ASME SB111 C68700 Aluminum Brass U-Bend Tube Bundle | Corrosion Resistant for Seawater & Cooling Water Service
Yuhong Holding Group Co., Ltd. is a specialized manufacturer of critical thermal management equipment. Through our TEMA Heat Exchanger platform, we deliver custom shell & tube heat exchangers, pressure vessels, air coolers, and a full range of precision-engineered replacement components, including tube bundles (straight & U-bend), finned tubes, and all essential parts. Our expertise ensures reliable performance in the most demanding conditions.
This U-bend tube bundle is manufactured from ASME SB111 C68700 aluminum brass, an alloy specifically formulated for exceptional resistance to impingement attack and corrosion in high-velocity, saline, or polluted waters. The integral U-bend design enhances mechanical reliability by eliminating one tubesheet joint, making it an ideal, durable core for condensers and heat exchangers in challenging cooling applications.
Construction & Component Specifications
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.
