1.Product description:

Quartz Glass Tube is made of silicon dioxide in special industrial technology glass,is a very good base material.

Quartz glass has a series of excellent physical and chemical properties.Quartz glass tube adopts advanced melting

production technology, combined with effective automatic control system for producing transparent quartz glass tube, with high purity, strong transmissivity, size control strictly, hydrowyl coneten is low, is halgen lamp, mercury lamp,

 metal halide lamp and other high temperature resistant materialof choice for quartz lamp, the exhaust pipe has the characteristicsof pipe diameter, wall thickness, high consistency, and suitable for quick assembly line production.Also can according to customer requirements to neat cutting of quartz tube, buring mouth, bend sealing, grinding, such as deep processing.
