Heat Exchanger Tube Types
Our heat exchanger tubes are designed for shell-and-tube heat exchangers, evaporators, condensers, chillers, and industrial heat transfer systems. We provide titanium and titanium alloy tubes for corrosion-resistant applications, stainless steel tubes for high-strength and durable operation, and copper or copper alloy tubes for excellent thermal conductivity. Tube materials, structures, tooth profiles, and dimensions can be customized according to working conditions, media, pressure, temperature, and heat transfer requirements.
Titanium and Titanium Alloy Heat Exchanger Tubes
Lightweight, corrosion-resistant tubes for harsh chemical heat exchange.
Stainless Steel Heat Exchanger Tubes
Stable, durable tubes for broad industrial heat exchange applications.
Copper and Copper Alloy Heat Exchanger Tubes
High-conductivity, easily processed tubes for efficient heat exchange.
Titanium and Titanium Alloy Heat Exchanger Tubes
Thermal Conductivity: λ = 15.24 W/(m·K)
Mechanical Properties:
Yield strength: 240–550 MPa; tensile strength: 240–700 MPa; elongation: 15–55%. Lower strength values indicate easier forming, while higher elongation means better ductility.
Corrosion Resistance
Resistant to oxidizing, high-chloride, mildly acidic, and strongly alkaline environments, with wide application suitability.
Processability
Easier to form than stainless steel, but prone to tool adhesion and severe tool wear during machining.
Economic Performance
Titanium is currently priced close to copper. Due to its low density of 4.5 g/cm³, its converted cost is close to 316L stainless steel.
Stainless Steel Heat Exchanger Tubes
Thermal Conductivity:
304/316L: λ = 16.2 W/(m·K); 436/439: λ = 24.2 W/(m·K).
Mechanical Properties:
300 series: yield strength 220–270 MPa, tensile strength 510–580 MPa, elongation 40–65%.
400 series: yield strength 200–230 MPa, tensile strength 400–450 MPa, elongation 20–30%.
300 series stainless steel has stronger work-hardening, while 400 series is less prone to hardening and easier to process.
Corrosion Resistance
Resistant to oxidizing environments, moderate chloride concentrations, general acidic environments, and strong alkaline conditions, offering wide application suitability.
Processability
Relatively difficult to machine. Higher carbon content increases machining difficulty, and plastic hardening becomes significant after processing.
Economic Performance
Cost-effective, especially 400 series stainless steel, which is more economical than 300 series under similar corrosion resistance requirements.
Copper and Copper Alloy Heat Exchanger Tubes
Thermal Conductivity:
Pure copper: λ = 386.4 W/(m·K); aluminum brass: λ = 203 W/(m·K); cupronickel: λ = 40 W/(m·K).
Mechanical Properties:
1.Pure copper: yield strength 70–90 MPa, tensile strength 200–250 MPa, elongation 50–65%.
2.Cupronickel: yield strength 200–230 MPa, tensile strength 350–400 MPa, elongation 35–45%.
3.Aluminum brass: yield strength 200–230 MPa, tensile strength 400–550 MPa, elongation 20–40%.
Corrosion Resistance
A wide range of grades is available, allowing suitable material selection for different operating environments.
Processability
Pure copper is very easy to process, aluminum brass is relatively difficult, and cupronickel offers moderate processability. Overall, copper alloys can be processed into high-efficiency enhanced profiles.
Economic Performance
Copper alloys are relatively expensive and less cost-effective.
Externally Grooved Heat Exchange Tube
Processing Method
Welded or seamless tube blanks are cold-rolled and formed using a three-roll rolling mill.
Product Advantages
1. High finning coefficient for a larger heat transfer surface area.
2. Custom tooth profiles for condensation, falling-film, and flooded heat exchange.
3. Copper and copper alloy finned tubes provide high heat transfer efficiency and flexible material options.
4. Titanium and stainless steel tubes offer strong pressure and corrosion resistance with good cost performance.
Applications
1. Shell-and-tube evaporators, condensers, and other heat exchange equipment.
2. Chemical heat exchangers, reactors, and industrial heat transfer systems.
Internally Grooved Heat Exchange Tube
Processing Method
Serrated metal strips are welded and formed into tubes for stainless steel and titanium materials.Seamless copper tubes are spin-formed for copper materials.
Product Advantages
1. High-efficiency serration rolling with lower production cost, suitable for difficult-to-machine metals.
2. Open-type serration rolling enables high-performance tooth profiles not achievable by conventional spin-forming.
3. Clean processing: metal strips are cleaned before forming, leaving minimal residues.
Applications
Applicable to shell-and-tube dry evaporators, corrosion-resistant air coolers and surface air coolers, evaporative cooling equipment, and non-refrigeration heat exchangers such as heat pipes, condensers, and related equipment.
