Non-Sag Pure Tungsten Tube

Tungsten tube is mainly used in thermocouple protection tube in high temperature furnace, sapphire single crystal furnace and support in high temperature sintering furnace. Tungsten has a good radiation shielding effect, so tungsten tube can be used in medical shielding needle tube; used in rocket thruster, the engine is a jet engine, which uses high-performance compressed fuel, and the temperature generated during rocket launch can reach thousands of degrees.

Tungsten tube is a metal material with high temperature resistance, so it is widely used in rocket engine It is used in lining and ignition tube parts. When the ignition tube is deep into the combustion chamber of the engine, huge heat is generated immediately after ignition. At this time, the ignition tube has to bear thousands of temperatures, which requires high temperature resistance of materials.
