A516 grade 485 plates API Std 650 mechanically-anchored steel tanks

Fixed roof API 650 oil storage tank includes inner floating roof tank, which API Std 650 mechanically-anchored steel tanks can effectively prevent sand, rain, snow or dust from polluting the storage liquid. Under various weather conditions, API 650 oil storage tank can ensure the quality of liquid storage, which is called "all-weather API Std 650 mechanically-anchored steel tanks storage tank".

The cleanliness of the API Std 650 mechanically-anchored steel tanks has a great influence on the safety of the tank and the quality of the oil stored. Keeping the API Std 650 mechanically-anchored steel tanks clean can slow down the corrosion of the tank wall and reduce the pollution to the oil. If the inside of the API Std 650 mechanically-anchored steel tanks is not cleaned all the year round, a lot of rust and metal impurities will be produced in the tank. These impurities will cause the oil to slowly oxidize and deteriorate. The impurities mixed into the oil will also block the filter and oil circuit, causing oil supply failure.

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 mechanically-anchored 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.

In line with the service concept of "honesty first, customer first" and the service tenet of "all for customer satisfaction", the company adopts the acceptance and response mode of combining manual and automatic, and accepts the diversified service demands of customer business consultation, complaint declaration, business acceptance, etc. through telephone, fax, e-mail, visit, letter, etc.

Japan is a typical shipping first, and its raw materials are imported from Oceania, central and South America and other Asian countries. Most of the API Std 650 mechanically-anchored steel tanks steel produced is exported to China and other Asian countries, and a small amount is exported to America. Shipping is the main way of its API Std 650 mechanically-anchored steel tanks steel international transportation. According to the data, steel goods account for about 20% of the total sea freight in Japan. The domestic transportation of Japanese steel is mainly truck.
