API 650 anchored liquid-storage tanks ladders

The construction period comparison of mechanical cleaning and manual cleaning for vertical storage tank, API 650 anchored liquid-storage tanks. The API 650 anchored liquid-storage tanks mechanical cleaning period is short, and the construction period is not affected by the size of the storage tank and the amount of sludge in the tank, and the cleaning equipment operates 24 hours a day. The manual cleaning of the API 650 anchored liquid-storage tanks has a long construction period, which is easily affected by the external environment, and the number of workers is limited by the size of the storage tank and the amount of sludge.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 anchored liquid-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.The welded steel API 650 storage tank API 650 anchored liquid-storage tanks is designed, manufactured and installed on the surface according to the API standard system classification. API 650, API620 and API 12D belong to the API standards for professional construction.Our company was founded in 2009, and has been committed to steel business since its establishment.
