Import Clear Quartz Tube — Buy in Bulk from Supplier in China

Lianyungang Inpu Quartz Co., Ltd. supplies clear quartz tubes made from fused quartz glass with a silica content exceeding 99 per cent. The tubes are offered with outer diameters from 2.5 mm up to 300 mm, wall thicknesses between 0.5 mm and 6 mm, and lengths ranging from 20 mm to 3000 mm. Each tube is produced by a continuous melting process that yields high transparency and uniform walls. The supplier lists these dimensional ranges as the standard product catalogue.

The high silica composition gives the tubes excellent resistance to thermal shock and a coefficient of thermal expansion around 0.5 × 10⁻⁶ / °C, which is typical for fused quartz. In practice the material can tolerate temperature changes of several hundred degrees per minute without cracking. Such properties are valued in optical and electronic components where dimensional stability is critical. Industry practice also expects a maximum operating temperature near 1100 °C for similar quartz tubing.

These tubes are commonly installed in laboratory reactors, semiconductor processing equipment, and precision optics assemblies. The supplier states that bulk packaging is provided in sturdy wooden crates with internal padding, and that both FOB and CIF incoterms are available. Because the listing does not disclose a minimum order quantity or lead time, buyers should request those details directly. Payment terms and inspection procedures are also to be confirmed with the supplier before finalising a contract.

Lianyungang Inpu Quartz Co., Ltd. is located at No.113, Daning Road Fangshan Industry Zone, Lianyungang 222341 Jiangsu, China. The company is classified as an imported‑tier supplier with a harbour‑level trust tier, although the platform records show a response rate of zero and no average response time, indicating that communication should be initiated proactively.

The firm specialises in the manufacture and export of fused quartz glass components, including tubes, rods and plates. Its product range is marketed to buyers requiring high purity silica and thermal stability, and the company highlights its ability to meet custom dimensional requests.
