Import Big Diameter Quartz Glass Tube — Buy in wholesale FOB from Supplier in China

This big diameter quartz glass tube from Dongxin Quartz Products Co., Ltd. is manufactured from fused silica with a purity of SiO2 99.99%, sourced from Lianyungang in Jiangsu province. The tube features large outer diameters with consistent wall thickness, engineered for applications where thermal shock resistance and optical clarity are critical. Custom lengths are available to project requirements, and the material offers excellent chemical resistance alongside its thermal stability.

Fused silica quartz glass differs from standard borosilicate or soda-lime glass in its extremely low thermal expansion coefficient, typically around 0.55 x 10^-6 per degree Celsius, which allows rapid heating and cooling without fracture. The 99.99% SiO2 content places this material in the highest purity grade for industrial quartz, minimising contamination in sensitive processes. Standard wall thickness ratios for large-diameter quartz tubes typically range from 5% to 10% of outer diameter, though the exact tolerances for this listing should be confirmed directly with the supplier. The optical transmission of fused silica extends from ultraviolet through infrared wavelengths, making it suitable for applications beyond visible light requirements.

Primary buyers include semiconductor equipment manufacturers using chemical vapor deposition chambers, optical instrument makers requiring UV-transparent components, and research laboratories running high-temperature experiments. Industrial users in chemical processing value the material's inertness to most acids and bases. When sourcing from Dongxin Quartz Products Co., Ltd., buyers should confirm outer diameter range, wall thickness tolerance, maximum continuous operating temperature, and surface finish specifications. Packaging is described as reliable for international transport, though specific crating or cushioning methods should be verified before ordering.

Dongxin Quartz Products Co., Ltd. is located at No.303 Fuhua Road, Donghai Economic Zone, Lianyungang 222300, Jiangsu, China. The company operates as an imported-tier supplier on this platform with a harbor trust designation. The response rate is recorded at 0.00% with an average response time of 0 hours, which indicates no response history is currently available through this channel. Buyers should initiate direct contact to assess communication reliability and technical support capabilities before committing to orders.

The listing profile does not disclose manufacturing floor space, employee count, annual output, specific client references, or years in operation. No certifications such as ISO 9001 or SEMI standards are stated in the available data. The company specialises in quartz glass products, with this particular offering focused on large-diameter fused silica tubes for industrial and scientific markets. The absence of verified response signals means due diligence through direct enquiry, sample requests, and reference checks becomes essential. Buyers should request material certificates of analysis, dimensional inspection reports, and packaging specifications to establish baseline quality assurance.
