Offering a combination of strength and longevity, Carbon fiber based composites are becoming a popular technology for repairing industrial tanks. Advanced FRP Systems has a wide range of corrosion prevention and structural rehabilitation solutions utilizing carbon fiber composites. Because of carbon fiber’s ability to fit a variety of shapes, it can be used to repair any damage to a tank, no matter the size or severity or location in the tank. From small patches to a complete rebuild and replacement of a tank, carbon fiber can be engineered to provide a solution. Carbon fiber is used in a variety of industries, including Nuclear Power and Oil & Gas due to its huge benefits when used for tank repairs. These benefits include its resistance to corrosion, its increased strength in comparison to steel, and the ease of its application in repairs. Carbon fiber also falls within several standards including the ASME PCC-2 and the ISO 24817 standards. These two standards address leak repairs and provide relevant design equations, helping companies that use composite repair solutions to ensure the products are adequately tested to provide a long-term solution. There are several standards that are relevant to the use of carbon fiber composites for repairs specifically for tanks. The ISO 24817 standard provides guidance on determining the minimum size for a carbon fiber composite patch. API Standard 653 allows for the use of composite repair patches on tank shells, in conjunction with ASME PCC-2 Article 4.1, as well as for floating tank roofs. Types of Carbon Fiber Composite Tank Repairs Spot Repair Before During After Roof Repair Before During After Tank Wall Before During After Here are several specific examples of Advanced FRP Systems work in carbon fiber composite tank repairs: Use Case/Example Methodology Benefits Spot Repairs Used on tanks that are experiencing isolated corrosion or erosion, even with through-wall failures Decontamination of microbes if necessary. Removal of corroded material. Carbon fiber composite patches to cover the damaged areas. Quick and efficient installation. Provides a high-strength, chemical-resistant barrier compatible with a wide range of high-performance coatings. Sectional Repairs Used on tanks experiencing larger scale corrosion limited to certain areas. Performed on tank floors, walls, and/or roofs. Decontamination of surface microbes. Removal of corroded material. Walls, floors, or roofs are reinforced with carbon fiber bands. Carbon fiber repair patches where applicable. Provides structural reinforcement, leak prevention and mitigation, and long term corrosion prevention. Short downtimes for complete service repairs. Full Tank Enhancement Used on tanks experiencing systemic corrosion that are still structurally sound. Decontamination of any microbes. Either interior or exterior of tank grit blasted to near white-metal finish. Weld seams and pitting covered in FRP Repair Putty Wrapped in several layers of carbon fiber and finished with a topcoat. Avoids replacing the tank. Increases the strength of the original tank. Resolves leaks in the weakest areas of the tank Structurally Independent Tank Used on tanks experiencing extreme degradation and need a complete rebuild. Using the existing tank as a mold, a composite carbon fiber tank can be built within the existing tank. A third party engineer certifies that it is structurally sound as a free-standing structure. Avoids replacing the tank Meets and/or exceeds all the original design parameters Custom Solutions with Advanced FRP Systems Carbon fiber composites have become the go-to solution for tank repairs and Advanced FRP Systems has a wide range of these types of solutions. With extensive testing in a range of chemicals and exposure conditions, you can be sure your repair will last. Call or contact Advanced FRP Systems to prevent future corrosion in your tanks, or to to discuss any necessary repairs. Depending on the type and the amount of damage to the tank, we’ll have a solution that suits your needs.
