Specialized Tank Services – Expert Solutions

Ultrasonic permeation detection is a non-destructive testing method that uses high-frequency sound waves to identify minute permeations, pinholes, and areas of wall thinning in tank walls and bottoms that are completely invisible during visual inspection. This technology is critical for regulatory compliance under EPA and state environmental regulations, particularly for underground storage tanks. It helps facility owners make informed decisions about whether a tank requires targeted repairs or full replacement, often preventing catastrophic leaks and environmental incidents. Our technicians use calibrated ultrasonic testing equipment to create detailed thickness maps, documenting the structural condition of your tank and providing the data needed for API 653 inspections, insurance requirements, and regulatory reporting.

Yes, manway retrofitting is one of our core specialized services. Many older tanks were constructed without adequate human access points, making future inspection, cleaning, and maintenance extremely difficult or impossible without cutting into the tank structure. Our certified welding crews install industry-standard 22-inch diameter manways with secure 18-bolt covers onto both single-wall and double-wall steel tanks. The retrofit process includes structural assessment, precise cutting and edge preparation, full-penetration welding performed to API and ASME standards, pressure testing to verify integrity, and final coating or lining of the welded area. This code-compliant access point enables future inspection and maintenance work while significantly extending the useful service life of your tank asset.

The Genesis system is AmTech's proprietary solution for converting existing single-wall underground storage tanks into fully compliant double-wall tanks with interstitial monitoring capability—without excavation or tank replacement. We install a secondary containment barrier inside the existing tank shell, creating a monitored interstitial space between the two walls. This system meets current EPA and state environmental regulations for secondary containment and leak detection, allows facilities to continue operating aging tank infrastructure safely and legally, and saves tens of thousands of dollars compared to excavation and new tank installation. The Genesis system is compatible with petroleum fuels, alcohol-blended fuels (E10, E15, E85), biodiesel, and various petrochemical products, making it an ideal regulatory compliance solution for fuel retailers, fleet operators, and industrial facilities.

Project duration varies significantly based on the specific service and scope. Ultrasonic permeation detection surveys typically require 1-3 days depending on tank size and the number of units being tested. Manway retrofitting projects generally take 3-7 days including welding, testing, and interior surface restoration. Genesis double-wall retrofit installations typically require 1-2 weeks depending on tank size, configuration, and site-specific conditions. Emergency specialized services can often be mobilized within 24-48 hours with expedited timelines. During our initial assessment, our field engineers provide detailed project timelines that account for your facility's operational requirements, regulatory deadlines, and any necessary coordination with local authorities or inspectors.

Most specialized services require temporary tank decommissioning for safety and proper execution. Ultrasonic testing requires the tank to be emptied and cleaned to allow proper sensor contact with interior surfaces. Manway retrofitting involves welding and cutting operations that mandate tank emptying, purging, and gas-free certification. Genesis double-wall retrofits require complete tank preparation and interior access for secondary barrier installation. However, our experienced crews work efficiently to minimize downtime—often completing projects during scheduled maintenance windows or facility shutdowns. We coordinate closely with your operations team to develop work schedules that minimize business disruption. In some cases, we can provide temporary storage solutions or phased work approaches that maintain partial facility capacity during the project.

Yes, all AmTech specialized services are backed by our industry-leading Blue Check warranty program. Warranty coverage varies by service type: structural modifications like manway retrofits carry warranties on welding integrity and structural performance; Genesis double-wall installations include warranties on the secondary containment barrier system and monitoring components; and specialized repairs include coverage on materials and workmanship. Warranty terms range from 5 to 20 years depending on the specific service, tank conditions, and operating environment. Unlike many competitors who rely on manufacturer warranties alone, AmTech stands behind our specialized work with direct warranty coverage, technical support, and rapid response if any issues arise during the warranty period.

In many cases, yes—specialized services can bring aging tank systems into full regulatory compliance without costly replacement. Our Genesis double-wall retrofit specifically addresses EPA secondary containment requirements for underground storage tanks. Manway retrofitting enables code-compliant access for required inspections under API 653 and state regulations. Ultrasonic permeation detection provides the documented structural integrity data required by insurance carriers and regulatory agencies. However, compliance feasibility depends on the tank's current condition, the specific regulations that apply to your facility and location, and whether the tank substrate has sufficient remaining integrity to support retrofits. During our initial engineering assessment, we evaluate your tank against all applicable federal, state, and local requirements and provide clear recommendations on whether specialized services can achieve compliance or if replacement is the more appropriate path.

Our specialized services apply to a wide range of tank configurations and materials. Ultrasonic permeation detection works on steel, fiberglass, and FRP tanks both above-ground and underground. Manway retrofitting is performed on steel tanks including single-wall and double-wall underground storage tanks, above-ground atmospheric storage tanks (ASTs), and process tanks. The Genesis double-wall retrofit system is specifically designed for steel underground storage tanks holding petroleum products and fuels. We work with tanks ranging from small 500-gallon units to large industrial storage vessels exceeding 50,000 gallons. During our assessment phase, our engineers evaluate whether your specific tank configuration, material, stored substance, and current condition make it a good candidate for specialized services or whether alternative solutions would be more appropriate.
