Видове и употреби на тръби от молибден и волфрамови тръби
The molybdenum tube has good high temperature resistance, and can be used continuously for more than 4,000 hours in a vacuum environment at 1800 degrees. Molybdenum tubes are widely used in the electric vacuum industry, and can be used as heating tubes, high-temperature environment cooling tubes, high-temperature environment protection tubes, etc. Large molybdenum tubes can be used as ring targets, furnaces, etc., and small molybdenum tube instrument spare parts.
The types and processing methods of molybdenum tubes are: deep hole drilled molybdenum tubes, sintered molybdenum tubes, welded molybdenum tubes, molybdenum coiled tubes, drawn molybdenum tubes. Sintered molybdenum tubes are used to produce large molybdenum tubes, mainly used in smelting equipment, furnace tubes, annular targets, vacuum heating chambers, etc. The largest size can be 1200mm in diameter; welded molybdenum tubes are used for equipment parts that are not strictly required in size. The most important thing is vacuum welding, and the size should not be too large, with a diameter of 8-500mm; the production process of drawing molybdenum tubes is complicated, and it is used to produce small molybdenum tubes, with a diameter of 1.0-6mm.
Molybdenum tubes can be used as tungsten-rhenium thermocouple protection sleeves, grids and cathode support tubes for high-power electronic tubes, sputtering targets, etc.
Molybdenum tube material: high-purity molybdenum/high temperature molybdenum
Molybdenum tube classification: sintered molybdenum tube, forged molybdenum tube
Molybdenum tube application: thermocouple protection tube, heat insulation tube, sintered tube, protective sleeve, etc.
Tungsten tube, that is, pure tungsten tube, is one of the main pure tungsten products. The purity of the tungsten tube produced by Zhuohangxin Metal can reach more than 99.95%. Due to the difference in the production process, the density will be different. If the product is only sintered, the density can reach 18.2g/cm3, and if it is completely forged, it can reach 19.2g/cm3. However, if the size is large, such as 100mm in diameter, even after forging, it cannot reach 19.2g/cm3, and the attainable density is about 18.8g/cm3. Pure tungsten tube has a high density, so it is a good material for shielding. At the same time, due to the characteristics of pure tungsten itself, high melting point, high boiling point, high temperature resistance, corrosion resistance, and low thermal expansion coefficient, tungsten tubes can be used in pipelines for corrosive liquids and low melting point metals.
