SA210 Gr.C Carbon Steel Boiler Membrane Wall Panel with φ51×5mm Seamless Tube and High-Frequency Resistance Welding for HRSG Water Wall Section

The SA210 Gr.C Carbon Steel Boiler Membrane Wall Panel with φ51×5mm seamless tubes is engineered for heat recovery steam generator (HRSG) water wall sections in combined cycle power plants. This heavy-duty panel delivers reliable performance under cyclic thermal loading conditions.

Fabricated from SA210 Gr.C medium carbon steel seamless boiler tubes, offering higher tensile strength compared to Gr.A1. The tubes are welded to Q245R carbon steel membrane bars using precision high-frequency resistance welding (HFRW), creating a continuous gas-tight membrane structure. SA210 Gr.C provides excellent creep resistance at elevated temperatures up to 450°C.

• Enhanced Strength: SA210 Gr.C material provides superior yield and tensile strength for high-pressure applications
• HRSG Optimized: Designed to withstand thermal cycling typical of combined cycle plant start-stop operations
• Leak-Proof Welding: 100% HFRW with automated weld monitoring ensures consistent membrane bond integrity
• Modular Design: Pre-fabricated panel sections reduce on-site welding and installation time by up to 40%
• Full Traceability: Each tube is marked and traceable to its original heat number and material test certificate

All panels undergo hydrostatic testing, radiographic examination of tube butt welds, and dimensional inspection per ASME Section I requirements. Material certificates per EN 10204 3.1 are provided with each shipment.

Specifically designed for HRSG evaporator water wall sections in combined cycle gas turbine (CCGT) plants, cogeneration facilities, and industrial waste heat recovery systems. Custom configurations available for replacement and new-build projects.
