API standard 650 self-anchored storage tanks with self-supported roofs

The outer layer of API 650 tank is glass fiber reinforced plastic layer with a thickness of more than 2.5mm, which API standard 650 self-anchored storage tanks has strong corrosion resistance and electric corrosion resistance. Special process technology is used between the two layers to make the gap reach 0.1 mm, so as to eliminate the existence of potential safety hazard from the root.

When encountering heavy rain or continuous heavy rainfall, the safe operation of API standard 650 self-anchored storage tanks will be affected. For example: the API standard 650 self-anchored storage tanks is submerged, the oil unloading valve and the flame arrester valve are broken by water and the oil tank leaks. The oil tank area must do emergency work to prevent rainstorm to ensure the safety of the oil tank. Here are some safety protection measures for API standard 650 self-anchored storage tanks in heavy rain.

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 self-anchored storage tanks roof and sidewall.

Our company's business departments are a group of excellent and hard-working employees, who constantly carry out knowledge updating and steel knowledge training every day, only to provide better and professional services to customers.

The mode of iron and API standard 650 self-anchored storage tanks steel logistics transportation is mainly intercontinental ocean shipping and inland rail transportation. European ports have been very mature after years of development, such as Hamburg in Germany, Rotterdam in the Netherlands and Antwerp in Belgium. Relying on the huge market of the European Union, these ports are positioned in the logistics distribution function of cargo distribution and large import and export, and play a great role in the transportation of API standard 650 self-anchored storage tanks steel logistics.
