API Std 650 unanchored liquid-storage tanks alternate designs

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 Std 650 unanchored liquid-storage tanks storage tank, the vibration generated during the transportation of liquid inside and outside the tank is reduced.

The establishment of a correct method for evaluating the life of API Std 650 unanchored liquid-storage tanks requires the preparation of criteria related to the strength and cracks of API Std 650 unanchored liquid-storage tanks, mechanical damage mechanisms, corrosion mechanisms, and mathematical models of fatigue crack growth, etc., which are compiled into computer programs. In the process of programming the program, it is required to select the operating parameters, plates, reinforcement accessories, metal properties, corrosion levels, mechanical damage defects and other data of the oil storage tank under various conditions.

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 Std 650 unanchored liquid-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.

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 Std 650 unanchored liquid-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 Std 650 unanchored liquid-storage tanks steel transportation industry.
