Heat Exchanger Tube

-- Steady & Reliable Manufacturer --

Engineered for Thermal Transfer and Mechanical Reliability

Heat Exchanger Tube is a high-performance category of copper tubing designed to facilitate the transfer of thermal energy between two fluids without them mixing. At Zhejiang Jingliang, we treat these tubes as high-precision engineering components rather than simple pipes. The efficiency of a heat exchanger—whether it's a shell-and-tube, plate, or finned-coil design—is dictated by the wall thickness, surface area, and thermal conductivity of the tube. Our heat exchanger tubes are manufactured with "Ultra-Tight Dimensional Tolerances" to ensure they fit perfectly into tube sheets and can be mechanically expanded or flared without cracking. We utilize C12200 and various brass or cupronickel alloys to meet the specific chemical resistance needs of different industrial processes, from HVAC chillers to petrochemical refineries.

A key aspect of our manufacturing is the "Surface Integrity" of the tube. We offer smooth, inner-grooved, and externally finned versions to maximize the heat transfer coefficient according to the Reynolds number of the fluid flow. Our tubes undergo 100% "Eddy Current Testing" to detect any sub-surface imperfections that could lead to a leak under high-pressure industrial cycles. For applications involving high-velocity fluids, we optimize the "Grain Structure" of the copper through controlled annealing to provide the best resistance to erosion and fatigue. Whether you are building a power plant condenser or a simple domestic water heater, Jingliang Heat Exchanger Tubes provide the reliable, high-conductivity foundation needed for efficient thermal management.

Power Plants, Refrigeration, and Process Industry

Heat exchanger tubes are the heart of "Shell and Tube Exchangers" used in oil refineries and chemical processing plants to manage reactant temperatures. In the "Power Generation" industry, they are used for boiler feed water heaters and turbine oil coolers. "HVAC Chillers" utilize large quantities of these tubes in their evaporators and condensers to provide cooling for skyscrapers and hospitals. They are also found in "Food and Beverage Processing," where they are used to pasteurize milk or cool wort in breweries. In the "Automotive" sector, specialized heat exchanger tubes are used for transmission oil coolers and intercoolers. Additionally, they are used in "Desalination Plants" to withstand the corrosive effect of boiling seawater while efficiently transferring heat to produce fresh water.

Thermal Efficiency and Mechanical Durability

The "Highest Thermal Conductivity" of our copper alloys ensures the most efficient heat transfer possible, allowing for "Compact Heat Exchanger Designs." Our "Strict Dimensional Control" ensures a perfect seal when the tubes are expanded into tube sheets, reducing the risk of cross-contamination between fluids. "Excellent Corrosion Resistance" across our range of alloys allows for use with steam, seawater, oil, and various refrigerants. The "High Fatigue Strength" of our tubes ensures they can withstand the "Pressure Pulsations and Thermal Shocks" common in industrial processes. Furthermore, our tubes are "Easy to Fabricate," accepting bending, flaring, and welding with ease. The "Smooth Internal Surface" reduces the buildup of scale and fouling, which "Extends Cleaning Intervals" and maintains system efficiency over time. Finally, the "100% Recyclability" of copper makes it a sustainable choice for industrial infrastructure.

Industrial Packaging and Traceability

Heat exchanger tubes are typically shipped in straight lengths, often bundled in hexagonal packs or "Wooden Crates" with internal supports to prevent sagging. Payment is 30% T/T and 70% L/C. We ship from Ningbo, providing full "Material Traceability" and "Mill Test Certificates" that comply with ASME and EN standards. For large projects, we offer "Custom Cutting" to exact lengths (±1mm), which reduces on-site scrap and labor. Our logistics team handles the complex documentation required for international industrial projects, ensuring all "Quality Assurance" records are clear and complete.

  • Q: How do I choose between smooth and inner-grooved tubes?
  • A: Smooth tubes are standard for many liquid-to-liquid exchangers, while inner-grooved tubes are optimized for phase-change applications like refrigeration where turbulence improves efficiency.
  • Q: Can you provide tubes for seawater applications?
  • A: Yes, for seawater we recommend our C70600 (Copper-Nickel 90/10) or C44300 (Admiralty Brass) heat exchanger tubes for superior corrosion resistance.
