API Std 650 welded steel oil storage tanks fabrication
Normal pressure API 650 storage tank: When the gas side pressure of API 650 storage tank is the same as atmospheric pressure or less than 13 atmospheres (gauge), API Std 650 welded steel oil storage tanks is called atmospheric storage tank. API 650 petroleum storage tanks low pressure storage tank: when the pressure is greater than 13 atmospheres (gauge) and less than 0.1MPa, it is called low pressure storage tank.
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 steel oil 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.
The cleanliness of the API Std 650 welded steel oil storage tanks has a great influence on the safety of the tank and the quality of the oil stored. Keeping the API Std 650 welded steel oil storage 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 welded steel oil storage 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.
The 2019 Year of the Pig is the 70th anniversary of the founding of the People's Republic of China. Growing up with the motherland, our company sang songs to the mark the 70th victory anniversary. In September, we organized all employees to sing "My Country and I" and made a film.
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 welded steel oil storage 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 welded steel oil storage 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.
