.prevention of corrosion
Sea water systems can be protected using some prevention measures, such as-
1. Material selection should be good.
-steel
-copper alloy
– aluminium alloy can be used.
2. Improvement (alloy) in material should be done
3. Alteration of environment can improve corrosion such as
– low temperature
– lower flow rate
– change pH – increase alkalinity
-add inhibitors
4. Cathodic protection such as
– sacrificial anode
and
– ICCP (Impressed Current Cathodic Protection) gives protection
These Can protect sea water system.
5. Coating protection
– Paint
– Metal painting
– organic coating (rubber lining)
