Certified API 653 Tank Inspectors
All API 653 inspections are performed by certified inspectors with extensive experience in refinery, petrochemical, and industrial storage environments. Our team understands the construction, service conditions, and degradation mechanisms commonly affecting aboveground storage tanks.
We work closely with facility owners, operators, and engineering teams to plan inspections efficiently, coordinate tank access, and maintain strict safety standards throughout the inspection process.
Chem Ref Services offers a full range of API 653 inspection capabilities tailored to your tank’s design, contents, and operating conditions.
We perform detailed internal and external inspections to evaluate tank shells, bottoms, roofs, nozzles, and structural components. Inspections identify corrosion, deformation, cracking, and other conditions that may impact tank integrity or service life. The primary purpose of an internal inspection of an aboveground storage tank is to assess the condition of the tank bottom floor and identify deterioration that could lead to leakage or failure. We address the soil-side corrosion, using visual assessments, UT thickness measurements, and Magnetic Flux Leakage (MFL) floor scanning.
Our inspectors conduct settlement evaluations to identify uneven foundation movement that could compromise tank stability. Settlement analysis helps prevent shell distortion, bottom damage, and long-term structural issues.
We perform accurate thickness measurements and NDE testing to detect metal loss, corrosion, and hidden defects. These inspections support remaining life calculations and help determine appropriate inspection intervals.
Chem Ref Services provides weld inspection and repair oversight to ensure all tank repairs meet API 653 requirements. We verify workmanship, materials, and procedures to support safe and compliant repairs.
We prepare complete API 653-compliant inspection reports required for regulatory review, insurance audits, and internal records. Our documentation is clear, organized, and designed to support long-term asset integrity management.
