Applications
Marine & Offshore Systems
  • Seawater Cooled Condensers & Heat Exchangers: Shipboard condensers (main engine cooling), Offshore oil rig heat exchangers (cooling hydraulic systems, lube oil), Desalination plants (multi-stage flash evaporators)
Power Generation (Fossil & Nuclear)
  • Steam Surface Condensers: Coastal/nuclear power plants (seawater-cooled condensers), Waste heat recovery units (exhaust gas boilers)
Chemical & Petrochemical Processing
  • Corrosive Fluid Heat Transfer: Refinery coolers (hydrocarbon processing), Ammonia condensers (fertilizer plants)
HVAC & Refrigeration
  • Chillers & Evaporators: Compact design fits shell-and-tube evaporators (e.g., industrial chillers), Seawater-cooled HVAC (tropical coastal buildings), Industrial refrigeration systems
Industrial Process Cooling
  • High-Temperature/Pressure Exchangers: Meets strict dimensional tolerances for high-pressure systems, Brewery/distillery wort coolers, Pulp & paper mill heat recovery
Mechanical Properties
Property Value
Tensile Strength (UTS) 380 - 520 MPa (55,000 - 75,000 psi)
Yield Strength (0.2% Offset, YS) 140 - 310 MPa (20,000 - 45,000 psi)
Elongation (in 50mm) 35 - 45% (varies with temper)
Hardness (Rockwell B) 50 - 85 HRB
Modulus of Elasticity 100 - 110 GPa (14.5 - 16 Msi)
Strength Considerations
Temperature Effects
  • At Elevated Temperatures (~150-250°C / 302-482°F): Tensile strength decreases by ~20-30%
  • Below 0°C (32°F): Becomes slightly stronger but more brittle (impact resistance drops)
Corrosion & Erosion Impact
  • Dezincification or pitting can reduce effective wall thickness
  • Erosion-corrosion (high-velocity seawater) may accelerate wear
U-Bend Stress Considerations
  • The bent region is work-hardened, increasing local strength
  • Residual stresses from bending may require stress relief annealing
Material Comparison
Material Tensile Strength (MPa) Yield Strength (MPa) Key Advantage
C68700 (Al Brass) 380-520 140-310 Best for seawater corrosion
C70600 (90/10 Cu-Ni) 290-400 120-200 Better sulfide resistance
C71500 (70/30 Cu-Ni) 350-550 140-350 Higher strength than C70600
Titanium Gr. 2 345-483 275-345 Lightweight, no corrosion
Carbon Steel 400-550 205-250 Cheap but rusts easily
Design & Operational Limits
  • Max Allowable Pressure: Depends on tube diameter/wall thickness (use ASME BPVC Section VIII for calculations)
  • Fatigue Life: Excellent for cyclic thermal loads (U-bend accommodates expansion)
  • Avoid: Over-tightening in tube sheets (can collapse thin-walled tubes). Excessive vibration (may cause fretting wear)
Testing & Certification
  • Hydrostatic Test: Ensures no leaks at 1.5x design pressure
  • Eddy Current/UT Testing: Checks for defects affecting strength
  • Certifications: ASTM B111 / ASME SB111, EN 12451 (EU)
