- In September 2017, TesTex was contracted by a southern Nuclear Facility to perform theTesTex LEFT (Low Frequency Electromagnetic Technique) on an above ground storage tank. The tank was a 40 foot diameter by 30 foot high tank containing filtered water. The lower ring on the tank was .232” Carbon Steel and the upper rings were .1875” Carbon Steel. The basis of the examination was to assist the utility in making a decision as to either repair the tank or replace it. This particular tank has had many leaks and repairs over the years. So the plan was to scan as much of the tank as possible with LFET and present the results to engineering so they could make a determination as to what the next step would be. As it turns out the TesTex LFET found so many indications of pitting that only ¾ of the lower ring was inspected. Needless to say the lead Engineer was very pleased with the TesTex inspection. She told the crew that she will definitely be looking to bring TesTex back in to inspect other tanks onsite.
Nuclear Storage Tank Inspection

- TesTex is pleased to announce the renewal of our Pennsylvania Department of Environmental Protection (PADEP) certification for above ground storage tank inspections of manufactured and field erected bulk storage tanks and terminals. TesTex has over 30 years of tank inspection experience with several inspection tools to make your tank inspection fast accurate and cost effective. Our Falcon S saturation eddy current floor scanning technology virtually eliminates the need for ultrasonic thickness prove up of indications. The automated mapping technology provides detailed X and Y coordinates of every indication reported in our findings. For weld inspections we have replaced vacuum box and magnetic particle testing by utilizing our Hawkeye crack detection tool based on a Balanced Field Electromagnetic Technique which works through coatings, rust and epoxies on your equipment. This technology identifies surface and sub-surface cracks in your welds and heat affected zone. For shell course examinations we can do away with the need for a JLG or scaffolding of the storage tank, with the Viper magnetic tank crawler that can scale the outside of the tank and record all the necessary thickness readings for your inspection. The Crawler has also been successfully applied to tank roofs for thickness readings as well. Of course all this technology is available and utilized by our staff of API 653 certified technicians.

- At 2:39 PM on a Wednesday afternoon TesTex was alerted by one of our nuclear customers that they had an emergency inspection request when they discovered two leaks in a 20” buried service water line. The leaks occurred in an area where a repair clamp was installed a few years ago. The customer was asking if we could mobilize a crew and equipment at a moment’s notice to perform a Low Frequency Electromagnetic Technique (LFET) inspection on the adjacent areas of the pipe to determine further degradation of the system. The LFET technology permits scanning through coatings that are applied to the water line where other technologies were limited or not able to provide the information they required. Communication with the customer continued into the late evening when it was agreed that TesTex would deploy inspection personnel and LFET equipment at 6:00AM, the next morning, a mere 16 hours after the emergency call from the customer. The customer events and dynamic response that TesTex demonstrated are typical of our commitment to provide Fast, Accurate, and Cost Effective inspection solutions for our customers. See our Products page for more information on LFET.
