3003 aluminum forgings API Std 650 self-anchored flat-bottom steel tanks

When as-rolled plate material complies with impact test requirements as specified here, the material need not be normalized. If, as with ASTM A516, the specification prohibits impact test without normalizing but otherwise permits as-rolled plates, the API 620 welded storage tanks material may be ordered in accordance with the above provision and identified as “MOD” for this API modification.

The application of API 650 is as stated by the American Petroleum Institute: The production and installation of our ground welded steel API Std 650 self-anchored flat-bottom steel tanks storage tanks are generally used in industry; under normal circumstances, the storage tanks installed on the industrial site in the United States are in accordance with API 650, API 620 and API 12d Standards are established.

Tunisia cutomer purchased around 1500 tons 304L,310S stainless steel plate from us and make tanks in August, 2017. The company was skilled in the design and manufacture of stainless steel tanks, API Std 650 self-anchored flat-bottom steel tanks processing systems and equipment for the food, dairy, beverage, chemical, pharmaceutical, biotechnology, and pure water industries. They also sent the inspection team come our company and visited our production line. After using our stainless steel plate, the customer was very satisfied with our products.

The foundation design of the API Std 650 self-anchored flat-bottom steel tanks should meet the requirements of foundation stability and deformation, that is, the API Std 650 self-anchored flat-bottom steel tanks foundation should not be crushed and the uneven settlement value of the foundation should be within the allowable range. The uneven settlement of the storage tank foundation should be specified in the design process of the safe allowable range, because excessive uneven settlement will reduce the safety of the API Std 650 self-anchored flat-bottom steel tanks and cause distortion and deformation of the tank wall and bottom plate.

First of all, we should establish a correct concept of after-sales service. Service concept is an important part of corporate culture and a long-term enterprise value concept. Our company's after-sales service embodies the concept of "customer first, sincere service for customers". As long as we are in the "sincere service for users" under the guidance of the idea, I believe we will get rich returns.
