API 650 cylindrical welded storage tanks for liquid products storage

API 650 internal floating roof oil tank executive standard: domestic design standard: GB50341-2003 "Vertical cylindrical steel welded oil tank design code"; domestic construction standard: GB50128-2005 "vertical cylindrical steel welded oil tank" Construction and Acceptance Specification; API 650 cylindrical welded storage tanks Foreign design standard: API650-2007 "Standard for Welded Steel Petroleum Storage Tanks."

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 cylindrical welded 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.

The specifications used in the design of large oil tanks, API 650 cylindrical welded storage tanks mainly include American Petroleum Institute Standard API 650, Japanese Industrial Standard JIS B8501, British Industrial Standard BS2654 and Chinese National Standard GB50341 from a global perspective. The formulas used in each specification are based on the hoop stress in the membrane theory. Each specification is based on the performance characteristics of materials and the construction technology level of their respective countries to determine the allowable stresses and weld coefficients. Therefore, the calculation results of tank wall thickness of API 650 cylindrical welded storage tanks with the same volume are sometimes quite different according to different specifications.

We have a stable system and professional human resource management work as the support, from the six aspects of guidance, cohesion, incentive, constraint, radiation and stability, we continue to introduce, modify and train employees from concept to action, and shape employees through constant guidance of common values.
