CSA G40.21 Gr 50W plates API Std 650 anchored tanks
API 650 petroleum storage tanks use lightning protection, anti-static, and fire protection measures. The internal corrosion protection should be determined according to the API Std 650 anchored tanks storage medium, and the outer wall corrosion protection should be determined according to the soil quality of the buried tank.
Comparison of the quality of mechanical cleaning and manual cleaning of vertical storage tanks, API Std 650 anchored tanks. The mechanical cleaning of the API Std 650 anchored tanks 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 Std 650 anchored tanks 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.
