The legs are pipe and run 12+ " up the side of the vertical tank. The angle runs horizontally around the shell to bottom cone juncture. clp

deanc thank you - that helped. clp

I have a small 12" OD vertical ASME vessel (100spi/fv, 100F, 316L mat'l)and I'm having problems calculating the bottom "eccentric" cone. Typically cones are concentric and I'm not sure how to account for the eccentricity (or if it even needs to be considered in such a small vessel). Any...

Having trouble designing the bottom thickness for an ASME, ground supported flat bottom tank/.1 psi/ambient temp/120" dia/304SS material. Customer specifically wants ASME, not API tank. When I use the typical ASME equation for flat plates I get a thickness of 1.5". Is there a way to account for...

IRF, This is an atmospheric, API code, 14 ft dia tank and I'm concerned about fitting it within a specific code so that it can be stamped. I question the use of API-650 only because it is not a flat-bottom tank. I can not find a clear definition for API-650 tank bottoms. In Appendix J (J.3.2)...

Please help me with some clarification of the API-650 code for flat bottom tanks. It is my understanding that API-650 is for flat or flat sloped, ground supported bottoms only. So if I have a tank that has a 1:12 pitch, cone-shaped, ground supported bottom this would fall under API-620, not 650...

Does API-12F allow for a domed bottom. If yes, is it 6% knuckle radius?

Would someone please verify if the following is true (I believe it is but I am starting to doubt myself and need to hear it from someone else.) API-650 is for flat bottom tanks only - is this true? If an API tank has legs it would be an API-620 tank not 650 - true? one more question....can an...

API-620 code tank: We have a botton cone with 1/4" reinforcing angle and legs. The legs and angle interfere with each other. Will API-620 code allow the angle to be cut and welded to the legs or the legs to be notched out? I assume the answer is no but thought someone might know of a way around...

Looking for help on how to reinforce a knuckle on a F&D head:API-620 tank I have a 156" OD tank with a F&D bottom head and legs. The knuckle radius is 4" which is less that the 6% required per 5.12.3 of the API-620 code book.(6% of 156" is about 9.5") Is there any way to get around this 6%...

Is there a website out there that would tell me what seismic code is required per each state? For example WI uses IBC 2000, Iowa uses UBC 1997, Missouri uses IBC 2000, etc. Any recommendations on how to find applicable seimic codes per state would be greatly appreciated. Thank you.

When filling out an API-620 nameplate per 8.1.1 (fig 8-1); I am confused by what should be listed on the nameplate as an appendix. I assume that I am to list all the applicable appendixes used to design the tank...but that would be a long list and just doesn't seem correct for a nameplate. Am I...

Where would I look to find information on pressure ratings on threads (for threaded pipe and fittings)? I'm looking for the cut-off of when threads can be used and when the joints must be butt welded. I thought ASME B31.3 would have something but no luck. It would be greatly appreciated if...

For API-620 & 650 is the vapor space not less than 2% of total liquid no matter what the content?

API-620 requires a min of two 20" manholes - correct?

Steve, API-620 does not have rules for vacuum conditions....does that mean that it is not allowed or that with proper venting and good engineering practice you can design it for vacuum? Are the API codes typically pretty black & white or is there a lot of grey area?...I'm not sure where to draw...

Is there a minimum vacuum allowed with API-620?

Is there a minimum size manhole for API-650?

Steve, Basically I was wondering if there was a set min temp or if it was material dependant....you answered my question - thank you. clp

Is there a minimum temp restriction with API-650?
