    Design Code for Buried Tanks – UL-58 or ASME VIII?

    I have been searching the appropriate design codes applicable to these buried tanks, and based on my findings, a single standard is not sufficient to cover all aspects of the design. The civil layout and installation approach will be similar to the drawing shown (taken from a previous project)...

    Design Code for Buried Tanks – UL-58 or ASME VIII?

    Thank you for your input. Your point about fabrication and transport is spot on, especially since we’re designing a total of five tanks of this size. Shop fabrication and delivery logistics are definitely a major concern in this case. Additionally, external pressure from soil and flotation due...

    Subject: Dyke Wall Capacity Criteria as per NFPA/OGRA – Class-wise Tank Scenarios in General Plot Plan

    Thank you for highlighting these important points — really appreciate it. At the moment, I'm specifically working on dyke sizing for a project, so my focus has been on reviewing the applicable guidelines and volume requirements. But you're absolutely right — dyke containment is just one layer...
