Hard shell - stainless core Clad Pipes EEW Group Products Line & Process Pipes Clad Pipes Complex process of metal bonding Cladding refers to a process in which a metal, CRA or composite (the cladding material) is mechanically or metallurgically bonded to another dissimilar metal (the backing material) to increase its resistance (e.g. to corrosion) on the one hand and its strength on the other. The majority of clad products manufactured today combines carbon steel for the backing material and e.g. aluminum, nickel, nickel alloys, copper, copper alloys or stainless steel for the cladding material to be bonded. Typically, the purpose of the clad is to protect the underlying steel material from the transported medium. The cost of using clad pipes in pipeline projects is therefore only a fraction of the cost of what it would cost to use a more expensive solid steel alloy for the entire product. 12 - 96 inch outer Diameter 0.375 inch min.

Engineers act on the assumption than corrosion contributesto more than 50% of offshore pipeline failures. This is because the internal reservoir fluids and gases do significantly increase the corrosion of a conventional pipeline. The ingredients of these gases and fluids are typically aggressive elements such as chlorides, sand, organic acids, carbon dioxides (sweet crude) and hydrogen sulfides (sour crude). While CRA are commonly used to combat corrosion of pipes in sweet and sour crude mediums, nickel based alloys are rather used for resistance to ultra-sour fluids and gases. In addition, the high temperatures and pressures encountered in the subsea well can lead to corrosion in pipelines and risers which are unavoidable to get oil and gas products to the consumers. Combination of Corrosion Resistance and Toughness Environmental conditions such as corrosive medium, growing safety requirements and project cost pressure have changed the dynamics and demands in the pipeline industry. Clad materials combine the corrosive and/or wear resistance properties of corrosion resistant alloys (CRA) respectively high-alloyed materials with the high strength and toughness of carbon manganese steels. This combination results in potential reductions of the total wall thicknesses as well as a minimized need for CRA material both leading to significant cost savings of up to 70% or more, depending upon steel grade and wall thickness.
