Tungsten tube

Tungsten tube is a kind of tube made of tungsten as the main material, which usually has the characteristics of high strength, high hardness, high melting point and good corrosion resistance.

Classification:


  • Material characteristics

    1, tungsten tube has a very high purity, the general purity of more than 99.95%.

    2. Its density is above 18.2g/cm³.

    The working temperature of the recommend should be lower than 2500 ℃.

    At high temperatures, the thermal expansion coefficient and thermal stability of the tungsten tube are excellent.

    The tungsten tube has low pollution and is suitable for use in environments that require high purity.

    Product use

    ▲ Tungsten pipes are mainly used in thermocouple protection tubes in high temperature furnaces, sapphire single crystal furnaces, supports in high temperature sintering furnaces, etc.

    ▲ Tungsten alloy has good radiation shielding effect, so tungsten alloy tube can be used for shielding needle tube in medical treatment. The engine used in rocket propellers is a jet engine that uses compressed high-performance fuel, and the temperature generated during rocket launch can reach thousands of degrees. Tungsten alloy tube is a metal material with extremely high temperature resistance, so it is used in the lining part and ignition tube parts of rocket engines. The ignition tube is deep into the combustion chamber of the engine, and huge heat is generated instantly after ignition. At this time, the ignition tube has to withstand thousands of temperatures, which requires high temperature resistance of the material.
