Gray Quartz Glass Tubes

These Gray Quartz Glass Tubes are the good material for electric heating and far-infrared heating. It has been enjoying high reputation since it came out. On the basis of sustaining innovation and rich experience, its quality has entered the best line of this field in China, even in Asian market. Low price with high quality, excellent service is also provided here.

Capability and Purpose of Quartz Glass
Quartz glass is special industrial technology glass made by silicon dioxide and is one kind of excellent basal material.Quartz glass has series of excellent physical capabilities.For example:
1.Heating resisting. The softening point of quartz glass is 1730 degree,it can be used long under 1100 degree.And the highest using temperature can get up to 1450 degree in very short time.
2.Corrosion resisting. Quartz glass can not react with other acid material except hydrofluoric acid.Its acid resisting ability is 30 times of ceramic,and 150 times of stainless steel.Especially for its chemical stability under high temperature is better than any other projected material.
3.Heat stability is better. The coefficient of expansion is very small.It can bear exquisite changing temperature .Heat up quartz glass to 1100 degree,then put into normal temperature water and it will not broken.
4.Capability of previous to light better. Quartz glass has better previous capability in the whole spectral wave band from ultraviolet radiation to infrared.
