Corrosion in firewater and deluge systems has been proven to reduce by use of exotic materials and/or flushing with potable water after testing.

However, use of exotic materials such as Copper nickel or Titanium introduces challenges with fatigue and mechanical strength.

Movement between pre-assembled units can cause fatigue if not allowed for, and small pipe connections should be well supported. Such pipework should also be protected from damage from swingling loads…
