Self Bunded Tanks must meet a series of strict standards and undergo comprehensive testing to pass compliance checks. These processes ensure that the tanks are safe, reliable, and environmentally friendly.
Structural Integrity Testing
Manufacturers typically start with structural integrity tests. Hydrostatic testing is commonly used, where the tank is filled with water to a specified pressure. This pressure simulates the maximum load the tank will endure during normal operation. Any deformation, leakage, or signs of weakness indicate a failure. Additionally, the tank’s material quality is closely examined to ensure it meets the required standards. CORTEN steel, for example, must possess the appropriate chemical composition and mechanical properties.
Leak Detection Testing
Leakage is a major concern, and thus, thorough leak detection tests are mandatory. Sensors installed in the interstitial space between the inner and outer tanks are tested for functionality. Manual leak tests are also carried out, often using tracer gases or specialized leak - detection fluids. If a Self Bunded Tank is designed to store hazardous substances, the sensitivity of the leak detection system must meet higher standards.
Ventilation and Pressure Relief Testing
Testing of ventilation and pressure relief systems is crucial. Pressure relief valves are calibrated and tested to ensure they open and close at the correct pressure thresholds. Ventilation systems are checked for proper airflow and functionality. Blockages or malfunctions can lead to over - pressurization, posing significant risks.
Documentation Review
Regulatory bodies also review comprehensive documentation. This includes design blueprints, material specifications, manufacturing records, and maintenance logs. All records must be accurate, up - to - date, and compliant with relevant regulations. Records of regular inspections, repairs, and replacements are especially important, as they demonstrate the tank’s ongoing compliance.
Environmental Compliance Checks
Finally, Self Bunded Tanks must meet environmental standards. This may involve assessing the tank’s potential impact on soil, water, and air quality in case of a leak. Compliance with these standards helps prevent pollution and ensures the overall safety of the surrounding environment
