If a bolted or welded steel tank is being used, over time, corrosion is an enemy. Regardless of how secure the containment choice, the best steel tanks experience increasing corrosion and eventually fail if they do not regularly undergo tank inspections and preventative maintenance services.
Steel storage tanks are subject to requirements and regulations that make repairs, retrofits, and upgrades a necessity. When tasked with storing new products, welded steel tanks may experience degradation and loss of life of service. Some powder-activated carbon used in meeting federal standards to reduce mercury reacts with steel silos and vessels that contain them and cause the steel to degrade. To maintain service life and long-term integrity, power plants have steel silos restored and ensure EPA Mercury and Air Toxics Standards compliance.
Multiple Steel Tank Repair Options
There is a range of steel tank repair options. For a long time, the only option for containing certain products was a rubber lining. Steam curing applications are expensive, especially on large tanks. Many welded and bolted tanks may have a coating system installed that works well for a time.
When it is time to replace them, repair service personnel often suggest replacing the original coating with a lining system. Coatings are adequate when a paint-like, thin mil system is all that is required. Like paint, coatings have no apparent structural integrity. In some cases, as part of a substrate-bonded system, they meet the needs of specific jobs.
Linings generally provide a longer protection window for tanks. They provide structural integrity and do not disband as coating systems tend to do. A lining applied to a substrate that is adequately prepared eliminates the risk of blistering caused by osmotic forces. Any lining puncture is less likely to spread past the intrusion. The damage and repairs are contained in a specific area. Across the board, tank linings offer long term protection of the investment made and offer an extended service life.
Durable Steel Tank Linings
One hundred percent of solids systems have revolutionized tank lining. With the high-temperature, high-build spray-up application, storage tanks are covered with a thick and bonded wall. This type of lining is compliant with all California regulations and requirements. Our California storage tank repair services use the lining for commercial, municipal, and industrial applications for:
- Department of Defense
- Department of Homeland Security
- Food Processing Plants
- Fortune 500 Companies
- Oil and Gas Industry
- Power Generation Plants
- Wastewater Facilities
- Water Utilities
Custom Solutions for Bolted and Welded Tanks
Engineering expertise has set the standard for inspection and cost-effective repairs. 
Our experienced crews can repair and restore tanks to exceed the original design specs or to retrofit for new uses. Our California crews have vast knowledge and experience of tank materials, performance, and construction.
We provide skilled repairs, modifications, and maintenance services that keep a tank in top condition with little disruption in business. Common repair projects are:
- Bottom replacements
- Floating roof seal replacements
- Pit welding of corroded areas
- Roof plate replacement and repair
- Shell patches or replacements
Bolted and welded tanks store carbon powder, petrochemicals, gasoline, oil, leachate, wastewater, fire suppression water, potable water, and other materials. Tank repair services provide turnkey repairs and lining solutions tailored to the need of the tank.
Our California engineering teams are ready to provide service for those who require water storage tanks to be repaired or modified. Our fully equipped fabricating facilities have extensive inventories of assorted fittings, pipes, and plates that allow them to respond cost-effectively and quickly for any modification or repair project.
Types of modifications include:
- Adding nozzles and other fittings
- Increasing tank capacity
- Installation of double bottoms
- Installation of a new floating roof
- Leak detection and secondary containment
- Tank relocation
If there is a tricky design that requires fresh ideas, our California staff is ready to provide a creative tank fabrication service. Services include designing and building water storage tanks and other types of tanks that include custom straps and mounting brackets.
We fabricate containers that range in capacity from 50,000 to 250,000 gallons specializing for a project’s needs, whether the container is a water storage tank or a storage tank needed for the oil or agriculture industry. Tank inspections are made to test containers for integrity when making repairs. We take into consideration the design, configuration, and size of the container. Our integrity tests include:
- Visual Inspection
- Acoustic emissions testing
- Ultrasonic testing
- Radiographic testing
- Hydrostatic testing
- Other systems of non-destructive testing.
