API standard 650 carbon and low-alloy steel tanks intermediate wind girders

The cleanliness of the API standard 650 carbon and low-alloy steel tanks has a great influence on the safety of the tank and the quality of the oil stored. Keeping the API standard 650 carbon and low-alloy 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 standard 650 carbon and low-alloy 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.

In this project a cylindrical tank 75 ft in diameter is designed for an internal pressure of 0.5 lbf/in.2 gauge in the vapor space. The plate material is ASTM A131 Grade B steel for thicknesses of 1/2 in. and less.
The top course of the butt-welded cylindrical sidewall is 1/4 in. thick. The tank API standard 650 carbon and low-alloy steel tanks roof is a conical shape with a 2:12 slope and a 1/4 in. thickness with single full-fillet welded lap joints. The maximum design liquid level is 6 in. below the plane of juncture of the roof and sidewall.

We also specialize in internal and external floating roofs, cathodic protection, primary and secondary containment, and storage tank foundations. Our staff are skilled in producing API 650 petroleum storage tanks.
