Clad pipes performances

Today, great efforts are made by the pipeline industry to satisfy the need to transport gas from distant regions to the final market and to find new solutions in terms of both design criteria and new high performance materials. Material resistance requirements are growing due to the fact that the new fields are increasingly likely to be located in deep and ultra-deep water, where pressures and temperatures are higher and the environments are more corrosive.

In this situation, low-alloy carbon steels tend to be structurally adequate, but they lack corrosion resistance. On the other hand, stainless steels and nickel alloys resist corrosion environments, but they lack strength and their cost is excessively high. Consequently, pipes, bends and fittings made from metallurgically-bonded clad plates are both a good technical and economic choice for the transport of oil&gas.

Nowadays clad materials, i.e. low-alloy carbon steels with a thin layer of a Corrosion Resistant Alloy (CRA), are increasingly considered to be a suitable solution to the most demanding requirements for strength, corrosion resistance and cost-effectiveness arising from flowlines designed to carry wet, corrosive oil&gas production streams with high pressures and temperatures.

In a clad pipe or fitting, the unalloyed carbon steel sustains the internal and external pressure, while the high-alloy cladding provides the corrosion protection.

Gieminox Tectubi Raccordi is perfectly able to provide the oil&gas market with any kind of clad products and to plan implementation also for power generation with a flexible technological solution, the full range of products and related technological services.
