ASTM A671 pipe API standard 650 SUG II tanks
API 650 storage tank is used for commonly used oil, gasoline, diesel, chemical and production water storage. API standard 650 SUG II tanks Storage tanks built to these standards are spread across U.S. refineries, terminals, pipelines, and production facilities. The API 650 detailed standard specifies the design, processing, welding, inspection and installation procedures for storage tanks.
Generally speaking, the duration of the "exhalation" of the API standard 650 SUG II tanks is longer than that of the "inhalation" of the API standard 650 SUG II tanks every day. There are many factors affecting the "small breathing" loss, mainly including the following points: the change of temperature difference between day and night, sunshine time of the API standard 650 SUG II tanks location, open area of the API standard 650 SUG II tanks, atmospheric pressure, filling degree of API standard 650 SUG II tanks, etc. When the API standard 650 SUG II tanks is full of gas, the space volume is small, and the "small breathing" loss is less; if the space volume is large, the loss is also large.
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 SUG II 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.
It is very important for an enterprise to have a sound after-sales service system, which not only ensures the normal outflow and inflow of the company's products, but also improves the trust of the company's products in the hearts of customers. Our company has a special after-sales service team and good after-sales service reputation.
