3003 aluminum forgings API Std 650 ground-supported liquid storage tanks

Uplift on Foundation
For API Standard 620 tanks with an internal design pressure less than 1 lbf/in.2 gauge, the uplift shall be taken as the smaller of the maximum uplift values computed under the following conditions:
a)The internal design pressure times 1.5 plus the design wind load on the shell and roof.
b)The internal design pressure plus 0.25 lbf/in.2 gauge plus the design wind load on the shell and roof.

The characteristics of the API Std 650 ground-supported liquid storage tanks internal floating roof structure of API 650 petroleum storage tanks: the inner floating roof or inner floating plate refers to the floating roof that floats on the liquid surface of the oil tank with the oil and liquid up and down. The API Std 650 ground-supported liquid storage tanks inner floating roof is used to cover the liquid. The surface is currently recognized as the most ideal and most economical and practical way to reduce oil evaporation loss.

In 2015, we offered 230 tons 309S and 310S stainless steel API Std 650 ground-supported liquid storage tanks plate to Vietnam fabrication company. The products are used in fabricating machine for this company. Then the customer sell the machine to south America and European market. This Vietnam company purchase more than 100 ton stainless steel from us every month.

Natural ventilation loss: the main cause of natural ventilation loss is that the API Std 650 ground-supported liquid storage tanks is not tightly sealed. This is usually due to corrosion perforation on the top of the oil tank, or there is a height difference between the two orifices. The air tightness of the mixture in the API Std 650 ground-supported liquid storage tanks is higher than that of the air, which causes the mixture gas in the tank to be discharged into the atmosphere from the lower hole, and the external air flows into the tank from the high hole, resulting in natural ventilation loss.

If customers have any difficult problems during use of the steel materials, they can contact the company's after-sales service department to feedback the existing problems. The after-sales department will reply as soon as possible to ensure that each customer has a good after-sales experience. Under special circumstances, the after-sales service department will start the problem-solving process, and the engineers in charge of the area will quickly follow up to solve the problem.
