API Std 650 self-anchored flat-bottom steel tanks impact tests

BBN excels in the design, fabrication and erection of API-650 tanks. API (American Petroleum Institute) has created a set of standards for above ground API Std 650 self-anchored flat-bottom steel tanks oil storage, but these tanks are also commonly used for gasoline, chemical and water storage. API-650 storage tank solutions range in size from an 8’ -0” diameter shop fabricated tank up to and beyond 100’ -0” diameter field erected storage tank applications.

Strictly controlling the temperature in the API Std 650 self-anchored flat-bottom steel tanks can effectively reduce the volatile consumption of oil in large oil storage tanks. Because the higher the temperature in the oil storage tank, the stronger the activity of oil molecules and the greater the volatilization consumption of the oil. Therefore, the temperature in the API Std 650 self-anchored flat-bottom steel tanks must be reduced as much as possible. It is possible to reduce the direct sunlight temperature by painting white anticorrosive paint with good light reflectivity. It is also possible to use spray equipment to wash the top and wall of the API Std 650 self-anchored flat-bottom steel tanks with water flow to reduce the volatilization consumption of the oil in the storage tank.

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 self-anchored flat-bottom steel 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.

Customer service center has provided after-sales service for many large-scale information systems, and has accumulated rich working experience in the process of API Std 650 self-anchored flat-bottom steel tanks service for many years. It can provide accurate, timely and high-quality support and service for users, which is well received by users.

BBN company has implemented a resource strategy combining global resource procurement, domestic resource unified purchase, and joint purchase and distribution. It has maintained good relations of cooperation with more than 100 domestic and foreign steel mills, and can purchase low-quality and high-quality steel futures in all directions and through multiple channels. The company can grasp the specifications and quantities of the spot resources of major steel mills in real time, and can timely and quickly meet customer demand for steel spot resources.
