APEX INTEGRITY INSPECTIONS conducts in-service inspections—also known as external inspections—while tanks remain operational or when internal access is not possible. These inspections involve a detailed visual assessment of the tank’s exterior to identify leaks, shell distortion, settlement, corrosion, and the condition of coatings, insulation, and appurtenances.

At APEX, we adhere to the American Petroleum Institute (API) Standard 570—the industry’s benchmark for the inspection, repair, and modification of process piping systems. This standard applies to piping that is in service or temporarily out of service with the potential for future use. It excludes decommissioned systems and specialized equipment.

Closed Interval Survey (CIS) is a specialized technique used to assess the effectiveness of cathodic protection systems on buried pipelines. This method involves measuring the pipe-to-soil potential at closely spaced intervals along the pipeline route, typically every few feet. The data collected helps identify coating defects, areas of corrosion, and other anomalies that may compromise pipeline integrity.

Fitness for service (FFS) assessment is a multi-disciplinary engineering analysis to determine whether the equipment is fit for continued service- typically until the next shutdown or repair opportunity.

APEX Integrity offers comprehensive NDT services to ensure asset reliability and safety without causing damage.

Our certified inspectors use advanced techniques including:

Large petroleum, gasoline, and chemical storage tanks require tank calibration services to measure and verify quantities and volume. Calibration is the process of calculating the precise volume of your tank using established measurement standards. This procedure is essential for acquiring precise amount measurements and maintaining positive contractual relationships with clients, regulating authorities, and insurance companies.

At APEX, our Welding Inspection services are designed to ensure the highest standards of quality, safety, and compliance in welded structures and components. We apply internationally recognized codes and standards (such as ASME, AWS, and ISO) to assess the integrity of welds across various industries, including oil & gas, petrochemical, power generation, and construction.

At APEX, we provide specialized Liquefied Petroleum Gas (LPG) services designed to uphold the highest standards of safety, compliance, and operational excellence.

Our comprehensive LPG service offering includes:

The Direct Current Voltage Gradient (DCVG) Survey is a proven technique used to detect and evaluate coating defects on buried pipelines. By measuring voltage gradients in the soil above the pipeline, DCVG identifies areas where protective coatings may have deteriorated, allowing for targeted maintenance and repair.

Out-of-service (internal) tank inspections involve thorough evaluations of all accessible internal and external tank components by certified inspectors. These inspections, requiring tanks to be taken offline, assess structural integrity, detect leaks, corrosion, and potential environmental hazards. Key areas such as tank shells, roofs, piping, and appurtenances are examined using various NDE techniques.
