API standard 650 self-anchored tanks load combinations

To scientifically evaluate the remaining service life of the API standard 650 self-anchored tanks, 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 standard 650 self-anchored tanks, etc. factors to judge. Because the metal characteristics, corrosion defects, load and other numerical parameters of the API standard 650 self-anchored tanks are randomly changed, the value of the remaining service life of the storage tank will also be dynamic.Standard Hydrostatic and Pneumatic TestsAfter erection is completed and stress relieving, radiographic examinations, or other similar operations, as may be required, are performed, each tank shall satisfactorily pass a series of hydrostatic and pneumatic tests as prescribed in 7.18.2 through 7.18.6. Whenever a solution film is specified in this section to be applied to welding, linseed oil or another equivalent material for disclosing air leakage may be substituted. In freezing weather, linseed oil or a similarly suitable material shall be used.The attachment welding around all openings and their reinforcements in the walls of the API 620 tank shall be examined by the magnetic-particle method both inside and outside the tank API standard 650 self-anchored tanks. When the underside of a tank bottom rests directly on the tank grade (and is not accessible after erection), such examination of welding on the underside of the bottom and subsequent air testing may be omitted.The advantages of API 650 floating roof tanks have obvious environmental and economic benefits: in a specific climate environment, according to historical data, the economic value of the API standard 650 self-anchored tanks floating roof tanks in API 650 due to the reduction of oil and gas volatilization within 3-6 months is equivalent The installation and purchase cost of the API standard 650 self-anchored tanks inner floating roof means that the cost of the inner floating roof can be recovered within half a year.Corporate mission: to provide high quality steel products API standard 650 self-anchored tanks and services to global customers.Strategic goal: to be the leading steel materials supplier in the world.Enterprise core values: people-oriented, customer first, quality oriented, comprehensive and open, continuous innovation.Customer first is to always put the satisfaction of customer needs first.
