What are the different types of deep processing for quartz tubes?

Quartz products are highly popular instruments with a wide range of applications. Thanks to their excellent and stable performance, they are extensively used in various fields. Quartz glass tubing is one common application of quartz, and it comes in many different types. Below is an overview of the main varieties: clear quartz tubes, opal‑white quartz tubes, quartz rods, quartz sleeves, quartz sheets, quartz laboratoryware, as well as assorted bent quartz tubes, spherical quartz tubes, custom‑shaped quartz tubes, and colored quartz tubes.

Quartz tubes offer stable performance and are widely favored in both industrial production and everyday life. They undergo advanced processing without the use of coatings, providing a consistent emissivity, maintaining dimensional stability at high temperatures, emitting no harmful radiation, causing no environmental pollution, and exhibiting excellent resistance to high temperatures and corrosion. They also boast superior chemical stability, low thermal inertia, rapid thermal response, and high thermal conversion efficiency. Users can independently set the heating temperature, and their radiative properties remain unchanged over long-term use. With a well‑designed structure, they are easy to operate. Quartz tubes are the preferred choice in China for selective far‑infrared heating applications, offering broad versatility and strong adaptability. They are extensively employed in heating and drying processes across industries such as mechanical and electrical engineering, chemistry, electronics, textiles, printing and dyeing, plastics, printing, grain processing, food manufacturing, medical and sanitary fields, and leatherworking—supporting curing, dehydration, and other operations in various types of drying tunnels, chambers, and ovens. Moreover, quartz tubes are particularly well suited for pharmaceutical and sanitary applications, research laboratories, and environments requiring robust performance under corrosive conditions, including those involving acids and alkalis.

We offer quartz tubes in a wide range of specifications, including transparent, pearlescent, UV‑transmitting, and UV‑sterilizing types, with diameters from 2 to 180 mm, wall thicknesses from 0.5 to 8 mm, and lengths from 10 to 2,000 mm. Our product lineup also includes fused quartz tubes, dehydroxylated tubes, UV‑filtering tubes, and ozone‑free tubes. Standard fused quartz tubes achieve SiO₂ purity exceeding 99.6%, exhibiting excellent geometric dimensions, chemical stability, thermal stability, resistance to thermal shock, and resistance to crystallization, with optical transmittance surpassing 90%. Dehydroxylated tubes maintain hydroxyl levels below 10 ppm; through specialized processing, hydroxyl content can be reduced to under 5 ppm. Pearlescent tubes are a new‑process variant of milky‑white tubes, featuring a surface that resembles the luster of pearls, ideal for manufacturing heating elements, infrared heaters, and far‑infrared lamps. UV‑filtering tubes effectively block harmful ultraviolet wavelengths in the 190–320 nm range, making them well suited for eco‑friendly light sources. In contrast, ozone‑free tubes transmit UV radiation around 253.7 nm, widely employed for sterilization in medical devices, water treatment, food sanitation, and other applications. We also provide machining services for quartz plates, quartz sleeves, quartz water jackets, quartz wafers, quartz ingots, quartz rings, quartz boats, and various custom‑shaped quartz tubes, and we manufacture low‑ozone quartz tubes for UV‑sterilization lamps.

Quartz sleeves range in diameter from 8 to 120 mm and are available in various shapes, such as rounded or flat ends, as well as with different finishes, including flared, rolled‑edge, and frosted surfaces. They offer excellent resistance to high temperatures and corrosion, superior light transmission, and are moisture‑proof and explosion‑proof. These products are widely used in applications like aquarium lighting, disinfection equipment, heating elements, and water treatment, as well as in environmental protection, hygiene, and the chemical industries. Quartz water jackets are particularly prevalent in the printing and packaging industries, where they support UV curing—a highly reliable curing process that can replace conventional hot‑air dryers and other drying technologies—and has already gained widespread adoption in these sectors.
