Clear Surface Quartz Tube Vacuum Flange 80% Large UV Transmittance

Product description:

Fused clear silica quartz glass flange is made of high purity quartz sand with excellent thermal shock stability and high transmittance.

It is widely used in electric light/ laser/ lenses/optical instrument/high temperature window.

The deep processing would be done according to client's requirements, like neat cutting, punching,finish milling, fire polish, welding, bending, sealing, polished and so on. We have rich experience in quartz flange welding to make sure the welding products dimensions.

Over the years,the company constantly introduce high-precision processing equipment,like CNC / Laser equipment / glass milling and grinding machine to insure the accuracy of the products.

Product selling point:

① High Temperature Resistance:

The hardening point temperature of quartz glass is about 1730℃, and it can be used for a long time at 1100℃, with the temperature up to 1450℃.

② corrosion resistance:
Except for hydrofluoric acid, quartz glass does not react with other acid substances. Its acid resistance is 30 times that of ceramics and 150 times that of stainless steel, especially its chemical stability at low temperature, which cannot be compared with other engineering materials.

③ Good Thermal Stability:
Quartz glass has a small thermal shrinkage coefficient and can withstand drastic temperature changes. Quartz glass can be heated to 1100℃ or so without bursting when it is put into normal temperature water.

④Good pervious to light:
Quartz glass has good transmittance in the spectral band from violet inner line to red inner line, the visible light transmittance is more than 93%, and the transmittance in ultraviolet spectrum is more than 80%.

⑤Good electrical insulation:
Quartz glass resistance value commensurate with ordinary glass ten thousand times, is a good electrical insulation material, even at low temperature has good electrical properties.
