Clad metal plate is used in corrosion-resistant process equipment such as pressure vessels and shell-and-tube heat exchangers.
Clad metal plate is used when industrial equipment needs the mechanical strength of a structural base metal and the surface performance of a corrosion-resistant alloy. Instead of manufacturing an entire component from an expensive alloy, a thinner cladding layer is metallurgically bonded to a thicker base plate. The result is an engineered material that can balance strength, corrosion resistance, fabrication requirements and lifecycle cost.
This construction is particularly valuable in process equipment exposed to corrosive media, seawater, elevated temperatures, pressure or repeated thermal cycles. Common applications include pressure vessels, reactors, towers, shell-and-tube heat exchangers, condensers, evaporators, crystallizers, pipelines and fabricated vessel heads.
| Key takeaway: The best clad plate is not selected by industry name alone. Service medium, temperature, pressure, plate dimensions, fabrication route and inspection requirements determine the appropriate material combination and bonding method. |
A clad metal plate contains two or more metal layers joined into one composite plate. The base layer - commonly carbon steel, stainless steel or alloy steel - provides structural capacity. The cladding layer supplies the surface property required by the application, such as corrosion resistance, heat resistance or electrical and thermal conductivity.
FUGO supplies clad plates with stainless steel, duplex steel, titanium, nickel alloy, copper alloy, zirconium and tantalum cladding options. The layers may be joined by explosion welding, roll bonding or an explosion-plus-rolling route, depending on the material combination and project specification.
Corrosion protection. The cladding layer is selected to contact the process medium, helping protect the structural base from chemical attack, seawater or other corrosive environments.
Structural efficiency. The base plate carries mechanical loads, allowing the corrosion-resistant alloy to be concentrated at the working surface where it is needed.
Material flexibility. Different cladding alloys can be paired with steel to address process conditions, fabrication needs and applicable standards.
Fabrication potential. Qualified clad plate can be cut and processed into equipment components such as shells, tube sheets and formed heads, subject to the approved fabrication procedure.
Chemical processing equipment often combines pressure and temperature with aggressive media. Clad plate is used for reactor shells, pressure vessels, columns, towers, storage equipment, crystallizers and evaporators. Stainless steel, duplex steel, nickel alloy or titanium cladding can provide the process-facing surface, while the steel base supplies structural strength.
Shell-and-tube heat exchangers are another important application. Clad plate may be specified for shells, channel covers and tube sheets when the equipment must separate corrosive process fluids from cooling or heating media.
Oil and gas facilities use clad plate in pressure vessels, separators, reactors, columns, heat exchangers and corrosion-resistant piping components. Offshore and coastal projects may also require materials that tolerate marine exposure and demanding maintenance conditions. Selecting the cladding alloy requires a clear definition of the process medium, operating conditions and fabrication route.
For EPC and equipment projects, clad plate can reduce the amount of high-alloy material in large components while retaining a corrosion-resistant internal surface. This makes it relevant to refinery, LNG, gas-processing and offshore equipment where reliability and inspection documentation are central to procurement.
Power-generation systems use clad materials in heat exchangers, condensers, pressure-containing equipment and other components exposed to hot, pressurized or corrosive service. Titanium- or stainless-steel-clad solutions may be considered for condenser and cooling-water applications, while nickel-alloy cladding may be evaluated for more demanding chemical and temperature conditions.
Desalination, wastewater treatment, evaporation and salt-extraction systems expose equipment to chlorides and concentrated process streams. Clad plate can be used in evaporators, condensers, tanks, pressure vessels and heat-transfer equipment. FUGO project references include titanium-clad materials used for environmental evaporation and salt-extraction equipment.
Marine equipment must address seawater exposure, structural loads and long service intervals. Clad plate can be evaluated for tanks, process modules, heat exchangers, piping components and specialized marine structures. The material combination should be selected with attention to seawater chemistry, joining procedures and inspection access.
Copper-steel clad plate combines the structural function of steel with the conductivity of copper or copper alloys. FUGO lists electrode arms among its supplied clad-plate applications. Metallurgical and process plants also use clad materials in equipment where corrosion resistance, conductivity or a specialized working surface is required.

Clad plate manufacturing and inspection require controlled fabrication, dimensional checks and bond-quality testing.

FUGO manufactures clad plate using explosion welding and roll bonding. Explosion welding versus roll bonding should be assessed according to material compatibility, plate thickness, dimensions, production quantity, flatness and downstream fabrication.
Explosion welding. Often selected for thick plates, customized sizes, special geometries and dissimilar-metal combinations that are difficult to join through conventional routes.
Roll bonding. Often selected when consistent thickness, surface flatness, repeatability and efficient production are important.
Combined processing. An explosion-bonded plate may undergo heat treatment, rolling or flattening to achieve the required dimensions and mechanical condition.
FUGO supplies stainless-steel-, titanium-, nickel-alloy- and copper-alloy-clad plate for process equipment and custom fabricated components. The team can review the material combination, bonding route, dimensions, inspection plan and downstream processing requirements for your project.
