13.5m diameter API 650 vertical welded storage tanks

After using for a certain period of time, it is necessary to check the corrosion protection of the metal oil tank and paint the outer wall of the API 650 vertical welded storage tanks with anti-corrosion paint. The inlet and outlet valves of API 650 vertical welded storage tanks shall be inspected and maintained regularly to ensure they are in good condition. Oil tank will produce a lot of dirt when it is stored for a long time. Usually, the cleaning cycle of metal oil tank is about three to five years.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 650 vertical welded storage 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.Similarities between API 650 and API 620 tanks Both tanks are used for storage purposes. Both API 620 and API 650 containers API 650 vertical welded storage tanks can be made of carbon steel, austenitic stainless steel and nickel alloy (only for low temperature).Enterprise mission: to create value added steel products API 650 vertical welded storage tanks and provide first-class serviceWe are committed to quality.
