Service Conditions and Hydrogen-induced Cracking
When the service conditions might include the presence of hydrogen sulfide or other conditions that may promote hydrogen-induced cracking effects, particularly near the bottom of the API 650 welded steel storage tanks shell at the shell-to-bottom connections, care shall be taken to ensure that the materials and details of construction of the tank are adequate to resist hydrogen- induced cracking. The Purchaser shall consider restricting the sulphur content of the material to be stored through thickness testing of the steel, laboratory surveillance tests, and the use of internal tank coatings to reduce the possibility of hydrogen-induced cracking.

After using for a certain period of time, it is necessary to check the corrosion protection of the metal oil tank and paint the outer wall of the API 650 welded steel storage tanks with anti-corrosion paint. The inlet and outlet valves of API 650 welded steel storage tanks shall be inspected and maintained regularly to ensure they are in good condition. Oil tank will produce a lot of dirt when it is stored for a long time. Usually, the cleaning cycle of metal oil tank is about three to five years.
