Cladded metals are increasingly being used across a wide range of industries, including oil and gas production, power generation plants, chemical, and even marine ship manufacturing. Cladded metals are mainly used to increase the cost-effectiveness of metal structures while preserving or increasing safety and durability.
Two or more metals can be used in layers, and they usually complement each other. For example, one layer of metal might provide corrosion resistance, while the other maintains the required structural strength. This type of cladded metal combination is common in the offshore oil industry. Here, thin layers of Inconel® or super duplex alloy can be used in conjunction with carbon steel or stainless steel alloys. In other cases, the use of stainless steel layers on carbon steel structures is a compromise between increasing corrosion resistance and keeping cost at reasonable levels.
Possible metal combinations include titanium/carbon steel, titanium/stainless steel, aluminum bronze/carbon steel, stainless steel/carbon steel, nickel alloys/carbon steel, duplex or super duplex/carbon steel, aluminum/carbon steel, etc. The types of structures that can benefit from metal cladding include tube sheets, reactor vessels, heat exchangers, condensers, and more.
