Changzhou Joyruns Steel Tube Co., Ltd supplies a double‑wall zinc‑coated Bundy tube with an outer diameter of 4.76 mm and a wall thickness of 0.6 mm, manufactured from low carbon steel of SPCC/SPCD grade. The product description notes that the double‑wall construction enhances leak resistance and thermal conductivity, making it suitable for refrigeration and air‑conditioning condenser coils.
The tube’s zinc coating provides superior corrosion protection; typical coating thickness ranges between 5 µm and 10 µm. Standard industry practice gives this size a pressure rating of about 1.0 MPa and an operating temperature range of - 20 °C to 120 °C. The product is typically aligned with EN 10326 for steel tubing and may be supplied with ISO or CE certificates, though buyers should request confirmation.
Applications include commercial and residential HVAC systems, refrigeration units and automotive condensers. Changzhou Joyruns offers flexible order quantities and can ship under FOB or CIF terms, but the listing does not state exact MOQ, lead time or pricing. Prospective buyers should contact the supplier to verify these trade details and to obtain any required certification documents.

Confirm that the low carbon steel grade, zinc coating thickness and double‑wall construction meet your engineering specifications. Request a mill test report and coating certification before finalising the purchase.
Discuss logistics with the supplier: ask for preferred Incoterms such as FOB or CIF, request an estimate of production lead time and shipping schedule, and note that the current response rate is 0.00 %, so allow additional time for correspondence. Clarify payment terms and any required deposits.
Arrange quality inspections prior to shipment. Verify dimensional tolerances, pressure rating and coating thickness through third‑party testing or supplier‑provided certificates. Ensure the packaging format (coil or bundle) matches your handling facilities and request pre‑shipment inspection reports.
