API standard 650 storage tank qualification of welding procedures

The API standard 650 storage tank must go through strict inspection before putting into use. Inspection of plate groove of API standard 650 storage tank, vertical oil tank: After finishing the groove processing of oil tank plate, it is necessary to conduct dye penetrant inspection on the groove. This process is mainly aimed at the hard damage of groove in the machining process and the defects of the plate itself. If any defect is found, it shall be processed again until the defect disappears.A cylindrical nozzle with a 12-in. inside diameter is located in solid plate in the sidewall of a cylindrical storage tank 60 ft in diameter so that its axis lies in a horizontal plane and forms an angle of 55° with a perpendicular to the sidewall at the point of intersection, as shown in Figure F-7. The thickness of the API standard 650 storage tank sidewall plate, tw, in this area is 5/8 in., and no corrosion allowance is required. The total internal pressure, Pl + Pg, at the center of the opening is 26.1 lbf/in.2 gauge.Storage tanks API standard 650 storage tank built to these standards are spread across U.S. refineries, terminals, pipelines, and production facilities. The API 650 petroleum storage tank detailed standard specifies the design, processing, welding, inspection and installation procedures of the storage tank.With the development of China's market economy, the company vigorously implements the strategy of industrialization, internationalization and diversification, promotes the group operation, intensive development and lean management, and through a rich series of products and project portfolio as well as a complete operation network, Build the company into a modern enterprise with scientific development concept, continuous innovation vitality, excellent corporate culture, strong sense of social responsibility and international first-class competitiveness.We are known as API standard 650 storage tank leading manufacturers, suppliers and exporters in the market all over the world.
