![]() If subsequent long stagnant conditions are expected, blow dry the systems. If polluted water has been used, it should be disposed of quickly and the pipework rinsed properly with clean sea water or fresh water. Use clean, unpolluted seawater or fresh water for hydrotesting.Avoid introduction of solid matter by installation of strainers.Clean dirt, lubricants and debris from the system.Guidelines For Good Surface Film Formation: To obtain the high performance achievable from Cu-Ni, particular attention should be given to using alloy compositions which comply to international standards, maintaining flow velocities within accepted limits, avoiding areas of local turbulence and extended exposure to polluted water and ensuring good commissioning/start up practices. Cu-Ni is used for piping systems in a wide range of sizes.
