| Clear Fused Quartz Glass Tube |
This is clear
fused quartz glass tube available as continuous machine drawn
and automatic controlled tubing .this glass has the typical
characteriastics of high purity ,good spectral transmission,weellcontrolled
dimension and lower OH and so on .it serves as the first choice
of heat resistant material for halogen lamps ,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 1200-1500mm length. Exhaust tube with good CPK
are suiable for highspeed streamline production .and further
processing of trim cutting ,fire polishing ,bending and pinchingcan
be done according to the requirement of cusomers .OH-content
can be controlled within 20ppm/15ppm/10ppm/5ppm/2ppm according
to the requirement of customers.
The detailed dimensional tolerance and technical data can be
found in table I，table II,table III, tableIV, tableV.
