Gaps often occur in the process of making fused quartz spiral / helical tubes by hand. That’s because the heating is not in place. So once the temperature is too high, the spiral tube will be deformed. After years of process improvement, our company has been able to well control the gap of quartz spiral. Whatever big or small size of spiral tube, we all can make it. Welcome to contact us.

Clear fused quartz tubing is a high purity (99.99%+) quartz glass suitable for temperatures up to 1300 C.  Resistance to thermal shock is another important property of quartz tubing. Email us for pricing on custom cut lengths and/or spliced or fire polished tubes.

Fused Quartz Glass Features:

Clear Fused Quartz Tubing has all the excellent properties of quartz glass. This is the main materials of the production of actericidal lamp shell, deep processing to various of lab glassware & instruments and furnace tubes.

1, Incredibly thermally shock resistant (can be taken from red heat and plunged into water without cracking).
2, Low thernal coefficient of expansion (TCE) and high softening temperature.
3, Optical transmission properties from ultra violet to infra-red.
4, Good chemical resistance.
5, Excellent electrical insulator.
