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 Petrochemical Companies in San Francisco, Oakland, and San Jose are Choosing NDT Tanknicians

NDT Tanknicians understands the challenges faced by industrial companies in Northern California. While the Bay Area’s five major sea ports connect the region’s manufacturers and suppliers to national and international markets and logistics, the salt water of the San Francisco Bay increases the oxidation rates and corrosion of storage tanks in the area and may shorten the lifespan of crucial materials. Coating failure can be a major issue in this area. In addition to tank inspections, NDT Tanknicians offers high-quality anti-corrosive coating and lining services, safeguarding the future of your assets, as well as repair services to remedy existing areas of corrosion.

Thanks to the crude fields in the San Joaquin Valley and the Los Angeles Basin, oil and gas is a major industry in California. Over 20 giant oil fields operate in San Joaquin Valley, including the largest in the state, the Midway-Sunset oil field. Altogether, the region has produced over 1 billion barrels of oil. Incidents such as the 2012 Chevron refinery fire and 2015 ExxonMobil Refinery explosion underline the importance of professional testing and inspections. Following the 2007 Cosco Busan oil spill in the San Francisco Bay, 8 different bills related to oil spill response were signed into law, including bills requiring more stringent oversight of California’s oil-producing facilities. We are seriously committed to supporting the safety and structural integrity of your assets.
