API standard 650 aboveground petroleum storage tanks greater than 200 ft in diameter

Design of Compression-ring Regions
In this project, a cylindrical tank 30 ft in diameter is designed for an internal pressure of 5 lbf/in.2 gauge in the vapor space. The plate material is ASTM A131 Grade A steel for thicknesses of 1/2 in. and less. The top course of the butt- welded cylindrical sidewall is 1/4 in. thick, including a 1/16 in. corrosion allowance. The tank API standard 650 aboveground petroleum storage tanks roof is a butt-welded spherical dome with an internal radius of 30 ft and a thickness of 1/4 in., including a 1/16 in. corrosion allowance. The maximum design liquid level is 6 in. below the plane of the juncture of the roof and sidewall.API 650 petroleum storage tank has the advantage of long economic life: because there is no gas space on the liquid surface in the internal floating roof API standard 650 aboveground petroleum storage tanks storage tank, the vibration generated during the transportation of liquid inside and outside the tank is reduced.In October, 2018, our Malaysia customer purchased 600 Tons CCS-AH36 Ship Building Steel Plates to use in their shipbuilding project .This customer is a famous shipyard in Malaysia. Their company has the business scope of tourism, API standard 650 aboveground petroleum storage tanks shipbuilding, transportation and so on. As a terminal manufacturer, they have strict requirements on quality . After visiting our factory, the customer are very satisfied with the quality of this batch of API standard 650 aboveground petroleum storage tanks CCS-AH36 Ship Building Steel Plates.Weld inspection of API standard 650 aboveground petroleum storage tanks, vertical oil tank wall plate: In the welding inspection process of oil tank wall plate, attention should be paid to the defects of thick wall plate, such as incomplete penetration, incomplete root fusion and cracks. If there is a root incomplete penetration defect, it is necessary to open the weld joint with carbon arc air gouging and grinding machine grinding, or even weld through, and then weld again after the defect is removed.The 365 day service system is implemented, and the business, loading and delivery are handled as usual in holidays and festivals. Actively help users solve difficulties. When users encounter difficulties in handling business, they should actively coordinate with the external solution; if they need to solve the problems internally, they should solve them in a timely manner without prevarication and wrangling. In line with the API standard 650 aboveground petroleum storage tanks principle of "fairness, justice and timeliness", coordinate with relevant departments and deal with all kinds of objections in a timely manner.
