One more thing, wich part of ASME code states that I should use full vacum design??. the vessel has an operation pressure range of -0.2/1.0 BAR(g). In this case should I use 14.7 psi of external pressure??? Thanks

Thank You!!!

Hi.. Im currently using pv elite as the software aproved by the client, but im getting an error, induced by external pressure. I would like to know if it is mandatory to run an external pressure design on the vessel, using 14.7 psi as the external pressure, the issue its that im obtaning a shell...

I am working on the design of a vessel that has torispherical heads and im having a litlle trouble about it. With a design load of 15 psi the calculated head thickness is around 5/16". This was calculated using the general vessel formulas from table 2-1 of the Pressure Vessel Design Manual by...

Hi, in the design of pressure vessels, the data sheet of the pressure vessel says "Design Pressure of A36 at design temp.". the question its where I can find that value?,in wich table of wich rule or Code.

In the designing of Water Storage tank, is there a rule or method of determining if its necessary, to use columns and rafters?. I have a Tank with 16 feet x 23 feet and a conical "self supported" roof of 3/16" thick, and a Tan 20º of slope. Thanks.

ok thanks for your advice, and by the way, its 16 FEET x 22 FEET, sorry about that.

yes its a small tank, about 16" of diameter and 22" of height, the material to be used its A-36 carbon steel. Its a ground supported water storage tank.

Hi, im designing an paraffin storage tank, but in order to make the contents allowable to be pumped, a steam coil system will be used. HOW DO I DESIGN A STEAM COIL SYSTEM, its there any information available to do this, any rules or something??. the steam passing thru the coil its saturated at...

Hi, im designing a water storage tank, can i use the API-650 to do all the calculations??

Hi. Im designing an API-650 storage tank, the calcs say that the tank must be anchored, the problem it that I dont know how to calculate the lenght of the anchor bolts, in order to design the foundation. any guidelines??, rules or something??. help please. Alex

Sorry I Mean anchor bolt chairs on a vertical tank. Thanks.

hi, is there a recomended method or specification by any rule, to design the saddles in anchored aboveground tanks?? Thanks

hi, is there a recomended method or specification by any rule, to design the saddles in anchored aboveground tanks?? Thanks.

Hi, some of the beams we adquired for the construction of a skid, came withs "details" so its there a rule or a specification, that describe the allowable defects on beams?. One of the beams came with a scratch of 0.6 mms deep, on the web section. the question its if we can use that beam or just...

it helped a lot. thanks, and by the way, I got the addendum 4, and it changed everithing. thanks again.

Hi, we are designing a Storage Tank under API STD 650, but we dont have very clear how to calculate the wind moment as its described in 3.11. Anything would be apreciated. Thanks
