Product Description
The SA213 T22 Alloy Steel Boiler Membrane Wall Panel features heavy-wall φ51×6mm tubes in 2.25Cr-1Mo alloy steel, purpose-built for the extreme thermal and pressure conditions of supercritical and ultra-supercritical power plant furnace walls. This premium-grade panel delivers unmatched creep strength and hydrogen attack resistance.
Fabricated from SA213 T22 seamless alloy steel tubes containing 2.25% Chromium and 1% Molybdenum. This higher chromium content significantly enhances oxidation resistance, making T22 the material of choice for high-temperature furnace wall applications. Membrane bars are produced from 12Cr1MoV alloy steel for optimal weld compatibility. All panel-to-panel joints are prepared with pre-machined weld bevels for rapid field assembly.
- Premium Creep Strength: 2.25Cr-1Mo composition delivers exceptional creep rupture strength at temperatures up to 600°C, critical for supercritical boiler furnace walls
- Hydrogen Attack Resistance: Higher chromium content provides superior resistance to high-temperature hydrogen attack (HTHA) per API RP 941 Nelson curves
- Heavy Wall Design: φ51×6mm tube dimensions provide extended service life with built-in corrosion allowance for demanding coal-fired environments
- Thermal Fatigue Resistant: Alloy composition minimizes thermal expansion stresses during boiler startup and shutdown cycles
- Precision Manufacturing: CNC tube bending and laser-aligned welding fixtures ensure dimensional accuracy within ±2mm across full panel length
Positive Material Identification (PMI) on 100% of alloy components. Ultrasonic and radiographic inspection of all pressure-retaining welds. Hydrostatic testing, dimensional verification, and post-weld heat treatment documentation included. EN 10204 3.1 certification standard.

Boiler Industrial SA210A1 Steel Boiler Economizer Heat Exchange Part ASME Certification
Boiler Industrial SA210A1 Steel Boiler Economizer Heat Exchange Part ASME Certification Introduction The H-shaped finned tube is also known as the H-shaped fin tube, also known as the butterfly fin tube. It is to weld symmetrically two pieces of steel with an arc in the middle to form fins (ribs or butterflies), the frontal shape of which resembles the letter "H", so it is called the H-shaped finned tube. The two fins of the H-shaped fin tube are rectangular and approximately
