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 650 storage 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.The welded API 650 tank in various sizes and capacities for internal pressures approximating atmospheric pressure (internal pressures not exceeding the weight of the roof plates), but a higher internal pressure API 650 storage tanks is permitted when additional requirements are met.Firmly establish the "people-oriented, safe development" concept, strictly follow the safety production policy of "safety first, prevention first, comprehensive management", strengthen and improve the management and supervision of safety production in an all-round way, and strive to improve the controllability of safety management And effectiveness, cultivate safety culture, improve long-term safety production mechanism, and build a harmonious BEBON.Natural ventilation loss: the main cause of natural ventilation loss is that the API 650 storage tanks is not tightly sealed. This is usually due to corrosion perforation on the top of the oil tank, or there is a height difference between the two orifices. The air tightness of the mixture in the API 650 storage tanks is higher than that of the air, which causes the mixture gas in the tank to be discharged into the atmosphere from the lower hole, and the external air flows into the tank from the high hole, resulting in natural ventilation loss.
