API 650 duplex stainless steel tanks overturning stability

Volatilization is the characteristic of oil. Under normal temperature and pressure, as long as the oil is in contact with air, the surface will volatilize. Through scientific analysis and summary, the causes of oil volatilization loss in API 650 duplex stainless steel tanks are: natural ventilation loss, static storage loss, dynamic liquid level loss. In the use of API 650 duplex stainless steel tanks, static storage loss and dynamic liquid level loss are common losses.

A cylindrical nozzle with a 12-in. inside diameter is located in solid plate in the sidewall of a cylindrical storage tank 60 ft in diameter so that its axis lies in a horizontal plane and forms an angle of 55° with a perpendicular to the sidewall at the point of intersection, as shown in Figure F-7. The thickness of the API 650 duplex stainless steel tanks sidewall plate, tw, in this area is 5/8 in., and no corrosion allowance is required. The total internal pressure, Pl + Pg, at the center of the opening is 26.1 lbf/in.2 gauge.

The API 650 petroleum storage tank standard is one of the most widely used design specifications. It is the API 650 standard of the American Petroleum Institute. The main goal of the API 650 standard is to promote the purchase and construction of vertical, above-ground, and welded manufacturing API 650 duplex stainless steel tanks tanks through the requirements contained in its parts to ensure that the required safety regulations are met.

The cultural construction must let the enterprise staff participate in the enterprise culture, in order to better carry on the effective dissemination enterprise idea, the sharing value system, such as the internal communication, the newspaper, the forum, the propaganda, the news announcement and so on. At the same time, the system can also be used to educate and train employees, send blessings to employees on their birthdays or during Chinese New Year holidays, so that employees can feel the practice of corporate culture, the warmth of the enterprise, and enhance the sense of belonging and recognition of the enterprise.
