The environmental and water treatment industry relies on robust and reliable infrastructure. For underground storage of hazardous materials and clean water, double-wall tanks with cathodic protection are a preferred choice. The Steel Tank Institute (STI), a leading organization dedicated to promoting safe and effective steel tank technology, has developed a comprehensive standard, Sti-P 3, specifically addressing these critical components.
Sti-P 3: The Standard for Double-Wall Underground Tanks with Cathodic Protection
Sti-P 3 is a valuable resource for engineers, contractors, and regulatory agencies involved in the design, installation, and maintenance of double-wall underground tanks. This standard outlines the minimum requirements for:
Benefits of Sti-P 3 Compliance:
Conclusion:
Sti-P 3 serves as a comprehensive guideline for the design, installation, and maintenance of double-wall underground tanks with cathodic protection. By adhering to this standard, stakeholders can ensure the safety and reliability of critical infrastructure, safeguarding the environment and protecting public health. This standard promotes responsible and sustainable practices in the environmental and water treatment industry, contributing to a cleaner and safer future.
