U Bend And Finned Tube
The U‑Bend and Finned Tube offered by Unidus Hk Cooperation is an aluminium‑clad copper (ACC) heat‑exchange tube featuring an outer layer of 3003 aluminium alloy bonded to an inner core of oxygen‑free copper (OFE Cu 99.99%). The tube’s composition yields a copper‑to‑aluminium weight ratio of 30 % to 70 % and a volume ratio of 10 % to 90 %. Mechanical testing records a tensile strength of 115 MPa, elongation of 35 % and an expansion coefficient of 40 % under standard conditions. The bulk density of the finished tube is measured at 4.3 g cm‑3.
The ACC construction combines the high thermal conductivity of copper with the lightweight, corrosion‑resistant properties of aluminium, making it a cost‑effective alternative to solid copper tubes. In the heat‑exchanger industry, such tubes are typically manufactured to meet ASTM B221 for aluminium alloy and ASTM B170 for copper, ensuring consistent metallurgical bonding. Standard dimensions for U‑bend ACC tubes range from 10 mm to 30 mm outer diameter with a wall thickness of 1.5 mm to 3 mm, although custom sizes can be requested. Typical fin spacing is 2 mm to 5 mm, providing enhanced surface area for heat transfer.
Major buyers include manufacturers of HVAC systems, commercial refrigeration units, power‑plant condensers and industrial dehumidifiers that require reliable heat‑exchange performance. Importers should confirm the exact tube dimensions, fin geometry and required standards with Unidus Hk Cooperation before finalising an order. Because the supplier’s profile does not list MOQ, lead time or payment conditions, these trade details must be negotiated directly with the company.

Unidus Hk Cooperation is located at 556 Renmin Road, Tangshi, Suzhou, Jiangsu Province, 215687, China. The company holds a harbor trust tier on the platform, though its response rate is currently shown as zero, indicating that communication may need proactive follow‑up. Unidus specialises in the production of aluminium‑clad copper heat‑exchange tubes for industrial applications.
The supplier’s catalogue highlights ACC tubes with U‑bend and finned configurations, designed for HVAC, refrigeration and power‑plant condenser markets. While the profile does not disclose specific certifications such as ISO 9001, buyers can request relevant test reports or conformity certificates. All enquiries should be routed through the platform’s messaging system and the buyer should verify the supplier’s lead‑time and payment terms before contracting.
ACC aluminum clad copper tubes feature an outer layer of antirust 3003 aluminum alloy bonded to an inner layer of oxygen-free copper, providing excellent thermal conductivity and corrosion resistance for heat exchanger applications. These U-bend and finned tubes are widely used in HVAC systems, refrigeration, power plant condensers, and industrial heat transfer equipment. Available in standard sizes with metallurgically bonded copper-aluminum interfaces, these bimetal tubes offer a cost-effective alternative to solid copper while maintaining superior heat exchange performance for global export markets.

Sourcing U Bend And Finned Tube from Unidus Hk Cooperation - China Import Guide
When sourcing ACC U‑bend and finned tubes from Unidus Hk Cooperation, first obtain the detailed drawing and material certification to confirm the 3003 aluminium outer layer and OFE copper core meet your project specifications. Verify the tube’s outer diameter, wall thickness and fin spacing against the engineering requirements, and request a sample for dimensional inspection. Ensure that the supplier can provide test reports for tensile strength and corrosion resistance before committing to a purchase.
Discuss logistics early to decide on an appropriate Incoterm, such as FOB Suzhou or CIF Shanghai, and agree on the expected production lead time once the order is confirmed. Because the supplier’s response rate is listed as zero, establish a reliable communication channel and confirm payment terms, for example a 30 % deposit via L/C with balance against documents. Clarify any required export licences, customs documentation and freight forwarding arrangements to avoid delays at the port.
Plan for a third‑party pre‑shipment inspection to check the metallurgical bond, dimensional tolerances and fin quality. Request the inspection agency to provide a full report, including any non‑conformities, which can be used for customs clearance and quality assurance. Maintaining these verification steps will help ensure that the delivered tubes perform as intended in HVAC or power‑plant heat‑exchanger systems.
