Industrial Heat Exchanger Tubes

-- Steady & Reliable Manufacturer --

The Heart of Industrial Thermal Management

Industrial heat exchanger tubes are specialized components designed to transfer thermal energy between two fluids with maximum efficiency and minimum pressure drop. In a world where energy conservation and process optimization are paramount, the performance of the heat exchanger tube is the deciding factor in the overall efficiency of power plants, refineries, and large-scale HVAC systems. At Zhejiang Jingliang, we produce a wide range of heat exchanger tubes, including smooth-bore, inner-grooved, and finned varieties. These tubes are engineered to withstand not only the thermal stresses of constant heat transfer but also the mechanical stresses of high-pressure fluid flow and the chemical stresses of potentially corrosive cooling media. We utilize advanced metallurgical techniques to ensure that our tubes have a consistent grain structure, which is critical for both heat conductivity and the mechanical strength required for tube-to-tubesheet expansion.

The manufacturing of industrial heat exchanger tubes requires a level of precision far beyond standard plumbing pipe. Every tube must be 100% defect-free, as a single leak in a large-scale condenser or boiler can lead to catastrophic system failure and massive financial losses. We employ 100% online Eddy Current Testing (ECT) and hydrostatic testing to guarantee the integrity of every centimeter of tubing we ship. We also offer specialized surface treatments and material grades, such as copper-nickel alloys or high-purity C12200, to suit different industrial environments—from seawater cooling to high-pressure steam. Our engineering team works closely with OEM designers to optimize the tube geometry for their specific application, whether that means adjusting the helix angle of inner grooves or providing custom-bent U-tubes for compact heat exchanger designs. By focusing on the intersection of thermodynamics and material science, we provide the industrial sector with the high-performance components needed for the next generation of thermal management systems.

Applications in Energy and Manufacturing

Industrial heat exchanger tubes are found in nearly every sector of heavy industry. In power generation, they are the primary components in surface condensers and feedwater heaters, where they facilitate the cooling of steam back into water. In the petrochemical and oil & gas industries, these tubes are used in process condensers and reboilers to manage the temperatures of various hydrocarbon streams. They are also essential in the desalination industry, where they must resist the highly corrosive nature of brine. In large-scale HVAC applications, they form the "guts" of water-cooled chillers and evaporative condensers for district cooling systems. Other applications include marine heat exchangers for ship engines, industrial refrigeration for food processing, and solar thermal concentrators. The diversity of these applications requires a manufacturer that can provide a wide range of sizes, tempers, and alloy compositions, all while maintaining the strict quality standards required for high-stakes industrial operations.

Advantages of Jingliang Heat Exchanger Tubes

The primary advantage of our heat exchanger tubes is their superior reliability. Our proprietary drawing and annealing processes ensure that the tubes are free from residual stresses, which significantly reduces the risk of stress corrosion cracking (SCC) in service. This reliability is backed by our comprehensive testing regime, which includes ultrasonic, eddy current, and pneumatic tests. Another advantage is our ability to provide customized internal geometries, such as micro-grooving, which can increase the internal heat transfer coefficient by over 100% compared to smooth tubes. This allows engineers to design smaller, more cost-effective heat exchangers. Our tubes also feature exceptionally tight dimensional tolerances, ensuring a perfect fit during the tube-rolling or expansion process into the tubesheet, which minimizes the risk of joint leaks. Furthermore, our focus on high-purity materials ensures maximum thermal conductivity, which directly translates to lower operational costs and a smaller carbon footprint for the end-user's facility.

Global Logistics, Packaging, and Payment

Because industrial heat exchanger tubes are often very long (up to 12 meters), they require specialized logistics. We use custom-made, heavy-duty steel-reinforced wooden crates to prevent any bending or surface damage during sea transport. For large-scale projects, we coordinate closely with freight forwarders to provide "vessel-side" delivery to major global ports. Payment is typically handled via L/C at sight for large project orders, though T/T is also accepted. We provide comprehensive documentation, including detailed Mill Test Certificates, third-party inspection reports (if required), and material traceability records. Our factory is equipped to handle "Emergency Repair" orders, where we can fast-track the production of specific tube sizes to help a plant minimize downtime during an unscheduled outage. Every shipment is optimized for space and safety, ensuring your project stays on schedule and on budget.

  • Q: Do you offer U-bent tubes for heat exchangers?
  • A: Yes, we have specialized bending equipment to provide U-tubes according to your specific blueprints, including stress-relieving annealing on the U-bend area to prevent cracking.
  • Q: What testing do you perform for industrial-grade tubes?
  • A: Every tube undergoes 100% Eddy Current Testing. Depending on the specification, we also perform hydrostatic testing, pneumatic testing, and various mechanical tests like flaring, flattening, and grain size analysis.
  • Q: Can you help with material selection for corrosive environments?
  • A: Our technical team can provide advice based on your fluid composition. For example, for seawater cooling, we often recommend our C70600 Copper-Nickel tubes for their superior resistance to biofouling and corrosion.
