Clad plates

Roll-bonded plates are the economical alternative to expensive high-alloy solid plates. They offer an optimum combination of mechanical properties and corrosion resistance.

Clad plates

Our roll-bonded plates and heads are used in chemical apparatus engineering and refineries, in the oil and gas industry, in oil sand processing (coke drums) and in the food industry. Clad plates are used in seawater desalination and flue gas desulfurization systems.

Materials

A roll-clad sheet or plate consists of a base and a coating layer material.

The basic materials for our clad plates come 100% from our own steel production in Linz. Cladding materials are purchased in the form of slabs and plates from renowned manufacturers.

The basic materials used are primarily structural steels, boiler and pressure vessel steels and fine-grained structural steels that are characterized by good weldability and workability.

As cladding materials, we supply ferritic and austenitic stainless steels, nickel and nickel-based alloys, copper and copper-nickel alloys that are characterized by their respective corrosion properties.

Further details can be found in the brochure linked below.

The surfaces of the base materials are usually supplied in as-rolled condition or are sandblasted.

The surface of the cladding material is usually ground. We supply ground with grain 80 as a standard. Further grindings can be supplied upon request.

Here you will find more detailed information about delivery conditions and certifications for clad plates.

Clad linepipe plates

voestalpine is the world market leader in the field of roll-bonded linepipe plates. The highest sourgas requirements are met by roll-bonded linepipe plates with corrosion-resistant cladding.

Clad linepipe plates

Sourgas resistant plates for tubes

Sourgas occurs in oil and gas production and is considered highly corrosive. Only the best materials can withstand this aggressive medium. As one of the leading suppliers of sourgas-resistant linepipe plates worldwide, we supply roll-bonded linepipe plates with corrosion-resistant cladding for this specific application.

Protective cladding

The base material is decisive in linepipe production. Our roll-clad plates exhibit high strength, good toughness and best corrosion protection as a result of the cladding material. The combination of the X65 product with nickel-based alloy 625 achieves these optimized properties in the material. Our partners process the material into metallurgically bonded linepipe.

Quality defies the elements

The metallurgical bond of the clad linepipe withstands the highest mechanical stress and dynamic loads. These pipes are ideally suited for use in deep-sea pipelines under corrosive conditions.

Reeling and riser pipes 

  • Roll clad plates for pipelines 
  • High corrosion resistance, even for the most demanding sourgas requirements 
  • Reeling of pipelines more efficient and cheaper than welding on board 
  • Roll-bonded plates for metallurgically bonded linepipe to vertical pipelines (risers) 
  • Excellent metallurgical properties of roll-bonded plates for highest compressive strength

Specializing in extreme conditions

Lowest arctic temperatures, highest pressure in the deep sea, acidic media: Even the most adverse conditions cannot harm our linepipe plates. Our plates can be found at depths of up to 3000 meters below sea level as sourgas-resistant linepipe plates or as land pipelines with a diameter of up to 48" (1220 mm). The highest sourgas requirements are met by our roll-bonded linepipe plates with corrosion-resistant cladding. As specialists in modern thermomechanical rolling processes with accelerated cooling, we are one of the world market leaders in linepipe plates. More than 2 million tons of sourgas-resistant linepipe plates and extremely tough linepipe plates for thick-walled deep-sea pipelines are ample proof of our product success.
