Designed Solutions Ultra-Build Epoxy Lining Systems Description Product Lines Through more than 16 years of testing and applying epoxies in various applications, Citadel Technologies engineering SLS-30™ Structural Liner. team has developed a broad range of epoxy systems that can be tailored to your specific needs. SLS-35™ Super Fast Patching Compound. All of your epoxies are easy to apply, are great for long-term durability, and contain no VOC´s. SLS-60™ Strong Acid Liner. SLS-70™ High Temp Liner. Our most popular products are the SLS-30™, SLS-300™, and SLS-350™ products: SLS-300™ Solid Epoxy Coating. SLS-30™ is a two component, 100% solids epoxy system. It provides both a structural, cured-in-place lining and SLS-350™ Solid Epoxy Coating. a chemical protective barrier in one quick application. It is commonly used in waste collection systems, sewers, lift stations, tanks, vaults and cooling lines. SLS-300™ is a one step, low cost flexible sealant with excellent bonding properties that can be applied to dam or wet substrates. It is commonly used for manhole rehabilitation, catch based grade rings and joints, but it is also used in a variety of situations where shifts and movements may occur. SLS-350™ is a two component, 100% solids epoxy system. It provides both a structural, cured-in-place lining and a chemical protective barrier in one quick application. It is commonly used in waste collection systems, sewers, lift stations, tanks, vaults and cooling lines. Slower setting and longer pot life than SLS-30™, can be used where spray application is not viable. SLS-Series™ are approved by L.A. County, and City of Los Angeles. 17 18

Cathodic disbondment tests were conducted on Appendix III. The results are shown for repairs with a maximum of 6 layers of carbon on the repair, when the pipe was A-106, Grade B steel pipes on which carbon- fiber-reinforced polymeric wraps were installed. The composite wraps repaired with no internal pressure applied. Both defects were 6 inches long, and the patch defect was 6”x6”in area. are part of system used to repair externally damaged or corroded steel pipes. To stimulate a corrosive environment, pipes coated with the composite wraps were submerged in an electrolyte consisting of potable water, sodium chloride, Failure Pressure sodium sulfate and sodium carbonate.

The carbon /epoxy systems is intended to repair externally load during its lifetime. damaged or corroded steel pipe. Six-inch nominal diameters by five feet long pressure vessels were constructed from A-106. Grade B steel for test purposes. Defects were machined into the outer surface of each pressure vessel to determine limitations of the carbon /epoxy repair system. Unrepaired pipes were cycled to determine a base number of maximum operating cycles. Remaining vessel were wrapped and then cyclically pressurized until a leak in the system was detected. The repaired vessels were compared to un-repaired vessels with equal size defects to determine the effectiveness of the repair. Results indicate there was a substantial increase in the performance of the pipe.

  13. 13. Test Information Chemical Resistance Dents Tests involving dents and gouges were performed both by the University of Tulsa and by Stress Engineering. The results Chemical Resistance for Standard Epoxies of this test program, along with supporting data from other studies on these repair systems, confirm the validity of 30 Days Exposed this repair system for repair of dents and pipes with gouges. The reinforcement provided by the carbon fiber/epoxy Water No effect composite repair system provides a significant increase to the fatigue life of un-repaired mechanically damaged pipes. Sulfuric Acid,20% No effect Sodium Hydroxide,50% No effect Composite Repairs Made Under Load Ammonium Hydroxide,5% No effect Testing was conducted on Citadel Technologies’carbon composite products by wrapping defective pipe while under Nitric Acid,1% No effect internal pressure loading. Test pipes with flaws varying form 20% to 75% wall loss were wrapped while the pipe was Sodium Hypochlorite(Bleach) No effect operating at MAOP. The pipes were then cycled between 50 psi and MAOP. After inspection indicated that there was no Ferric Chloride,1% No effect de-lamination, the pipes were pressured to rupture. No differences were noted to those pipes that were wrapped at zero Detergent Solution No effect pressure. This testing shows that defects may be repaired without reducing the pipeline pressure prior to wrapping. Gasoline No effect Tolune No effect Citadel Technologies’ standard epoxy is designed for operating temperatures up to 180°F.

  15. 15. APPENDIX FORMS Product Care Engineering Assessment Storage and Shelf Life Citadel Technologies´ epoxies products have a minimum shelf life of two (2) years when stored in a dry place at room temperature and sealed in the original unopened container. CN#_________ Optimum Handling Characteristics ENGINEERING ASSESSMENT Can be achieved by heating the epoxy systems to temperature range of 20°C –30°C (68°F - 86°F). Citadel Technologies´ epoxy products come pre-measured for application. Products consist of “Wetouts” and “Hardeners.” Low pressure High Pressure Some are self-activating when mixed or in the case of high temperature products activated by elevated temperatures. All materials for pipe sizes identified are pre-cut and pre-measured at our manufacturing facility to meet strict Please FAX information (918.584.2221) requested regarding the Diamond Wrap application under consideration.
