API 653 Tank Inspection, Repair, Alteration, & Reconstruction

Prime Inspections follows API 653 as the standard for non-destructive testing of aboveground storage tanks, ensuring they meet the stringent standards set by the American Petroleum Institute (API). These vital services detect potential weaknesses, corrosion, and anomalies in tank structures, safeguarding against leaks and failures. By adhering to API 653 guidelines, industries benefit from prolonged tank lifespans, optimized safety, and reduced environmental risks. NDT services under this standard are indispensable for any facility aiming to maintain compliance, ensure operational efficiency, and uphold their reputation in the petroleum sector.
