API 653 Inspectors: Ensuring Integrity in Above Ground Storage Tank Inspections
Introduction
NVI, a leader in the field of Non-Destructive Testing (NDT) services, recognizes the critical role that above ground storage tanks (ASTs) play in various industries, including oil & gas, chemical, and petrochemical sectors. Ensuring the mechanical integrity of these tanks is not just a regulatory requirement but a fundamental necessity to maintain operational safety and efficiency. This is where API 653 Inspections come into play, and NVI’s certified API 653 inspectors are at the forefront of delivering excellence in AST inspections.
Understanding API 653 Inspections
API 653, “Tank Inspection, Repair, Alteration, and Reconstruction,” is a standard developed by the American Petroleum Institute (API) that outlines the methodology for maintaining the integrity of above ground storage tanks. It specifies the inspection procedures, repair guidelines, and reconstruction practices for safe tank operation. API 653 inspections are a critical component of a comprehensive mechanical integrity program, ensuring that tanks meet the necessary safety and reliability standards.
The Role of API 653 Inspectors
API 653 Inspectors are certified professionals equipped with the knowledge and skills to perform detailed inspections of ASTs. They play a pivotal role in identifying potential issues that could compromise tank integrity, including corrosion, leakage, structural failures, and foundation problems. By adhering to API 653 guidelines, inspectors help facility owners ensure their tanks are in compliance with industry standards and regulations.
Key Components of API 653 Inspections
- External Inspection: Evaluates the tank’s overall condition from the outside, including the foundation, shell, roof, and attachments. External inspections can identify visible signs of leaks, corrosion, and structural distress.
- Internal Inspection: Provides a comprehensive assessment of the tank’s internal components, such as the bottom, shell, and roof from the inside. It focuses on detecting corrosion, pitting, cracking, and other material deficiencies.
- Ultrasonic Thickness Testing (UTT): An essential part of API 653 inspections, UTT measures the thickness of tank walls to assess material loss due to corrosion or erosion.
- Settlement Evaluation: Inspects the tank’s foundation and overall alignment to identify any settlement issues that could affect the tank’s structural integrity.
Benefits of API 653 Inspections
- Safety and Compliance: Ensures ASTs are safe for operation and compliant with regulatory standards.
- Preventive Maintenance: Identifies potential issues before they lead to significant problems, reducing the risk of environmental incidents and costly downtime.
- Extended Equipment Life: Regular inspections and maintenance can extend the lifespan of storage tanks, optimizing the return on investment.
- Operational Efficiency: Maintains the reliability and availability of storage facilities, supporting uninterrupted plant operations.
