CONCERNS – Cu-Ni Erosion Toxicity Chlorination Used for Cleaning Reduced Water Flow - Limited to Weight Cu-Ni Systems is Toxic, Forming 6–12 ft/sec Doubles (& More) for Pipe Cupric Chloride - Poisoning Port (Larger Size Pipe & Fittings for Waters (Limits the Ship’s Days in & Fittings’ Systems Cooling Water Volume) U.S. Ports & EPA Restrictions) Life-Cycle Cost Service Failures Fire Cu-Ni Requires System De-Salination Units in Mid Lower Melting Point – Replacements (Tear Down & & Far-East (High 2065 0F – 2200 0F Replacement Labor & Maintenance or Fail / Material Costs) Corrode After Few Years) Performance metal solutions. SOLUTIONS - Titanium Non-Toxic Reduced Weight Highly Resistant to Erosion I– Chlorination Has No Effect on 57% to 72% Using Reduced Water Velocity~20-100 ft/sec Titanium. No Metal Carryover. Pipe Size. Both OD & Wall Allows Reduced Pipe Sizes & Immune to Chlorides. High Velocity Factor In Weights. 50% From Reduces Weight Water Flow – Option (w/o any Density Alone (0.163 lbs/in3 vs. Erosion) 0.323 lbs/in3) Marine/Navy Titanium Tubes High Melting Point Lasts the Life of The Ship & More.
