ASTM A181 forgings API Std 650 welded storage tanks
Comparison of the quality of mechanical cleaning and manual cleaning of vertical storage tanks, API Std 650 welded storage tanks. The mechanical cleaning of the API Std 650 welded storage 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 welded storage 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.
For all API 620 crude oil tank other materials, the impact test temperature shall be at least 30°F colder than the design metal temperature. Alternately, materials impact tested at the design metal temperature or lower with Charpy impact test energy value of 25 ft-lb (average), 20 ft-lb (minimum) are acceptable for design metal temperatures above –40°F. API Std 650 welded storage tanks materials with an energy value of 30 ft-lb (average), 25 ft-lb (minimum) are acceptable for design metal temperatures of –40°F or lower.
Prevent the storage liquid from impacting the inner wall of the API 650 petroleum storage tank or increase the internal pressure, reduce the corrosion of the tank top and the tank wall, and extend the service life of the API Std 650 welded storage tanks storage tank.
