API 650 aboveground oil storage tanks metal-seated ball valve
Inspection of API 650 aboveground oil storage tanks bottom: magnetic flux leakage scanning technology is used to detect the corrosion condition of API 650 aboveground oil storage tanks bottom plate (such as corrosion depth and area, crack length, etc.). When there is a defect in the bottom plate of the API 650 aboveground oil storage tanks, the magnetic field distribution will change and the sensor can detect it. The bottom of the oil tank should be free of foreign matters and dry during testing. Weld inspection of API 650 aboveground oil storage tanks bottom plate: when vacuum leak test method is used to detect the tightness of oil tank bottom plate, soap water shall be applied to the weld and vacuum box shall be covered for observation.
API 650 aboveground oil storage tanks basic components are those that contain the vaporized liquefied gas from the stored refrigerated liquid but primarily operate at atmospheric temperatures because of insulation system design and natural ambient heating. These components shall comply with the basic rules of this standard. Examples of such components are the outer wall and roofs of double-wall tanks and roof components above an internally insulated suspended deck. The API 620 tank materials requirements are based on the storage of refrigerated products at the design metal temperature.
API 650 is an American standard for welding flat bottom vertical storage tanks. This API 650 aboveground oil storage tanks standard specifies requirements for the design, manufacturing, welding, inspection and installation of storage tanks. API 650 is widely used in storage tanks designed to withstand low internal pressures and used to store typical products such as API 650 aboveground oil storage tanks crude oil, gasoline, chemicals and water. BBN has extensive experience in API 650 tanks, from +/- 500 cubic meters of tanks produced in the factory to +/- 15000 cubic meters of tanks produced on site.
