Inspection & Testing of Above-Ground Tanks

Our versatile above ground storage tank inspection company handles all tanks, including those holding hazardous materials. Tarsco’s specialists carry out ultrasonic thickness checks, corrosion tracking, and coating evaluations to keep your tanks in line with NFPA 22/25.

A typical project ends with a detailed report consisting of our findings, structural upgrades, and retrofit recommendations tailored to your unique site. This highly detailed approach clearly spots any potential issues, thus helping you avoid costly failures and maintain safe, compliant operations. We aim to support proactive maintenance, minimize your downtime, and extend the working life of critical tank assets.

Our Storage Tank Inspection & Testing Services

Inspection Process & Standards

Comprehensive Assessment

We examine each tank through close visual checks and precision ultrasonic testing to uncover leaks, thinning steel, or hidden deformation.

Damage Detection

Our professional inspectors look for any corrosion, flow dents, pitting, weld stress, or overpressure fatigue so that you can address the problems before they compromise safety.

Regulatory Compliance

Every inspection we carry out is in accordance with NFPA 22/25, API 653, and related codes to meet permitting and insurance requirements.

Detailed Reporting

All sites receive a full package of findings, including thickness readings, photographs, and engineering notes to support your maintenance or retrofit planning.

Testing & Support Services

Ultrasonic Thickness Testing

We incorporate advanced instruments that map steel plate thickness across shells and floors to reveal wear points long before they threaten integrity.

Hazardous Material Tank Inspections

We have devised specialized procedures that safeguard our crews and sites while evaluating tanks that store regulated products.

Coating Evaluations

Internal and external linings are also tested for adhesion, permeability, and chemical resistance to verify continued protection against corrosion.

Engineering Integration

All our test results are fed directly into structural calculations and retrofit designs, giving owners clear, actionable data for life-cycle maintenance.

Our Process for Tank Inspection & Testing

With us, each above ground storage tank inspection begins with a site-specific review of operational history and regulatory requirements. Our crews develop an inspection plan, perform visual and ultrasonic testing. After we compile the data into a certified report, the findings are reviewed to schedule repairs or retrofits that minimize downtime and preserve long-term tank performance.

FAQs About Tank Inspection & Testing

Compare our tank types to find the best solution for your specific application requirements

For atmospheric storage designed to AWWA/API, bolted tanks meet the same loads (hydrostatic, wind, seismic). Welded tanks are preferred for pressure service or extreme temperatures. Strength depends on code, thickness, and detailing - not the joint type alone.
They can be. Benefits include recyclable steel, factory coatings with low/zero VOCs, fast installation with less site disturbance, long service life, and the ability to disassemble, relocate, or expand.
Absolutely. Our above ground storage tank inspection services are customized for water, chemical, food-grade, television, and motion picture applications or fuel tanks to address unique operating conditions and product hazards.
Our experts can easily carry out certain tank inspection tasks, such as external visual checks and ultrasonic testing, while your tank remains in operation. However, for internal inspections, we typically require the tank to be empty and gas-free.
Properly designed and erected, no. Gasketed seams, controlled bolt torque, quality coatings/liners, and hydrostatic testing deliver tightness. Periodic inspections and gasket replacement maintain long-term performance.
Yes. Our clients receive PE-stamped engineering reports, ultrasonic data sheets, and photographic documentation. Additionally, you get product viability studies and development, design calculations, and engineering drawings.
Most tanks require a professional, full storage tank inspection every 3–5 years. It also depends on the service conditions and regulatory codes, such as API 653 and NFPA 22/25. An annual inspection is also recommended for added safety.
We design, manufacture, and build bolted steel tanks for clients worldwide, with projects delivered across North America and beyond.
Tarsco inspectors are trained to ASTM, AWWA, FDA, NSF, NFPA, and FM standards, as per top industry norms. They also carry OSHA safety certifications for confined-space entry and non-destructive testing.
