Product Description

Specification

This quartz heating tube has the typical characteristics of high purity, good spectral transmission, well controlled dimension and lower OH and so on. It serves as the first choice of heat resistant material for halogenlamps, mercury lamps, metal halide lamps and other quartz lamps. This glass can be supplied in the range of 3-80mm outside diameter, 0.6-2.0mm wall thickness and 800-2400mm length. Exhaust tubes with good CPK are suitable for high-speed streamline production. And further prcessing of trim cutting, fire polishing, bending and pinching can be done according to the requirement of customers. OH-content can be controlled within20ppm\\15ppm\\5ppm\\2ppm according to the requirement of customers.

We produce different sizes and kinds of quartz tubes, such as thick wall quartz tubes, large diameter quartz tube, quartz twin tube, u-shape tube, C shape tube, quartz capillary tube, perforated tube, four holes tube, one end closed tube, quartz test tube, heat resisting quartz tube, corrosion resisting quartz tube, and other special shaped tubes according to customers' design.
