ASTM A1011 grade 33 sheets API standard 650 aboveground steel oil storage tanks

API 650 is the standard for welded tanks for oil storage. It specifies the API standard 650 aboveground steel oil storage tanks design, manufacturing, welding, inspection and installation requirements of oil tanks. API 650 is widely used in storage tanks with internal pressure less than or equal to 2.5 PSI.

API standard 650 aboveground steel oil storage tanks, Oil tank is a large-scale storage equipment used to store oil materials. Usually, the service life of API standard 650 aboveground steel oil storage tanks is related to the actual working conditions. The design service life of most oil tanks is 20 years, and some of them are 10-15 years. Generally, none of them is less than 10 years. However, the design service life of API standard 650 aboveground steel oil storage tanks is on the one hand, which is an ideal state, but there are many objective factors in the actual process, it is impossible to achieve the designed service life. How to effectively increase the service life of API standard 650 aboveground steel oil storage tanks?

API 620 Crude Oil Tank Non-pressure Parts
Welds for pads, lifting lugs, and other nonpressure parts, as well as temporary lugs for alignment and scaffolding attached to primary components, shall be made in full compliance with a welding procedure qualified in accordance with Q.6.1. Lugs attached for erection purposes shall be removed, and any significant projections of API standard 650 aboveground steel oil storage tanks weld metal shall be ground to a smooth contour. Plate that is gouged or torn in removing the lugs shall be repaired using a qualified procedure and then ground to a smooth contour. Where such repairs are made in primary components, the area shall be inspected by the liquid-penetrant method. A visual inspection is adequate for repairs in secondary components.
