What information do you need to engineer a custom quartz tube or component?

Please send outer and inner diameter (or wall thickness), length, required tolerances, end configuration (open, closed, flanged, ground joint or welded fittings), material grade (transparent or opaque fused quartz), working temperature and atmosphere, annual or batch quantity, and a drawing in PDF, DWG or STEP format. Complete data lets our engineers confirm manufacturability and lead time in a single review.

What is the maximum operating temperature of fused quartz?

Transparent fused quartz typically supports continuous service around 1,100 °C and short exposures up to roughly 1,250 °C, with a softening point near 1,683 °C. Real limits depend on grade, load, atmosphere and cycle time. Above about 1,100 °C, surface contamination such as alkali residue from skin contact accelerates devitrification, so quartzware should be cleaned and handled with clean gloves before firing.

How does Southeast Quartz verify quality before shipment?

Products undergo helium mass-spectrometry leak detection, pressure resistance testing and purity testing before leaving the factory, together with dimensional inspection against the customer drawing, to ensure stable performance with no impurities and no leakage.

Can you manufacture oversized quartz tubes and non-standard quartz shapes?

Yes. Our workshop combines flame hot-working with CNC cold machining, so we produce oversized fused quartz tubes, bell jars, slotted quartz boats, flanged reactors, irregular shaped quartz sheets and fully customized quartz instruments according to customer equipment parameters.

Where is Southeast Quartz located and which markets do you export to?

Our factory is at No. 1 Qingsheng Rd., Qinghu Industrial Park, Donghai County, Jiangsu, China, within China's best-known crystal and quartz industrial cluster. Besides customers throughout China, we export to Europe, the Americas, Southeast Asia and the Middle East.

Frequently Asked Questions

Q What is the maximum operating temperature for quartz glass?

Quartz glass can withstand a short-term use temperature of up to 1300 °C and a long-term use temperature of up to 1100 °C. Its thermal processing temperature ranges from 1750 °C to 2050 °C, making it suitable for high-temperature industrial applications.

Q What material is this quartz glass made from?

This quartz glass is made from Silicon Dioxide (Natural Quartz). It is transparent or colorless in appearance, with a surface free of air bubbles and lines, ensuring excellent optical clarity and structural integrity.

Q What thickness options are available for the quartz glass?

The quartz glass is available in thicknesses ranging from 2MM to 20MM, and is produced in a circular shape. Custom thickness requirements within this range can typically be accommodated based on application needs.

Q What is the thermal expansion coefficient of this quartz glass?

The quartz glass has an exceptionally low thermal expansion coefficient of 5.5 × 10⁻⁷ cm/cm·°C. This ultra-low value makes it highly resistant to thermal shock and dimensional changes under extreme temperature fluctuations.

Q What PPM purity grades are available for this quartz glass?

The quartz glass is available in controlled purity grades of 10 PPM, 20 PPM, and 100 PPM. These grades allow customers to select the appropriate level of purity based on their specific semiconductor, optical, or industrial requirements.

Q How does the compressive strength of quartz glass compare to its flexural strength?

Quartz glass exhibits a very high compressive strength of 1100 MPa, making it extremely resistant to compressive forces. Its flexural strength is 67 MPa, which is lower by comparison, indicating that while it handles compression exceptionally well, care should be taken to avoid bending stresses in structural applications.
