API Std 650 aboveground oil storage tanks for liquids storage

The specifications used in the design of large oil tanks, API Std 650 aboveground oil storage tanks mainly include American Petroleum Institute Standard API 650, Japanese Industrial Standard JIS B8501, British Industrial Standard BS2654 and Chinese National Standard GB50341 from a global perspective. The formulas used in each specification are based on the hoop stress in the membrane theory. Each specification is based on the performance characteristics of materials and the construction technology level of their respective countries to determine the allowable stresses and weld coefficients. Therefore, the calculation results of tank wall thickness of API Std 650 aboveground oil storage tanks with the same volume are sometimes quite different according to different specifications.

Protection of Plates during Shipping and Storage
Plates shall be adequately protected during shipping and storage to avoid damage to API Std 650 aboveground oil storage tanks material plate surfaces and edges from handling (scratches, gouge marks, etc.) and from environmental conditions (corrosion, pitting, etc.).
Plates shall be protected from moisture or stored in inclined position to prevent water from collecting and standing on surface.

This API 650 tank standard is designed to provide industry with tanks of adequate safety and reasonable economy for use in the API Std 650 aboveground oil storage tanks storage of petroleum, petroleum products. and other liquid products.
