API standard 650 duplex stainless steel tanks problem solution

Oil, Gas, Chemical, Water, and Bio-Fuel storage. Maximum of the most common welded steel tanks used in industry are designed following API 650. Tanks typically found in Refinery API standard 650 duplex stainless steel tanks tank farms, Terminals, Pipelines, and other process facilities use these tanks.

All API standard 650 duplex stainless steel tanks fillet welds shall consist of a minimum of two passes. The ends of the fillet welds shall be 2 in. from the rat hole, 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 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.

Inspection of API standard 650 duplex stainless steel tanks bottom: magnetic flux leakage scanning technology is used to detect the corrosion condition of API standard 650 duplex stainless steel tanks bottom plate (such as corrosion depth and area, crack length, etc.). When there is a defect in the bottom plate of the API standard 650 duplex stainless steel 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 standard 650 duplex stainless steel 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.
