Tungsten Tubes

Tungsten Tubes

Description:
Made from high purity tungsten, tungsten tube is widely used in the thermocouple protection tube, sapphire crystal furnace and high temperature furnace, etc.

Features:
1. Tungsten tube is of fairly high purity above 99.95%;
2. Its density is above 18.2g/cm3;
3. The recommended working temperature should be below 2500℃;
4. The blackness of tungsten tube at 2027℃ is 0.2965;
5. Its thermal expansion coefficient at 1600℃ is 4.98x10-6;
6. The specific heat capacity at 1400℃ is 0.16J/g.℃.
7. It causes low pollution.

Parameters of Tungsten Tubes:
1. The diameter of tungsten tube ranges from Φ100 to Φ500. Its tolerance and ellipse is within 0.5mm;
2. Single maximum height of tungsten tube can be reach 800mm. Tubes can joint together to meet the specific needs;
3. The roughness of surface finish is Ra1.6mm.

Packing and Shipping:
We deliver pure tungsten tubes in plywood cases by ocean shipping or air transportation.

Notice:
1. Due to the heavy and fragile properties, tungsten tubes should be lifted slowly and steadily by high strength hoisting soft belt;
2. The relative humidity of the working environment should be no more than 60%; otherwise tungsten tubes are easily catch oxidation;
3. During the installation, the support structure and foundation of tungsten tubes should be level and firm at both normal and high temperature to ensure a steady working environment.
