You are correct that $24 will keep wine good in a small tank. Now multiply this small tank by 200 storage tanks that Gallo, Paso Robles, etc might have at one facility and may be filled/emptied a few dozen times per year depending on the wine type. Your $24 investment in now $60k. It's much...
This style of head is very common in the wine industry for field fabricated tanks. Normal shop fabricated tanks have truncated heads. The wine industry fills to the top to eliminate any air in the tank. The more wine is exposed to the air increases the chance for contamination. As far as...
I work for Mueller Field Operations and we normally fabricate tanks utilizing jacks. We have fabricated up to 1 million gallon tank. Normal application is to stop around a 40 ft diameter tank but we have gone up to 60 feet in the past. At stated by others, this method is preferred by use...
I spoke with a gentlemen on the API commitee and the section in question is S.4.11.3. This section was added on addendum 1 but left out of the latest addendum. This section lets users weld SS plates together in the shop and elliminate the offset requirement for the shop joints up to 1/2" thick.
Section 5.1.5.2 states an offset of 5t is required between adjacent shell courses. Does API allow this 5t offset requirement to be eliminated if the shell courses are shop welded.
We fabicate many SS vessels. We will purchase 48" wide sheets and shop weld the sheets together to create a 96"...
I am looking at a tank farm for a biodiesel facility and have a question about the impounding dike. 4.3.2.3.2(F) states a subdivision shall be provided for each tank greater than 100,000 or for a group of tank less than 150,000 gallons.
What exactly is the definition of a "subdivision". Is it...
That is basically what we have told them. They have this trough design in other tanks (non-stamped wine tanks). But this tank must be stamped because it has flammable luquid.
You are correct about the gasket actually sealing on the manway collar. And this isn't a oil tank, the customer will store brandy in this tank. And since brandy is a flammable liquid, they want a API stamped tank.
Customer would like to use a swing-in style manway and believes that 1.2.b justifies this manway because it is proprietary. This style of manway has a gasket on the inside of the tank, so the sealing point is actually at the shell wall.
I believe 1.2 is for piping only and does not include...

I have a customer that is wanting a cone bottom tank (sloping to center) built. Starting at the center of the tank will be a trough that will run all the way to the edge of the tank to an outlet.
The customer is using 5.8.2 as the justification for being able to use a trough in the...
Has anyone installed any other types of flush outlet nozzles besides the style detailed in section 3.7.8. Paragraph 3.7.8.6 indicates that other options are allowed but I have not been able to find any other styles. The "standard" outlet looks to be very detailed and expensive.
