Quality description:

The SiO2 purity of fused quartz tube made of quartz sand is ≥ 99.98%, which working temperature for a long time is around 1100c (after annealing or dehydroxylation: 1200C). And the melting point is around 1730c. The SiO2 purity of fused quartz tube made of high-purity quartz sand is ≥ 99.995%, Which working temperature for a long time is around 1200C (after annealing or dehydroxylation: 1300C). In actual use, the difference between the two kinds of pipes is not very obvious, but the cost gap will be large. In general, if there is no specific requirement, we will decide which material to use according to different use purposes.

Through obsersation of fused quartz tube’s surface, it can be marked as be superior products if no bubble, no ray, and no defect. Qualified products if only 1-2 small bubbles.

In terms of discoloration, fused quartz tube can be divided into dehydroxylation discoloration that it can become black, brown and yellow at high temperature. Usually, this kind of quartz tube is due to the fact that the material is relatively high in impurity such as blackening is generally high in iron. No discoloration at high temperature is mean that it is high in purity and durable.

Main functions of fused quartz tube: high temperature resistance, high UV transmittance, acid and alkali resistant and anticorrosion(except dehydrofluoric acid).

Application fields: UV sterilization lamp, chemical industry, scientific research, semiconductor, high frequency furnace, liquid level meter, etc

Specification:

Fused Quartz Glass Tubes are available from OD2mm to OD500mm. The wall thickness ranges from 0.5mm to 10 mm. Larger diameter, Thicker the wall. Generally, the length of common is 1240mm. And the large diameter is generally between 200mm and 300mm.

Distinguish:

Ⅰ. Fused Quartz Glass Tube are distinguished by color as follows:

Transparent and colorless, milky white (opaque), red, yellow, black, gray, purple and so on. Quartz tubes of different colors are made of fused quartz because different processes produce out different colors. Common transparent quartz tubes have better physical and chemical properties. Our company mainly supplies two types of fused quartz tubes: transparent and opaque. The specifications and sizes of transparent or clear fused quartz tubes are more, but the opaque ones are less.

Ⅱ. According to use, Fused Quartz Glass Tube can be divided into:
1. UV sleeve
2. Thick wall quartz tube for position meter(boiler tube)
3. Quartz tube for medium and high frequency furnace
4. Quartz tube for tubular furnace
5. Quartz tube for ozone generator (high ozone quartz tube, no ozone quartz tube, UV filter quartz tube)
