99.95% Polished High Precisely Custom production Factory direct sales of hard tungsten tube, molybdenum tube

Tungsten pipes are mainly used for thermocouple protection tubes in high temperature furnaces, supports in sapphire single crystal furnaces and high temperature sintering furnaces.
Tungsten alloy has a good radiation shielding effect, so tungsten alloy tubes can be used in medical shielding needle tubes; The engine used in rocket propulsion is a jet engine that uses compressed high-performance fuel. The temperature generated during rocket launch can reach thousands of degrees. Tungsten alloy tube is a metal material with high temperature resistance, so it is used in the lining and ignition tube parts of rocket engines. The ignition tube is deep into the combustion chamber of the engine, and generates huge heat immediately after ignition. At this time, the ignition tube must withstand thousands of temperatures, which requires high temperature resistance of materials.
