The Dongyingtaixiao Trade Company offers a harmonica‑shaped aluminum tube designed for heat‑exchange systems. The tube is fabricated from alloy 3003 and measures 5 mm by 37 mm in cross‑section. Each unit contains seven precision‑drilled holes that promote rapid fluid flow. The part is supplied in bulk with sea‑ready packaging as described in the source.
Alloy 3003 provides good corrosion resistance and excellent formability, traits valued in HVAC and industrial cooling equipment. In the sector, similar corrugated tubes are often produced with wall thicknesses of 0.5 - 1.0 mm, a typical range for aluminium heat exchangers. The tube’s compact geometry aligns with standard design practices for compact radiators where space is limited. Manufacturers frequently choose such tubes for their balance of strength and thermal conductivity, a standard performance expectation.
The primary application is as a component in aluminium‑tube radiators used in commercial and residential HVAC installations. Importers of cooling units, system integrators and equipment manufacturers are typical buyers of this product. The supplier ships the tubes in sealed containers with standard sea freight terms, and packaging complies with export regulations. Prospective buyers should request the exact packaging dimensions and confirm Incoterms before placing an order.

Before placing an order, buyers should verify the alloy grade, exact dimensions and hole pattern of the harmonica‑shaped tube. Request a mill test report that confirms the 3003 composition and the tolerance on wall thickness. Confirm that the packaging complies with export regulations and that the shipment will be sealed against moisture. Any deviation from the stated specifications should be clarified with Dongyingtaixiao Trade Company.
Shipping is normally arranged under standard sea‑freight terms, but the specific Incoterm (FOB, CIF or others) must be agreed with the supplier. Lead times are not published, so ask for the expected production and dispatch schedule. Payment methods are typically negotiated directly; common practice includes a letter of credit or advance payment. Ensure that the chosen payment and delivery terms are documented in the contract.
Importers should schedule a pre‑shipment inspection to confirm the tube’s dimensions, hole count and corrosion‑resistance coating. An independent third‑party laboratory can verify thermal conductivity if required. Request the full set of test certificates, packaging list and a commercial invoice to facilitate customs clearance. Maintaining a clear record of these documents helps resolve any disputes after arrival.
