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 Colorado is Choosing NDT Tanknicians

Business is booming around the Southern Rocky Mountains and The Great Plains. Colorado houses over 6000 manufacturers operating across a range of industries. In 2019, FitSmallBusiness.com named Colorado the #2 State to Start a Cannabis Business and the US Energy Information Administration ranked it #7 in their list of the Top 10 Energy-Producing States. The energy and natural resources sector alone contributes over $10 billion annually to Colorado’s economy and supports over 100,000 workers. Colorado ranks 5th in terms of crude oil production nationwide, and the Colorado Asphalt Pavement Association is made up of more than 250 member organizations operating over 60 production facilities. NDT Tanknicians has a keen understanding of the unique needs of businesses operating in the beautiful state of Colorado. Its mountainous, desert, plain, and foothill regions range from semi-arid to humid subtropical, including alpine, Mediterranean, and subarctic regions. In certain areas of the Front Range foothills, storage tanks face the risk of humidity-related corrosion, while vessels in the Eastern Plains may be damaged during the region’s record-breaking hail storms or flash floods. Spring melts in the state’s mountainous region can cause additional flooding around the Colorado River, the Rio Grande, the South Platte River, and other bodies of water. In addition to its numerous petroleum storage tanks and pressure vessels, the Centennial State is home to a large number of water towers.These structures are vulnerable to a range of climate-related degradation alongside normal wear-and-tear. Alongside our tank inspection services, we are proud to offer our Coloradan customers expert tank coating and lining services to help protect and defend against weather-related damage. We also provide high-quality repair and engineering services, and we stand by our work.
