Design of under-bottom connections for API 650 self-anchored storage tanks

API was established in 1919. It is the first national-level business association in the United States. It is one of the earliest and most successful chambers of commerce in the world to formulate standards. An important task of API API 650 self-anchored storage tanks is to be responsible for API 650 oil storage tanks and natural gas. Standardization of industrial equipment to ensure the safety, reliability and interchangeability of equipment used in the industry.

Allowable Design Stresses
The maximum allowable design stresses for the API 650 self-anchored storage tanks materials outlined in Q.2.1 shall be in accordance with Table Q-3.The values for the allowable design tensile stress given in Table Q-3 for materials other than bolting steel are the lesser of (a) 331/3% of the specified minimum ultimate tensile strength for the material or (b) 662/3% of the specified minimum yield strength, but they are 75% of the specified minimum yield strength for the stainless steel, nickel alloy, and aluminum materials. Allowable test stresses are based on the limitation of API 620 oil tank storage standard Q.8.1.3.

When encountering heavy rain or continuous heavy rainfall, the safe operation of API 650 self-anchored storage tanks will be affected. For example: the API 650 self-anchored storage tanks is submerged, the oil unloading valve and the flame arrester valve are broken by water and the oil tank leaks. The oil tank area must do emergency work to prevent rainstorm to ensure the safety of the oil tank. Here are some safety protection measures for API 650 self-anchored storage tanks in heavy rain.
