Metallurgically bonded clad pipes are made of roll-bonded clad plates. These clad pipes provide the high strength and good toughness of the base material as well as the proper corrosion resistance of the clad material. A typical material combination is a pipe grade like X65 and a nickel-based alloy like Alloy 625.

The metallurgical bond of the clad pipes is most efficient for highest mechanical demands and even can bear dynamic loads. Thus these clad pipes are highly useful in deepwater linepipes under corrosive conditions as well as for bends and fittings.

Our roll-bonded clad plates offer the characteristics that allow the pipelines to be rolled and unrolled and they have the corrosion resistance needed in deep-sea environments. The reeling of pipelines is much faster – and thus cheaper – than welding pipes onboard.

Another application of metallurgically bonded clad pipes made of roll-bonded clad plates are so-called catenary risers in the offshore industry. These vertical pipelines connect the subsea gas or oil field with the production facilities above sea level. Due to the high pressure of deep water installations and dynamic loads by waves and drifts as well as due to the corrosive medium inside such riser pipes must provide excellent mechanical properties as high strength combined with good toughness as well as proper corrosion protection.
