API 620 vertical steel storage tank roof and top-angle joints
The API 620 vertical steel storage tank outer wall shall be designed for the purging and operating pressure of the space between the inner and outer tank shells and for the loading from the insulation, the pressure of wind forces, and the roof loading.The outer tank bottom, shell, and roof shall have a minimum nominal thickness of 3/16 in. (7.65 lbf/ft2) and shall conform to the material requirements of Q.2.3.
API 650 petroleum storage tanks are used for API 620 vertical steel storage tank storage. API 650 petroleum storage tanks can be made of carbon steel, austenitic stainless steel and nickel alloy (only for low temperature). Welding API 620 vertical steel storage tank certification is regulated by Section 10 of the American Society of Mechanical Engineers (ASME). For API 650 petroleum storage tanks, non-destructive inspections are required, but third-party inspections are not required.
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.
To scientifically evaluate the remaining service life of the API 620 vertical steel storage tank, it is necessary to know the thickness change and development trend of the storage tank sheet after long-term use, combined with the metal characteristics of the storage tank, the influence of various external conditions and the continuous change of the oil pressure in the API 620 vertical steel storage tank, etc. factors to judge. Because the metal characteristics, corrosion defects, load and other numerical parameters of the API 620 vertical steel storage tank are randomly changed, the value of the remaining service life of the storage tank will also be dynamic.
