Construction of under-bottom connections for API standard 650 cylindrical liquid-storage tank

API 650 petroleum storage tanks use lightning protection, anti-static, and fire protection measures. The internal corrosion protection should be determined according to the API standard 650 cylindrical liquid-storage tank storage medium, and the outer wall corrosion protection should be determined according to the soil quality of the buried tank.

In the process of API standard 650 cylindrical liquid-storage tank steel transportation, enterprises often use railway transportation, highway transportation, water transportation and other ways to transport. According to the cargo owner's requirements on the timeliness of the goods and the different transportation routes, our company will choose API standard 650 cylindrical liquid-storage tank different modes of transportation. According to the specific needs of customers, or specify the mode of transportation.

We have a professional after-sales service team, the company has developed a clear service process and service standards, after-sales service team members strictly perform after-sales procedures, comply with service standards. The most important thing is that we have set up the correct concept of after-sales service, "customer first, sincere service for users".

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 standard 650 cylindrical liquid-storage tank may be emptied of water before the pneumatic pressure test begins. The test pressure shall be held for 1 hour.
