Large Low-Pressure Tanks Corrosion Allowance
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 620 crude oil storage tank 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 company has the industry's advanced automated production lines and precision laboratory instruments and a capable steel industry management team. Through scientific management, optimized technology, and rigorous testing, the company will keep the production efficiency and production quality at the leading level in the industry and continue to provide customers with high-quality API 620 crude oil storage tank products. At the same time, the company is committed to building a comprehensive steel manufacturing industry and strives to make the company leads new progress and development.

The company always insists on quality first. "Tolerance and trust, change and innovation, abide by rules, and focus on refining people" are the eternal credo of the team. Encouraged by the same creed and belief, BEBON people continue to grow and mature, and the team size is increasing expand. In the future, look beyond Chinese private steel companies to see BEBON. Looking to the future, we are not blindly pursuing bigger scale, but we are pursuing strength and brand strength.

The seismic effects on the tank wall of API 650 oil storage tank include the inertia moment generated by the weight of the API 620 crude oil storage tank tank and the hydrodynamic pressure of the reservoir, which can be divided into short period pulse pressure and long period fluid slopping convective pressure.
