Steam Turbine Spare Parts

Steam turbine generator sets, as core power equipment in industries such as power generation, chemicals, and energy, rely on operational stability and reliability to ensure production continuity and output efficiency. High-quality spare parts are fundamental to equipment maintenance, overhaul, and upgrades. As a specialized manufacturer focused on spare parts for steam turbine generator sets, we have deep industry experience and offer integrated services covering turbine disassembly, maintenance, and manufacturing. Our core product range includes a full series of components such as turbine bolts, nuts, gaskets, valve stems, valve sleeves, valve discs, valve seats, bearing bushes, sealing rings, oil rings, gland rings, and spring plates, providing comprehensive compatibility and support for various types of steam turbine generator sets.

Fastening and sealing spare parts form the foundation for the safe operation of steam turbines, directly impacting equipment sealing integrity and structural stability. Turbine bolts and nuts are precision-manufactured from high-strength materials, offering excellent compression resistance, fatigue resistance, and high-temperature performance. They maintain tight fastening under high-temperature and high-pressure operating conditions, preventing loosening and leakage caused by vibration or thermal differentials, thereby ensuring structural integrity. Gaskets and sealing rings focus on sealing protection: gaskets are suitable for various component connection gaps with superior sealing performance, effectively preventing medium leakage; sealing rings are specially designed for turbine shaft sealing, with an optimized structure that reduces lubricant leakage and steam loss, balancing sealing effectiveness with operational efficiency.

Valve spare parts are core components for regulating flow and pressure in steam turbines, determining the accuracy of operational parameters. Valve stems, sleeves, discs, and seats form a complete valve control system. Valve stems ensure smooth transmission with wear and corrosion resistance, enabling precise valve opening, closing, and adjustment. Valve sleeves and discs are precision-matched to accurately control sealing clearances, effectively preventing medium backflow and maintaining stable pressure. Valve seats undergo specialized hardening treatment, offering exceptional wear resistance and sealing performance suitable for frequent cycling, extending overall valve service life and ensuring stable operation according to set parameters.

Shaft and protection spare parts provide support and protection for turbine rotor operation, balancing stability and safety. Bearing bushes, as core supporting components, offer excellent lubrication and load-bearing capacity, reducing friction and wear during rotor operation while providing cushioning and vibration damping to prevent component damage under heavy loads and high-speed conditions. Oil rings are responsible for circulating and evenly distributing lubricating oil, ensuring continuous lubrication for bearing bushes and rotor contact surfaces to maintain smooth operation of transmission parts. Gland rings are installed in gaps between rotors and stationary parts, effectively reducing steam leakage, minimizing energy loss, and improving unit thermal efficiency. Spring plates are designed for internal elastic adjustment in turbines, providing stable elastic reset performance to ensure coordinated operation of related components.

Leveraging our integrated capabilities in turbine disassembly, maintenance, and manufacturing, our spare parts are not only strictly quality-controlled but also highly adaptable to operational conditions. All components are precision-manufactured according to original equipment technical standards and operational requirements, undergoing multiple quality inspection stages to ensure dimensional accuracy and performance parameters are fully compatible with various steam turbine generator sets. This enables quick disassembly and replacement, significantly reducing equipment downtime for maintenance. Additionally, drawing on extensive disassembly and maintenance experience, we provide customers with full-process services including spare part selection, installation guidance, and fault diagnosis. This seamless integration of parts supply and maintenance services helps customers reduce operational costs and ensures the long-term efficient and stable operation of their steam turbine generator sets.
