Company > HistoryThe Company > HistoryThe Company

Walter Tosto Spa is a worldwide leader for the produc-tion of heavy wall static and heat transfer equipment for Oil&Gas, Petrochemical, Power and Energy markets. Founded in 1960 by Mr. Walter Tosto, the company is man-aged by Walter Tosto’s son, MD - Luca, who widened the business to the overseas areas. Today our company operates in international markets, be-ing characterized and supported by advanced manufactur-ing technologies, more than 500 qualified employees and 9 relevant facilities: seven in Chieti Scalo, one in Romania (WTB), and one placed in the Ortona Port, on the Adriatic Sea, directly connected to main international ports and routes. Our position in the worldwide scenery has also been streghtened by an advanced, ongoing investments plan, thanks to which 60 million euros have been invested in R&D, logistics and new capabilities over the last 5 years. In particular, within the second quarter of 2010 one of our highest technological achievements was reached, since a new bending machine completed (the biggest in the world), capable of cold rolling plates up to 300 mm in thickness, completely engineered and assembled by our internal staff. Another important step in the company’s history is the acquisition of Bosco Industrie Meccaniche in 2003, that has improved Walter Tosto skills in the pro-

All above investments and plans are completely in line with the com-pany strategy to be mainly focused on the critical and very long lead items such as reactors, heavy wall pressure ves-sels and high pressure heat exchangers, in order to proceed with being considered as customers’ point of reference for the development of many important international projects. In this way, our company aims at gaining customers’ confi-dence and developing large international projects.

Engineering& Materials

Walter Tosto develops contracts specification in full compliance with Design Codes and custom-er’s requirements. More than 20 skilled engineers, draftsmen and design managers are able to satisfy contracts requirements through the application of ad-vanced software both for thermal and mechanical de-sign (ASPENTECH/HTFS/TASC+, SANT’AMBROGIO, ANSYS, AUTOCAD, SOLID EDGE etc). The full knowl-edge and familiarity with all the exsisting Design Codes as ASME, PD 5500, CODAP, STOOMWELZEN, AD 2000-Merkblattand GOST, allow Walter Tosto peo-ple to perform the most sophisticated mechanical designs according to the most advanced technical requirements. Furthermore the in-house presence of FEM experts together with the several ANSYS licenc-es, make the Finite Element Analisys a powerful in-strument in our hands, for the design of critical parts of the equipment like the forged connection between shell, head and skirt or the thin tubesheet of a Waste Heat Boiler, even 3-dimensional complete FEA mod-els have been developed in-house for particular criti-cal applications. Beside the Mechanical Design, Wal-ter Tosto has strong skillness to develop the Thermal and Fluid dynamic design of Heat Exchanger giving to our Clients all the required guarantees.

Incoming projects > ITER

Nuclear reactor ITER project

ITER is the most advanced fusion projects ever done worldwide thanks to the support and financing of the EU, Russia, India, China, South Korea and USA. ITER is based on the ‘tokamak’ concept of magnetic con-finement, in which the plasma is contained in a doughnut-shaped vacu-um vessel. The fuel - a mixture of Deuterium and Tritium, two isotopes of Hydrogen - is heated to temperatures in excess of 150 million°C, forming a hot plasma. Strong magnetic fields are used to keep the plasma away from the walls; these are produced by superconducting coils surround-ing the vessel, and by an electrical current driven through the plasma. The Vacuum Vessel is a hermetically-sealed steel container inside the Cryostat that houses the fusion reaction and acts as a first safety con-tainment barrier. In its doughnut-shaped chamber, or torus, the plasma particles spiral around continuously without touching the walls. The size of the Vacuum Vessel dictates the volume of the fusion plasma; the larger the vessel, the greater the amount of power that can be pro-duced. The ITER Vacuum Vessel will be twice as large and sixteen times as heavy as any previous tokamak, with an internal diameter of 6 metres. It will measure a little over 19 metres across by 11 metres high, and weigh in excess of 5.000 tons. The Vacuum Vessel will have double steel walls, with passages for Cool-ing Water to circulate between them. The inner surfaces of the Vessel will be covered with Blanket Modules that will provide shielding from the high-energy neutrons produced by the fusion reactions. Some of the Blanket Modules will also be used at later stages to test materials for Tritium Breeding concepts.Forty-four ports will provide access to the Vacuum Vessel for Remote Handling operations, Diagnostic systems, Heating, and Vacuumsystems: 18 upper ports, 17 equatorial ports, and 9 lower ports.

Incoming projects and investments

“To look ahead” is Walter Tosto’s leitmotiv: inno-vation and new challenges characterize the company.

In 2010 WT started facing the nuclear market, signing a contract, in consortium with Ansaldo Nucleare and Mangiarotti, for the supply of the Vacuum Vessel of the fusion reactor of the ITER project.

Thanks to this experience, the company will shortly further improve knowledge, processes and quality of the performance in all the markets.

a new workshop for special process and sophisticated mechanical machining

Furthermore, Walter Tosto started and successfully concluded at the end of 2011 the procedure for the certification Stamp N and NPT.
