In cases in which the rate of corrosion is closely predictable, additional metal thickness over and above that required for the initial operating conditions shall be provided and shall be at least equal to the expected corrosion loss during the desired life of the tank.
When corrosion effects are indeterminate before the tank is designed (although they are known to be inherent to some degree in the service for which the tank is to be used), and when corrosion is incidental, localized, or variable in rate and extent, the best judgement of the API standard 650 flat-bottom steel tanks designer must be exercised in establishing reasonable maximum excess tank wall thicknesses. For all tanks that come under this classification, a minimum corrosion allowance of 1/16 in. shall be provided.API 650 is an American standard for welding flat bottom vertical storage tanks. This API standard 650 flat-bottom steel tanks standard specifies requirements for the design, manufacturing, welding, inspection and installation of storage tanks. API 650 is widely used in storage tanks designed to withstand low internal pressures and used to store typical products such as API standard 650 flat-bottom steel tanks crude oil, gasoline, chemicals and water.
