Turbine HP Cylinder High-Pressure Steam Inlet Pipe Flange

The High-Pressure Steam Inlet Pipe Flange is not merely a connection point; it is a critical, pressure-bearing sentinel at the heart of the steam turbine system. This flange is entrusted with the monumental task of seamlessly connecting the high-pressure steam pipeline to the turbine's HP cylinder, expertly channeling and securely sealing the superheated, high-velocity steam.

As an indispensable component, its integrity directly dictates the safety, operational stability, and overall thermodynamic efficiency of the entire turbine unit. Failure is not an option when operating under the industry's most demanding conditions, which is why our flange is engineered for uncompromising reliability.

Product Features: Unrivaled Engineering for Power Generation

• Exceptional High-Temperature and High-Pressure Resistance: Forge ahead with confidence. This flange is precision-forged from meticulously selected special alloy materials (such as specialized stainless steels or chrome-molybdenum-vanadium alloys). It is built to consistently withstand the punishing impact of high-temperature, high-pressure steam characteristic of supercritical and ultra-supercritical power generation cycles. It is designed for operational temperatures that can routinely exceed 566°C and handles design pressures meeting or exceeding 16MPa, guaranteeing resilience in the most severe environments.

• Precision Sealing Structure for Zero Leakage: Engineered to maintain the perfect seal. The design incorporates multiple, meticulously machined sealing grooves and features an optimized, mirror-finish sealing surface processing. This advanced geometry is crucial for maintaining an impeccable, leak-proof seal even when subjected to significant thermal expansion and contraction cycles during startup and shutdown. This superior sealing integrity is essential for preventing costly high-temperature steam leakage (a major safety hazard) and dramatically reducing energy and efficiency losses.

• High-Strength, Weight-Optimized Structure: Strength where it counts, without the bulk. The structural layout has been rigorously optimized using advanced Finite Element Analysis (FEA), ensuring maximum structural integrity while simultaneously achieving a reduced overall weight. This calculated optimization not only enhances manufacturability but also minimizes thermal stress concentration points, significantly improving the structure's overall fatigue resistance and extending its service life under cyclical loading.
