Introduction of wind turbine forgings

Rich Manufacturing Experiences in the Industry


Wind turbine ring forging is an important part of the wind turbine system. We provide products such as tower connecting flanges, overall forged door frames, wind power yaw and pitch bearing and gearing forgings; wind power gearbox forgings, leaf blade flanges, wind power generator stator and rotor forgings and offshore platform forgings( monopiles, jackets) and other products. IRAETA has rich manufacturing experience in this field. Our tower flanges are used in more than 1/3rd of wind turbines in the Chinese market1, and the proportion is even higher in offshore wind power, where it accounts for more than 50%. We are a certified supplier of Vestas, Siemens Gamesa and GE, and have sold our products globally. With respect to large megawatt wind turbines, we have successively provided customers with multiple sets of 10MW+ tower flanges such as DEC 10MW, Mingyang 10MW, CSSC 10MW, GE12MW, Siemens Gamesa 11/14MW, Vestas 10MW and so on. And we also have participated in compiling the "Ring Type Forgings of Wind Turbine Generator System" standards developed by National Energy Administration, and the "Precision Forming Technology and Equipment for Wind Turbine Ring Forgings" is listed in China's Torch Plan.
