95/5 Cupro Nickel Pipes are premium copper-nickel alloy pipes engineered for excellent corrosion resistance, durability, and reliable performance in marine and industrial environments. They offer good strength, excellent thermal conductivity, and resistance to seawater corrosion, making them ideal for condensers, heat exchangers, marine piping, desalination plants, and cooling water systems.
Excellent hot and cold workability; good forge ability. Fabricated by bending, coining, coppersmith, drawing and upsetting, hot forging and pressing, knurling, roll threading, shearing, spinning, swaging, and stamping.
Good to excellent. Susceptible to galvanic corrosion when coupled with iron, aluminum, magnesium, leads, tin, and zinc. Good resistance to atmospheric, brackish water, sea water, and non-oxidizing acid corrosion, but avoid heating in oxidizing atmospheres or exposing to oxidizing acids, moist halogens, sulfides, ammonia, or solutions with ammonium ions.
Typical Applications:
Industrial: Condensers ,Condenser Plates, Evaporator Tubes , Ferrules , Heat Exchanger Tubes, Corrosion Resistanc Corrosion Resistanc, Petrochemicals, Salt Water, Erosion and Impingement, Moderate Strength, Retains Strength at High Temperatures
Marine: Condenser Intake Systems , Salt Water Piping
