Item Feature: The FIRST manufacturer has been producing Opaque
Quartz Glass Tube in China It has no any harmful radiation, and it
is characterized by high temperature resistance, good thermal
stability, free selection of heating temperature, and no change in
radioactivity for long terms of use, long service life, reasonable
structure, convenience in use and less thermal inertia, etc. Also,
they have some functions of transparent quartz glass tubes.
Furthermore, they are used as their far-infrared reflection
materials.
Applications: It serves as material of infrared heating for
heaters, micro-wave oven, electrical baking over, sterilization
container and other consumptive and industrial infrared
application.

3.Detailed Specifications and Technology Standards
The Out-diameter deviation of the Opaque quartz glass tube should not be over the stipulations in Table 1
Range of Out-Diameter | 8≤≤16 | 17≤≤25 | 26≤≤35 | 35 |
Out-Diameter Deviation | 0.30 | 0.50 | 0.70 | 1.00 |
Note: 1. the tubes, with both end open and one end open, are available. The Out-diameter of the dome end, if so, should not be over the Out-diameter of the tube. 2. For the tubes with special dimensions, it needs to be discussed by the both sides of supplier and customer. |
