Quartz glass tube
Heyuan Xinda Quartz Technology Co., Ltd. manufactures quartz glass tubes from high‑purity fused silica (SiO₂ > 99.5%). The tubes are milky quartz type and provide an infrared transmissivity of 70‑75 % without any surface coating. Standard product dimensions include OD 10 mm × wall 1 mm × 2500 mm, OD 10 mm × wall 1 mm × 2250 mm and OD 23 mm × wall 20 mm × 2250 mm. These specifications are listed in the supplier’s source description.
Milky quartz glass is widely used where infrared radiation must pass through a stable glass medium, such as in infrared heating elements for ovens, HVAC equipment and laboratory furnaces. In the glass industry, a typical purity grade for such applications is >99.5 % SiO₂, and wall‑thickness tolerances are usually ±0.05 mm. The absence of coating gives the tube excellent chemical resistance, matching the standard for corrosive‑free environments. The thermal stability allows continuous operation at temperatures up to 1100 °C, a common limit for fused silica components.
Primary buyers include equipment manufacturers, thermal‑process engineers and research laboratories that require reliable infrared emitters. The supplier lists the tubes as ready for export, but does not disclose minimum order quantity, price or specific Incoterms; interested importers should request a formal quotation. Shipping is typically arranged from the port of Guangzhou or Shenzhen, and payment terms are negotiated per contract. Verification of material certificates and dimensional drawings is recommended before placing an order.

Sourcing Quartz glass tube from Heyuan Xinda Quartz Technology Co., Ltd. - China Import Guide
Before placing an order, importers should request the supplier’s mill test report confirming SiO₂ purity, infrared transmissivity and dimensional tolerance. Comparing the reported dimensions with a CAD drawing helps avoid mismatches, especially for custom‑length orders. It is also advisable to verify the supplier’s export licence and any relevant customs documentation for quartz glass products.
Logistics for Heyuan‑based suppliers usually involve freight from the ports of Guangzhou or Shenzhen. Buyers should confirm the expected lead time, which is not disclosed in the listing, and negotiate Incoterms such as FOB, CIF or DDP according to their risk preference. Payment terms are typically negotiated per contract; common options include a TT advance payment followed by a balance against shipping documents, but the exact terms must be agreed with the supplier.
Quality assurance for quartz glass tubes often includes visual inspection for cracks, dimensional verification with calibrated gauges, and infrared transmissivity testing using a spectrophotometer. Request a certificate of conformity or an ISO‑based quality audit if required by your market. Independent third‑party inspection prior to loading can further reduce the risk of receiving non‑conforming batches.
