Product Introduction
The Steam Turbine Shaft from our company represents the state of the Art of the engineering science. This main rotating part is made of the first-class alloy steel, and after the hot forging we apply the necessary accurate heat treatment, as well as the modern manufacturing to get the desired shape.
To ensure maximum reliability along with the good balance of the dynamic forces, the shaft has been developed in such a way that it can survive under the conditions like high temperature, pressure, and large amounts of the rotational loads.As the central part of the turbine the steam turbine shaft can be broadly used in the fossil fuel, nuclear and the large thermal power generation plants so the steam turbine unit is able to work without fail and for a long time.
The material used for the production is 28CrNiMoV49 and can be customized as customer's requirements.
HHF is a national high-tech enterprise. There are four production branches for forging, heat treatment, petroleum equipment, and mechanical processing, a provincial oil drilling tool stabilizer engineering technology research center, a physical and chemical laboratory, and a municipal technology research center.
HHF is specialized in Research,Production,Sales and Services for Petroleum and Large Precision Forging.HHF is the largest and most professional Drill Stabilizer manufacturers in China. The products such as Drill Stabilizer,Non-magnetic Drill Stabilizer,Drill Collar,Non-Magnetic Drill Collar,Drill Pipe,Mining Drill Pipe,Roller Reamer,Pump Block,Marine Shaft,S team Turbine Shaft,Motor Shaft and Pipe Mold are widely welcomed by more than twenty countries and regions as following:United States, Canada,Australia, Austria, France, Italy, Russia, Middle East, South Africa,Brazil and Singapore etc. HHF is highly trusted and acclaimed because of its Reasonable Price,Excellent Quality,Good Reputation and Perfect After-Sale Service.
