ISO 630 grade E355 plates API Std 650 horizontal tank
Inspection of Butt-welds in PipingButt-welds in piping and in API Std 650 horizontal tank 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.
storage tanks API Std 650 horizontal tank designed in accordance with the rules and guidelines of API 650 are called API 650 storage tanks. API 650 is a control rule for welded storage tanks that work normally in the normal pressure range.
Oil storage tank is an important equipment commonly used in petroleum and petrochemical industry. New API Std 650 horizontal tank, metal storage tank must be tested before it can be put into use or put into storage. The common inspection methods of API Std 650 horizontal tank include radiographic testing, ultrasonic testing, magnetic particle testing and dye penetrant testing. The parts and operation requirements of these testing methods are different, so they should be selected according to the required characteristics.
