ASME SB111 seamless tubes are commonly used in condensers and evaporators.
ASME SB111 C68700 Material Quality and Composition
Base material, provides excellent thermal conductivity and mechanical strength, Cu:76.0-79.0%
Enhances strength and workability while maintaining corrosion resistance, Zn:Remainder
Improves corrosion resistance, particularly in high-velocity seawater, Al:1.8 – 2.5%
Adds resistance to erosion and impingement, Fe:0.05 – 0.20%
Prevents dezincification, ensuring long-term durability in water systems, As:0.02 – 0.06%
Maintains machinability; low content ensures compliance with environmental regulations such as RoHS, Pb:≤0.05%
ASME SB111 C68700 Product Dimensions and Tolerances
1.Outer Diameter (OD)
Range/Value: 6 mm - 300 mm
Tolerance: For OD ≤ 50 mm, the tolerance is ±0.05 mm; for OD > 50 mm, it is ±0.1 mm.
Note: Precise OD tolerance ensures compatibility in heat exchangers and condensers.
2. Wall Thickness (WT)
Range/Value: 0.5 mm - 10 mm
Tolerance: ±10% of the nominal thickness
Note: Uniform wall thickness ensures consistent mechanical and thermal performance.
3. Length
Range/Value: Up to 12 m
Tolerance: ±5 mm for fixed lengths
Note: Can be customized to meet specific project requirements.
4. Straightness
Range/Value: ≤1 mm/m
Tolerance: Not specifically marked
Note: Ensures easy installation and alignment during assembly.
ASME SB111 C68700 Delivery Condition
Surface Finish: Smooth, bright, and free from defects such as scratches, pits, or oxidation.
Cleaning: Cleaned internally and externally to remove oil, grease, and other residues.
Packaging: Bundled with protective plastic wraps or wooden crates to prevent damage during transit.
Heat Treatment: Supplied in annealed, stress-relieved, or as-drawn condition, depending on customer requirements.
Marking: Tubes are marked with alloy name, size, and batch number for traceability.
Customization: Lengths, finishes, or special coatings (e.g., anti-corrosion) available upon request.
ASME SB111 C68700 Performance Characteristics
1.Tensile Strength
Value: 310 - 450 MPa. Provides high mechanical strength, suitable for demanding applications.
2.Yield Strength
Value: 105 - 220 MPa. Sufficient yield strength for moderate pressure systems.
3.Elongation
Value: ≥ 35%. Good ductility allows for bending, flaring, and forming during fabrication.
4.Thermal Conductivity
Value: ~120 W/M·K Excellent heat transfer efficiency, critical for heat exchangers and condensers.
5.Corrosion Resistance
Value: Outstanding in seawater. Highly resistant to dezincification, impingement, and biofouling in marine environments.
6.Erosion Resistance
Value: High. Aluminum content improves resistance to high-velocity water or turbulent flows.
7.Operating Temperature
Value: Up to 300°C. Suitable for high-temperature industrial and marine applications.
8.Density
Value: ~8.53 g/cm³ Standard density for brass alloys, ensuring manageable weight for installations.
ASME SB111 C68700 Standard Certifications
B111: Standard specification for copper and copper-alloy seamless condenser tubes.
EN 12451 European: standard for copper and copper alloy seamless tubes for heat exchangers.
ISO 19688: International standard for seamless copper-alloy tubes for heat exchangers.
BS2871 Part 3: British standard for seamless tubes for heat exchangers and condensers.
RoHS Compliance:Restriction of Hazardous Substances, ensuring minimal lead content for safety.
NACE MR0175: Ensures suitability for sour service environments where resistance to H2S corrosion is required.
PED Compliance: Pressure Equipment Directive compliance for pressure systems in Europe.
