EN 10025 S355 plates API standard 650 petroleum storage tanks
Corrosion of the API standard 650 petroleum storage tanks body caused by external conditions such as high temperature, rain, humidity, or inadequate anti-corrosion measures of the oil storage tank itself, the water-bearing deposits in the oil storage tank caused corrosion and perforation of the inner surface of the oil storage tank bottom plate. Defects fatigue cracks caused by stress, with the accumulation of time, the compressive strength of the API standard 650 petroleum storage tanks body decreases and corrosion cracks occur.
Inspection of Butt-welds in PipingButt-welds in piping and in API standard 650 petroleum storage tanks pipe fittings within the limitations of 1.3.2 (including the annular space of double- wall tanks) shall be inspected in conformance with API 620 oil tank standard Q.7.7.2 through Q.7.7.6. Longitudinal welded joints in piping that contains liquid shall be completely radiographed except for manufactured pipe welded without filler metal, 12 in. or less in diameter, which is tested hydrostatically or by eddy current to ASTM requirements.
Selection of nominal diameter D of API 650 storage tank. In the design calculation of API 650 storage tank, the bottom plate thickness is the net plate thickness, that is, the actual thickness minus the corrosion allowance. In the design and calculation of API standard 650 petroleum storage tanks wall thickness in hydrostatic test, the thickness of bottom plate is the total thickness of steel plate.
