API 650 carbon steel storage tanks size

The API 650 carbon steel storage tanks stiffener ring and backing strip (if used) are primary components, and they shall comply with the requirements of API 620 storage steel tank Q.2.1. The stiffener rings may be fabricated from plate using an intermittent weld on alternating sides between the web and the flange.
Except for aluminum or stainless steel tanks, all fillet welds shall consist of a minimum of two passes. The ends of the fillet welds shall be 2 in. from the rat hole (see Figure Q-1), and these welds shall be deposited by starting 2 in. from the rat hole and welding away from the rat hole. An acceptable alternative to the detail that includes stopping fillet welds 2 in. short of the rat hole would be to weld continuously through the rat hole from one side of the stiffener to the opposite side. All craters in fillet welds shall be repaired by back welding.

API 650 vertical tanks meet American Petroleum Industries (API) standards in design, material, fabrication, and testing of aboveground welded steel API 650 carbon steel storage tanksstorage tanks for use in industrial applications.

Myanmar 4800 tons ABS AH36 and ABS A shipbuilding plates. This is very good customer of us, and we have cooperated many times for shipbuilding plates API 650 carbon steel storage tanks . The most frequently ordered is shipbuilding plates, almost hundreds tons every 2 month, which are finally supplied to Myanmar’s navy. Just in last year, we have supplier more than 4800 tons shipbuilding plates for the customer continuously.

Inspection of API 650 carbon steel storage tanks bottom: magnetic flux leakage scanning technology is used to detect the corrosion condition of API 650 carbon steel 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 carbon steel 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 carbon steel 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.
