Gas turbines - Import export

Standard : EN 10028-2 / EN 10028-3 / EN 10028-4 / EN 10028-5 ASTM/ASME Our carbon and alloy steels are especially designed to produce large high-pressure vessels. These steel grades are characterized by yield strengths from minimum 235 N/mm² to maximum 460 N/mm² and by good weldability. The fine-grain structural steel grades are suitable for mechanical forming and excellent welding. We deliver these steels as heavy plates or bars, as well hot rolled and forged, so we can cover a wide range of thicknesses and widths. Our specialists can coordinate for you the steel preparation at all stages, to enable you to get your pieces ready to use. Applications : •storage tanks, storage spheres •pressure vessels •boilers •heat exchangers •gas turbines •etc…

Hamon Research-Cottrell provides process and equipment expertise, drawn from more than fifteen years of experience with the patented Urea to Ammonia U2A® technology, starting from bench and pilot scale, through systems for small gas turbine SCR and the largest utility scale SCR systems for coal and gas fired boilers.Hamon Research-Cottrell’s U2A® system provides several benefits:Urea as feedstock eliminates the hazards associated with the transport, transfer and storage of toxic anhydrous or aqueous ammonia.Compared with using 19% aqueous ammonia, energy use is reduced.Process control response provides ammonia on demand, easily following load conditions.Hamon Research-Cottrell offers U2A® on a worldwide basis and has installations in Europe and the Middle East in addition to a large installed base in the United States.
