Custom Fabrication Quartz Glass Spiral Tubes in Various Special Shapes 2

We specialize in custom fabrication of quartz glass spiral tubes in various special shapes, delivering precision solutions for demanding industries. Using high-purity quartz glass, we produce helical tubes with excellent thermal stability, chemical resistance, and optical clarity. Custom options include spiral diameter, tube diameter, wall thickness, pitch, length, bend angle, and end configurations. We support OEM and ODM projects, prototypes, and low-to-high volume production. Applications include semiconductor equipment, laboratory systems, heating elements, chemical processing, lighting, and analytical instruments. Our advanced forming, annealing, and cleaning processes ensure reliable performance under high temperatures and harsh environments. Strict dimensional inspection and surface quality control are applied to every order. Send us your drawings, samples, or specifications, and our engineering team will provide a tailored quotation and production solution. Whether you need irregular shapes, tight tolerances, or complex spiral designs, we deliver custom quartz glass spiral tubes with consistent quality and fast global turnaround.

Fused Quartz Glass Features:

Fused quartz glass is a special industrial glass made of silicon dioxide. It is a very good basic material. Quartz glass has a series of excellent physical and chemical properties.

1. High temperature resistance. The softening point of fused quartz glass is about 1730℃ and can be used for long time working under 1100℃~1250℃.  And working at 1450℃ in a short time.

2. Corrosion resistance. In addition to hydrofluoric acid, fused quartz glass is inert to other acids. Its acid resistance is 30 times as ceramic, 150 times as stainless steel. Especially, any other material cannot make a comparison with chemical stability of fused quartz at high temperature

3. The thermal stability is good. Thermal expansion coefficient is extremely small. And it can withstand severe temperature changes such that heating up to 1100℃ and putting it in normal temperature water will not crack.

4. The light transmittance is good. Quartz glass has good transmittance in the whole spectral band from ultraviolet to infrared. The transmittance of the visible light is above 95%. Especially in the ultraviolet spectrum band and the maximum transmittance is over 85%.

5. The electrical insulation performance is good. Resistance value of quartz glass equaling to 10000 times of ordinary glass. It is an excellent electrical insulating material and has good electrical properties even under high temperature.

As a leading China fused quartz glass supplier and manufacturer, we are providing best price as well as quality for all kinds of customized fused quartz products. We are also willing to look for long term partners who are a distributor or wholesaler specialized in fused quartz glass in local.
