SA210 Gr.A1 Carbon Steel Boiler Membrane Wall Panel with φ38×4mm Tube and ASME Standard Compliance

The SA210 Gr.A1 Carbon Steel Boiler Membrane Wall Panel is a critical pressure part designed for industrial boilers and heat recovery steam generators (HRSG). Constructed with φ38×4mm seamless carbon steel tubes welded to continuous membrane bars, this panel forms a gas-tight enclosure that ensures optimal heat transfer and combustion efficiency.

Manufactured from SA210 Gr.A1 carbon steel tubes per ASME Section II specifications, with Q235B carbon steel membrane bars. The tubes and fins are joined using high-frequency resistance welding (HFRW), creating a homogeneous, leak-proof bond that withstands high-temperature flue gas environments. Each panel undergoes 100% non-destructive testing including radiographic and ultrasonic inspection.

• Gas-Tight Construction: Continuous membrane bar welding eliminates gas leakage, improving boiler efficiency
• ASME Standard Compliance: Manufactured to ASME Boiler & Pressure Vessel Code Section I and Section II
• Superior Heat Transfer: Optimized tube pitch design maximizes radiant heat absorption from the furnace zone
• Pre-Assembled Panels: Factory-welded into modular sections for faster on-site installation
• Corrosion Resistance: Shot-blasted and primed surface treatment protects against atmospheric corrosion during storage and transport

Every membrane wall panel is hydrostatically tested at 1.5x design pressure. Material certificates, test reports, and full traceability documentation are provided with each shipment. Our ISO 9001:2015 certified facility ensures consistent quality across all production batches.

Ideal for coal-fired utility boilers, biomass boilers, waste heat recovery steam generators (HRSG), and industrial process steam boilers. Custom panel dimensions and tube configurations available upon request.
