API Std 650 welded tanks for oil storage vents
The API Std 650 welded tanks for oil storage external floating roof tank of API 650 tank has many advantages, and its application range is more and more wide. It is a kind of storage tank with a bright future. The well-designed internal floating roof tank of API 650 tank is the best and least investment method to control evaporation loss of API Std 650 welded tanks for oil storage Fixed roof tank.
Ultrasonic testing can find the internal defects of API Std 650 welded tanks for oil storage welding joint, this detection method is very accurate for the internal layer defects of oil tank, but ultrasonic detection is not suitable for the detection of thin-walled storage tank materials. Dye penetrant testing is only suitable for detecting the defects of the surface opening of API Std 650 welded tanks for oil storage and so on metal oil tanks. The feature of this method is convenient and fast.
Impact Test Requirements for Oil Storage Tanks Primary ComponentsAll API Std 650 welded tanks for oil storage primary components of 9% or 5% nickel steel shall be impact tested in accordance with Q.2.2.2 through Q.2.2.4. Impact testing is not required for primary components of austenitic stainless steel, nickel alloy, and aluminum materials. Welds in high-alloy (austenitic) stainless steel shall be impact tested if required by Q.6.3.Impact testing of plates, including structural members made of plate, shall comply with the following:a)Impact test specimens shall be taken transverse to the direction of final plate rolling. b)Charpy V-notch specimens shall be cooled to a temperature of –320°F for A353, A553, and A645 steels for impact testing.
