Customized High-Strength Heat-Resistant Stud Bolts with Symmetrical Threads for Uniform Preload in Steam Turbines

These specialized stud bolts are engineered for exhaust casings and expansion joints operating under unit conditions with negative pressure heat exchange and frequent thermal displacement. Designed to withstand demanding thermal environments, they ensure reliable performance in critical steam turbine applications.

• Forged from high-strength heat-resistant materials for superior durability
• Symmetrical, well-formed threads at both ends for optimal fastening
• Sufficient shank strength providing excellent resistance to tension, deformation, and vibration
• Effectively compensates for minor equipment deformation during thermal expansion and contraction
• Maintains uniform preload to prevent flange loosening and air/gas leakage
• Ideal for long-term fastening of flexibly connected flanges
• Serves as core spare parts for steam turbine low-pressure exhaust system overhauls

Specifically designed for exhaust casings and expansion joints that generate continuous thermal expansion and contraction displacement during operation. These stud bolts provide critical fastening solutions for flexibly connected flanges in steam turbine systems.
