Industrial Asset Management Made Simple

Our Inspectors are certified ASNT-SNT-TC-1A Non-Destructive Testing (NDT) technicians. Our NDT methods yield in-depth quantitative results, allowing us to calculate corrosion rates and find areas of excessive deterioration. We can then recommend the preventative maintenance needed to mitigate the probability of a hazardous discharge into the environment and avoid more costly repairs later on.

We perform both fixed interval inspections and risk-based inspections to provide insight into the structural integrity of your assets when it is most needed. Our expert API 653, API 510, STI SP0001, and API 570 inspections will uncover exactly how well your tank is holding up, to both outside elements and the product it contains.

Why Oklahoma is Choosing NDT Tanknicians

The Sooner State is at the center of the Mid-Continent oil region. Like its neighboring states, the oil and gas industry in Oklahoma remains a significant economic driver. But Oklahoma’s impact on commerce reaches far beyond its state borders. Since 1912, the city of Cushing has been an influential site for the global oil industry. The “Pipeline Crossroads of the World” has a storied history of oil booms and refinery operations. Today, the city and the surrounding area houses enough storage tank farms to contain nearly 100 million barrels of oil and acts as the delivery location for West Texas Intermediate grade of crude oil. The location provides essential connections between consumers in upper North America with oil producers in the south and around the Gulf of Mexico.

The energy sector in Oklahoma is frequently near the top employer in the state with substantial economic impact. Chesapeake Energy Corporation, Devon Energy, SandRidge Energy are all headquartered in Oklahoma City while NGL Energy Partners LP, Williams and ONEOK are based in Tulsa. Significant oil fields such as the Sho-Vel-Tum Field and the Cushing-Drumright Field have historically driven production in the region. In western Oklahoma lies the Hugoton Gas Area, one of the largest natural gas fields in the nation. A vast network of long distance pipelines carries the gas across the state and throughout the United States. Oklahoma is also investing in emerging and sustainable energy sources such as wind, solar, and biomass. In late 2021, the Hydrogen Production, Transportation, and Infrastructure Task Force released a report noting Oklahoma’s strong potential for producing hydrogen.

NDT Tanknicians is ready to provide exemplary, non-destructive testing services to Oklahoma businesses with storage tank inspection needs. Our team has the knowledge and on-the-ground experience to ensure our clients’ assets are protected and the structural integrity of their infrastructure is sound. Oklahoma’s climate is a combination of humid and subtropical in the east and semi-arid in the west. Each environment poses unique challenges and stressors on storage tanks and pressure vessels. The state sees an average of 57 tornadoes a year and a recent spike in seismic and earthquake activity are new challenges for petrochemical and asphalt companies in Oklahoma. NDT Tanknicians is ready to help our clients meet these challenges.

With NDT Tanknicians, Oklahoma businesses can have the peace of mind of knowing that the mechanical integrity of their assets is our top priority. In addition to our non-destructive tank inspections, we provide high-quality coating and lining services which protect against humidity-related degradation. Our highly-trained, certified technicians will ensure our clients are meeting federal and local standards and that their infrastructure is secure.
