steel, tubular, pipes, nanotechnology
While traditional tubular steel tubular goods manufacturing and finishing technologies are getting closer to their limits, nanotechnology offers unique opportunities to achieve these new demands. It is in the field of coatings and nanostructured surfaces where nanotechnology can make its greatest contribution to this industry but also nanotechnology solutions are being pursued for “greener” and enhanced steel pipes manufacturing processes. Among other applications, nanotechnology research for steel tubular goods in Tenaris is focused in coatings or modified surfaces for improved fluids flow (gas, water, oil ), higher wear and corrosion resistance, enhanced tribological properties in threaded connections, better thermal insulation for Line Pipes, chromium replacement in tooling and accessories , etc. The challenge for nanotechnology in this industry is huge since the requirements for robustness and durability in harsh environments are serious limitations for nano-engineered solutions that in other areas have found a relatively smooth implementation.
