5154 aluminum pipe API standard 650 unanchored flat-bottom tank
Similarities between API 650 and API 620 tanks Both tanks are used for storage purposes. Both API 620 and API 650 containers API standard 650 unanchored flat-bottom tank can be made of carbon steel, austenitic stainless steel and nickel alloy (only for low temperature).
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 unanchored flat-bottom tank 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.
Comparison of the quality of mechanical cleaning and manual cleaning of vertical storage tanks, API standard 650 unanchored flat-bottom tank. The mechanical cleaning of the API standard 650 unanchored flat-bottom tank can make the inside of the tank be thoroughly cleaned in multiple directions, and the cleaning quality is high, and the cleaned oil does not contain lumpy impurities. While the walls and roof of the API standard 650 unanchored flat-bottom tank cannot be cleaned in multiple directions during manual cleaning, and the cleaning quality is not easy to be guaranteed. The oily sewage collected after cleaning usually contains a lot of lumpy impurities, and these oil products are difficult to clean.
