Transparent quartz glass twin tube
Dalian Xuri (Sunrise) Quartz Glass Co., Ltd. manufactures transparent quartz glass twin tubes from fused silica with a purity greater than 99.99% SiO2. The product is available in three inner bore dimensions - 33 × 16 mm, 22 × 11 mm and 18 × 9 mm - and can be produced up to a length of 6.5 m per tube. The tubes are produced in a single‑step patented process that eliminates air lines and bubbles, delivering excellent verticality and minimal bow. Each batch can be made to customer drawings and is accompanied by an inspection report before delivery.
In the optics and semiconductor sectors, fused silica tubes of this grade typically exhibit an optical transmission above 95 % across the visible spectrum and a thermal expansion coefficient around 0.55 × 10⁻⁶ /K. Standard dimensional tolerances for the inner bore are ±0.05 mm, while outer diameter tolerance is ±0.1 mm, ensuring compatibility with precision equipment. Typical surface roughness is below 10 nm RMS, which supports high‑purity fluid transfer and minimal light scattering. These industry norms align with the specifications offered by Xuri, though exact tolerances should be verified for each order.
The twin tubes are sought by manufacturers of semiconductor processing equipment, solar photovoltaic modules, laboratory fluid handling systems and fiber‑optic components. Xuri ships the tubes in wooden crates or protective pallets, with custom packaging available for long lengths. Importers need to confirm the minimum order quantity, preferred Incoterm - commonly FOB Dalian or CIF a destination port - and payment schedule with the supplier. Given the supplier’s harbor trust tier and zero response rate, buyers should initiate contact early to secure detailed quotations and lead‑time estimates.

Sourcing Transparent quartz glass twin tube from Dalian Xuri (Sunrise) Quartz Glass Co., Ltd. - China Import Guide
