| Copper Alloys for Marine Environments - The aim of this publication is to provide
engineers with an appreciation of copper
alloys commonly used in marine applications. It will provide an overview of the range of alloys and their properties, and give references and sources for further information |

| Cu-Ni is used for piping systems in a wide range of sizes. 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. | |||||

| This paper discusses general guidelines that should be considered when choosing copper alloys for service in a marine environment. Topics discussed include: protective film formation, effects of velocity, seawater cavitation, effects of sulfides, marine biofouling, stress corrosion cracking, galling and sizing resistance, and use in desalination environments. | |||||

| Seawater systems are used by many industries such as shipping, offshore oil and gas production, power plants and coastal industrial plants. The main use of seawater is for cooling purposes but it is also used for fire-fighting, oil field water injection and for desalination plants. | |||||

| This paper reviews materials requirements for MSF plants and in particular the use of Cu-Ni alloys. Although heat exchanger tubing is the most important individual application, there are other important uses such as tubeplate, water boxes, piping and evaporator shells. The Cu-Nis are used for a wider range of components than any other material in MSF evaporators. The requirements of these components will be considered. Also some of the problems which have occurred in MSF plants will be described. | |||||

The Alloy
Solution to Fastener Problems in the Marine Industry
|
|||||
|
Vessels and equipment built for service in seawater and other marine environments must employ fasteners that are resistant to corrosion by the aggressive service conditions to which they are exposed. Contractors and fabricators who build ships for the U.S. Navy must recognize this requirement, as a structure is no stronger or more reliable than its weakest member. Failure of a nut or bolt can have catastrophic results. |

Experience with Copper Nickel Alloy
Tubing, Water boxes and Piping in MSF Desalination Plants. |
|||||
| The first generation MSF desalination plants were built with copper alloy tubing and either bare or coated carbon steel chambers, water boxes and piping. The intended design life was 20 years. It soon became apparent that inleakage of air into the chambers allowed more corrosion of steel than could be tolerated. Steel in these applications began to be replaced with clad or solid copper alloy, and in some plants with clad or solid stainless steel. Currently many units use copper alloy throughout, although titanium tubing is used in some heat reject sections where sulfides or special considerations are overriding considerations. | |||||
