Heat Exchanger Copper Tube

-- Steady & Reliable Manufacturer --

Engineered for Thermal Transfer and Heavy Industrial Performance

Heat Exchanger Copper Tubes are specialized industrial conduits engineered to transfer thermal energy between fluids efficiently in shell-and-tube heat exchangers, condensers, evaporators, and boilers. Used extensively in power generation, petrochemical processing, marine engineering, and large-scale HVAC industrial plants, these tubes are the foundation of energy recovery and thermal management. At Zhejiang Jingliang, our heat exchanger copper tubes are manufactured using high-grade C12200 phosphorus-deoxidized copper, C11000 ETP copper, or copper alloy options such as Cu-Ni (C70600 / C71500) and Brass (C26000 / C68700), complying with international standards like ASTM B111, ASME SB111, and EN 12451.

To maximize thermal performance, we produce heat exchanger copper tubes in plain smooth bore, inner-grooved (micro-fin), and low-finned exterior geometries. The low-finned design increases the external surface area by up to 2.5 times without increasing tube outer diameter, boosting heat transfer performance while saving vessel space. Our manufacturing process involves strict cold drawing, precision straightening, bright annealing, and 100% non-destructive eddy current testing to guarantee wall thickness uniformity and eliminate surface defects. Jingliang heat exchanger copper tubes withstand aggressive fluid flow velocities, high thermal shocks, and corrosive operating environments with long service life.

Shell-and-Tube Condensers, Power Plants, and Marine Desalination

Heat exchanger copper tubes are widely deployed in "Shell-and-Tube Heat Exchangers" and "Steam Surface Condensers" in power generation plants. They are essential in "Seawater Desalination Plants" and "Marine Oil Coolers" where salt-water corrosion resistance is critical. Petrochemical refineries use them in "Process Liquid Coolers" and "Gas Compressors." They are also standard in "Industrial Boiler Economizers," "Distillery Evaporators," "Food and Dairy Pasteurization Lines," and "Large Commercial Centrifugal Chillers."

Optimal Heat Transfer Coefficient and Resistance to Erosion-Corrosion

The primary advantage of our heat exchanger copper tube is its "High Thermal Transfer Efficiency," which reduces the required surface area and footprint of heat exchanger vessels. Their "Superior Ductility" allows clean 180-degree U-bends and reliable mechanical roller expansion into tube sheets without cracking. Excellent "Erosion and Corrosion Resistance" protects against aggressive cooling water velocity and bio-fouling. The "Precision Outer Diameter Tolerance" ensures seamless assembly into baffles and end plates, "Minimizing Pressure Drop and Flow Turbulence."

Heavy Wooden Box Packaging and Global Shipping Logistics

Straight and U-bent heat exchanger tubes are packed in heavy-duty wooden cases lined with waterproof plastic sheeting to prevent transit damage. Ends are fitted with protective caps. Payment terms are 30% T/T deposit and 70% L/C at sight. Shipments are dispatched through Ningbo or Shanghai ports, fully backed by "ASME Material Test Reports (MTR)," "Hydrostatic Test Certificates," and "Dimensional Verification Reports."

  • Q: Do you supply U-bent heat exchanger copper tubes?
  • A: Yes, we provide custom U-bend heat exchanger tubes with stress-relief annealing on the bent section according to ASTM B111 specifications.
  • Q: Which alloy is best for seawater cooling environments?
  • A: For seawater applications, C70600 (Copper-Nickel 90/10) or C68700 (Aluminum Brass) is highly recommended due to its exceptional resistance to marine bio-fouling and erosion.
