Design requirements for API standard 650 carbon steel tank

For the team, cooperation is the core idea of daily work, and the core of common cooperation is resource sharing. With a perfect resource sharing mechanism, the whole team can be called a unity spirit.A good team lies in the ability to transfer resources, knowledge and information in time among team members in order to achieve the common goals of the team. So that we can share experiences and lessons."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 carbon steel tank roof and sidewall.The liquid level of API 650 oil storage tank is covered by floating roof. The storage liquid of API 650 oil storage API standard 650 carbon steel tank tank is isolated from the air, reducing air pollution, fire and explosion hazards, and easy to ensure the quality of liquid storage. It is especially suitable for the API standard 650 carbon steel tank storage of high-grade gasoline, jet fuel and toxic and easily polluted liquid chemicals.In order to better develop the international steel market and make the steel products trade more prosperous at home and abroad, the company has a number of professional talents who love their posts and are proficient in their business. The company has always been adhering to the "service first, reputation first, customer first, make friends" business purpose, is willing to work together with domestic and foreign customers!Tank cracks are common API standard 650 carbon steel tank defects, mainly including tank wall cracks, internal cracks, weld zone cracks. The reason for these defects may be that the defects not exceeding the standard existed in the early stage of API standard 650 carbon steel tank construction, which become obvious after the later use. Or in the process of using the API standard 650 carbon steel tank, the tank body material generated new defects due to corrosion, pressure, wear and other reasons, and tank cracks.
