  • 10. Customized Solutions Fast, Easy Installation Superior Operating LifeISO 9001:2008 Certified Key Design Considerations for Reinforcement Layer  Long Term Static Design Strength  Cyclic Loading Strength  Chemical Compatibility
  • 11. Customized Solutions Fast, Easy Installation Superior Operating LifeISO 9001:2008 Certified Long Term Static Design Strength  Long Term Testing Per ASTM D2992 – Slope of Line is a Function of Reinforcement material – Basis for all RTP’s
  • 12. Customized Solutions Fast, Easy Installation Superior Operating LifeISO 9001:2008 Certified Impact of Cyclic Loading Utilizing Aramid Fibers  275PSI Rated Pipe  300PSI Pressure Cycle Amplitude  100,000cycles (20 year Design Cycles for APP)  1 Cycle Per 2 Seconds  No Change in Unreinforced Product Sample Number Burst Pressure (PSI) Sample 1 1,885 Sample 2 2,016 Sample 3 1,958 Baseline 1,984 Sample Average 1953.3 Standard Deviation 65.6
  • 13. Customized Solutions Fast, Easy Installation Superior Operating LifeISO 9001:2008 Certified Impact of High Temperature and Acidic Environment on Aramid Fibers  All Aramids are not the Same  Assume the Outer Jacket of RTP will be Breached  Test for Temperature and Environment
  • 14. Customized Solutions Fast, Easy Installation Superior Operating LifeISO 9001:2008 Certified Key Considerations for Outer Jacket  Abrasion Resistance  Compatibility with Outside Environment  Toughness – Cold Temperature – Rapid Impact
