| High Light | SA213 T91 Membrane Wall Panel ，φ60×6mm 9Cr-1Mo-V Tube ，Supercritical Furnace Enclosure | ||
The SA213 T91 High Pressure Boiler Membrane Wall Panel represents the pinnacle of boiler membrane wall technology. Manufactured with φ60×6mm modified 9Cr-1Mo-V (Grade 91) alloy steel tubes, this panel is engineered for ultra-supercritical (USC) boiler furnace enclosures operating at the highest temperature and pressure regimes in the power generation industry.
Constructed from SA213 T91 (ASME Grade 91) seamless tubes, a martensitic 9% Chromium steel enhanced with Molybdenum, Vanadium, Niobium, and controlled Nitrogen additions. This advanced alloy delivers the highest creep rupture strength in the 9Cr steel family, enabling thinner wall designs that improve heat transfer while reducing overall panel weight. Membrane bars are fabricated from SA387 Gr.91 plate material with identical chemistry for perfect metallurgical compatibility.
Strict PWHT (Post-Weld Heat Treatment) protocol at 730-760°C per ASME B31.1 and ASME Section I requirements. Hardness testing on all welds to verify tempering (max 250 HB). Full PMI, UT, RT, and hydrostatic testing. All documentation compliant with EN 10204 3.2 certification upon request.
