API Spec 5L pipe API standard 650 ground supported tanks

Ultrasonic testing can find the internal defects of API standard 650 ground supported tanks welding joint, this detection method is very accurate for the internal layer defects of oil tank, but ultrasonic detection is not suitable for the detection of thin-walled storage tank materials. Dye penetrant testing is only suitable for detecting the defects of the surface opening of API standard 650 ground supported tanks and so on metal oil tanks. The feature of this method is convenient and fast.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 ground supported 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.Welded steel API standard 650 ground supported tanks storage tanks that are designed, manufactured and installed on the ground are classified according to the API standard system. The three API standards API standard 650 ground supported tanks all adopt on-site production and installation of storage tanks.Product concept: take the technology leading as the pillar of the enterprise, achieve the development goal of the enterprise with the reliable products, the reliable technology and the trustworthy services, and devote to the creative reform activities leading in the technical development and career of the industry to create new value through continuous change.We are known as API standard 650 ground supported tanks leading manufacturers, suppliers and exporters in the market all over the world.
