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 Std 650 cylindrical 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.

During heavy rain, closely observe the change of the water level in the storage area of the API Std 650 cylindrical tanks. If the water level rises to the dangerous range, drain the water immediately. There are more thunderstorms in heavy rain, and lightning protection devices should be installed in the API Std 650 cylindrical tanks area to avoid lightning accidents. Observe the groundwater level of the API Std 650 cylindrical tanks area at any time, clean and dredge the drainage ditch in time to ensure unobstructed drainage, and prevent the bottom of the API Std 650 cylindrical tanks from leaking and rusting due to untimely drainage.
