Tenaris has supplied 780 tonnes of high strength steel grade TS890 structural tubes to Sarens, a global leader in crane rental services, heavy lifting, and engineered transport, for the design of the largest crane currently available on the market: the SGC-250. The SGC-250, characterized by a maximum load moment of 250,000 tm enabling 5,000 tonne lifts, will support the construction of the Hinkley Point C nuclear power station, the United Kingdom’s largest and most complex civil engineering project, which is responsible for supplying seven percent of the country’s low carbon electricity. For a technically demanding crane design like the SGC-250, the critical factor is controlling weight while ensuring high resistance to stress requirement.

The construction industry has been requiring more specialized cranes capable of lifting extreme weights or large components to great heights. The combination of heavy lifting and hoisting capabilities called for the crane lattice boom to be as light as possible. To achieve this goal, high strength steel pipes are used, allowing crane designers to reduce significantly the wall thickness of the originally defined pipe dimension. Tenaris has developed a complete family of modern, high-strength steel grades, ranging from TS690, TS770, T890 up to TS960, with particular attention to weldability, as well as to a clean and smooth pipe surface after undergoing quenching and tempering heat treatment.
