Product Description Product Description1. Standard CompliancePrimary Standard: ASME SA210 (Seamless Medium-Carbon Steel Boiler & Superheater Tubes).Complementary Standards:ASME B36.10M (Dimensions & Tolerances).ASME Sec. I (Power Boiler Applications).EN 10216-2 (EU Equivalent: P195/P235/P265).2. Dimensional SpecificationsParameterToleranceOD Tolerance±1% (Hot-Finished) / ±0.5% (Cold-Drawn)Wall Thickness Tolerance+12.5%, -10%U-Bend Ovality≤8% of OD (Post-Bending)3. Performance Advantages High-Temperature Stability - Retains strength up to 450°C (Grade C preferred for superheaters). Corrosion & Oxidation Resistance - Ferritic structure resists steam erosion. Custom Bend Radii - 1.5D to 5D for compact heat exchanger layouts.4. Quality AssuranceChemical Composition (Grade C Example):ElementSA210 Grade C RequirementC≤0.35%Mn0.29-1.06%P≤0.035%S≤0.035%Mechanical Tests:Tensile Strength: ≥485 MPa (Grade C).Yield Strength: ≥275 MPa (Grade C).Hardness: ≤179 HB (Annealed Condition).5. Application ScenariosPower Plants: Superheater/reheater coils, boiler U-bends.Heat Exchangers: Condensers, economizers.Industrial Steam Systems: High-pressure steam distribution.6.
