API standard 650 welded steel storage tanks welding electrodes

If additional requirements are met, higher internal pressures are allowed. API 650 only covers tanks that support the whole bottom evenly and API standard 650 welded steel storage tanks tanks in non-refrigerated service that have a maximum design temperature of 200 degrees F. It requires that you have a minimum material thickness of 3/16 inch.

Anti corrosion of API standard 650 welded steel storage tanks:
After using for a certain period of time, it is necessary to check the corrosion protection of the API standard 650 welded steel storage tanks. If necessary, the outer wall of the metal oil tank should be painted with new anti-corrosion paint to ensure that the outer wall of the API standard 650 welded steel storage tanks does not fall off and has good waterproof and rust resistance.
API standard 650 welded steel storage tanks cleaning:
The long-term use of API standard 650 welded steel storage tanks will produce impurities on the tank wall and deposit on the tank bottom, resulting in tank corrosion to leakage. According to the safety standard of oil tank, the API standard 650 welded steel storage tanks shall be cleaned and derusted regularly to ensure the quality of oil stored and the safety of oil tank equipment.

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 welded steel 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.
