzle Loadings to limit the MAWP...
Are X-Rays of the Welds required after PWHT? I thought that they are required because you need to check the integrity of the welds and the properties. One of our QC guys do not think this is the case. Thanks...
Does the ASME Code mention anything about what Material can and can not be used to make Tray Rings for Pressure Vessels. We use Rolled Flat Bar to make our Tray Rings. Someone has mentioned that they have to be made out of plate. Thanks...
Hello,
I have a Pressure Vessel that I am working on for another Customer, that has specified SA516-70N & it also needs to be PWHT. I would like to know if anybody knows wheather I can get rid of the Normalized requirement, if I PWHT to the Temperature required to Normalize the Material...
