Product Description

 

Product Description

 

We use our advanced ceramic materials to make extruded ceramic rods and extruded ceramic tubes, primarily for use in temperature measurement equipment for the Oil and Gas Industry and other industrial heating applications. They are also used in some specialist Aerospace applications.

 

Single Bore alumina tubes, 95%-99.7% purity, and 10-2500mm in length with a single bore all the way through.

Twin Bore, Four Bore, And Multi Bore

Closed One End alumina tubes, 95% 99.7% purity and 50-2500mm meter in length with an open end and a closed-off rounded end.

Regular dimension:
 

1. Outer diameter:3mm-25mm;
2. Maximum length 2500mm;
3. Thickness: by dimension scale of product 0.5mm to 4mm.
