Construction & Component Specifications
Component
Material Standard / Specification
Key Characteristics & Role
U-Bend Tubes
ASME SB111 / C68700 (Aluminum Brass)
Seamless tubes containing approximately 2% aluminum, which forms a tenacious, self-healing oxide layer for superior corrosion and erosion resistance.
Tubesheet(s)
Typically Muntz Metal (C28000) or Naval Brass (C46400)
Chosen for galvanic compatibility with C68700 tubes to minimize electrochemical corrosion at the joint.
Baffles
Typically Naval Brass (C46400) or Coated Carbon Steel
Supports tubes and directs shell-side flow; material selected for compatibility with the water environment.
Tie Rods & Spacers
Brass or Coated Carbon Steel
Maintains precise baffle spacing and structural integrity of the bundle.
Headers / Water Boxes
Cast or Fabricated from C95800 (Ni-Al Bronze) or Coated Steel
Provides distribution/collection chambers; often lined or made from superior corrosion-resistant material for extended service life.
Technical Highlights & Advantages
Superior Marine-Grade Protection: The aluminum content in C68700 alloy forms a hard, adherent protective oxide film (Al₂O₃) that offers outstanding resistance to dezincification, impingement attack, and stress corrosion cracking in seawater, brackish water, and cooling tower water.
Enhanced Flow Efficiency: The smooth, seamless U-bend tubes minimize pressure drop and allow for efficient, compact heat exchanger designs with large surface areas.
Proven Reliability: The monolithic U-bend eliminates a potential failure point (the second tubesheet joint), reducing leakage risks and improving longevity under thermal cycling.
Full Customization: We engineer each bundle to match original dimensions, tube count, bend radius, and baffle design, ensuring a perfect drop-in fit for your existing condenser or heat exchanger.
Typical Applications & Value
Critical Cooling Systems: The premier choice for power plant surface condensers, shipboard heat exchangers, seawater cooling systems, desalination plant components, and industrial cooling water circuits.
Lifecycle Cost Savings: Exceptional corrosion resistance translates to longer service intervals, reduced maintenance costs, and avoidance of costly unplanned downtime caused by tube failures.
Optimized Thermal Performance: Maintains high heat transfer efficiency over extended periods by resisting fouling and scaling more effectively than some copper-nickel alloys in certain water conditions.
