Steel plate for shells of API 650 stainless steel storage tanks

API 620 Crude Oil Tank Pneumatic Pressure
An air pressure equal to 1.25 times the pressure for which the vapor space is designed shall be applied to the enclosed space above the water level. In the case of a double-wall tank with an open-top inner tank, where the air pressure acts against the outer tank and the inner tank is thus not stressed by the air pressure, the inner API 650 stainless steel storage tanks may be emptied of water before the pneumatic pressure test begins. The test pressure shall be held for 1 hour.

API 650 internal floating roof oil tank is a volatile liquid storage tank with a combination of a dome tank and an internal floating roof structure, which is a floating roof assembled under the dome of the API 650 stainless steel storage tanks storage tank. The combination of the vault roof outside the API 650 storage tank and the floating roof inside the tank has been widely used in gasoline, aviation kerosene and more volatile chemical liquids.

With the fast development in Myanmar, Myanmar navy build frigate every year. We Cooperate with Myanmar Navy from 2015. They purchased 412 ton LR AH36 steel plate from us as trial order in 2015. After receiving the API 650 stainless steel storage tanks goods, they speak highly of the quality and our service. After that they purchase the shipbuilding steel plate from us regularly. In May,2018, the Myanmar navy’s local representative visit our office and production line, and sign another contract 2025 ton steel order in our office.

The cost of mechanical cleaning for vertical storage tank, API 650 stainless steel storage tanks is low, almost all oil can be recovered, and the quality of recovered oil is high. The cost of manual cleaning for vertical storage tank, API 650 stainless steel storage tanks is high, the oil can not be recovered completely, and the quality of recovered oil is low. The mechanical cleaning of API 650 stainless steel storage tanks adopts fully enclosed operation, and separates oil, water and oil sand. There is no direct discharge of oily sewage and waste gas, which will not pollute the environment.
