ASTM A662 plates API standard 650 aboveground petroleum storage tanks
API 650 petroleum storage tank stipulates that if the thickness of the lower siding obtained by calculating the anti-overturning moment is greater than the thickness of the API standard 650 aboveground petroleum storage tanks hydrostatic pressure test (both do not include the corrosion margin), the calculated thickness of the above siding required by the hydrostatic pressure is It should also be increased by the same proportion, unless special analysis is performed to determine the seismic overturning moment and corresponding stress at the bottom of each layer of API 650 petroleum storage tank wall.
No matter what type of storage tank needs to be built, the natural conditions of the geographical area where the tank is located should be fully considered in the design. Because natural conditions will affect the service life, storage safety and construction cost of storage tanks such as API standard 650 aboveground petroleum storage tanks. Generally, the natural conditions that need to be considered before API standard 650 aboveground petroleum storage tanks design and construction are: regional temperature, wind load, snow load, ground endurance, external environment corrosion, etc.
In this project, a cylindrical tank 62 ft 6 in. in diameter is designed for an internal pressure of 4 lbf/in.2 gauge in the vapor space. The plate material is ASTM A131 steel with appropriate grades for different plate thicknesses in accordance with Table 4-1 for a design metal temperature less than 65°F but not less than 25°F. No corrosion allowance is required for any portion of the tank. The top course of the butt-welded cylindrical sidewall is 1/4 in. thick. The roof is a single lap-welded spherical dome with an internal radius of 50 ft and a thickness of 1/4 in. The maximum design liquid level is 6 in. below the plane of the juncture of the tank API standard 650 aboveground petroleum storage tanks roof and sidewall.
The company regularly holds sales elites to share experiences, to promote the rapid growth of colleagues, and achieve the company and employees. The company conducts employee skill training and related knowledge video learning from time to time. All these things is to improve the employees' skills and literacy, and reflects its own value. It has always been the pursuit of BBN steel to enhance the employee’s ability and keep up with the times.
As steel transportation belongs to the transportation of major parts, so in the process of transportation, modern logistics technology, such as centralized transportation, information technology, is a bit out of place. Based on the current situation of China's API standard 650 aboveground petroleum storage tanks steel transportation industry, highway transportation is a way of transportation that many enterprises often choose. Naturally, its business volume also accounts for more than 50% of the whole API standard 650 aboveground petroleum storage tanks steel transportation industry.
