Customized High-Strength Alloy Steel Groove Nuts with Precision Tooth Profile for Steam Turbine High Temperature Resistance

Customized groove nuts are specially engineered fasteners designed for the horizontal joint of steam turbine cylinders. These critical components serve as key fasteners for turbine cylinder split faces, manufactured to precise custom drawings and specifications to match various steam turbine models.

• Constructed from high-strength alloy steel material
• Precise tooth profile and groove machining
• Excellent mechanical strength and durability
• High temperature resistance and creep resistance
• Designed for harsh working conditions of high temperature and high pressure

When installed on the cylinder horizontal joint, the specialized groove structure ensures reliable positioning and uniform pre-tightening force distribution. This design effectively prevents nut loosening under thermal cycling and vibration conditions, maintaining optimal sealing performance of the cylinder split surface and preventing steam leakage.

Our customized groove nuts are widely used in steam turbine overhaul projects, maintenance operations, and new unit assembly installations across various industrial applications.
