Application
Tungsten tube is widely used in the thermocouple protection tube, sapphire crystal furnace and high temperature furnace, etc. Tungsten is usually sintered processed and with 8mm wall thickness. Tungsten pipe contributes stability to the hot zone. While high in thermal inertia, tungsten tube may prolong the growth cycle of the sapphire. The maximum wall thickness of one that rolled from tungsten plate is 2mm with low thermal inertia. But they are not as reliable and durable as normal ones.
Features
1. The surface of tungsten tube is silver gray metallic luster.
2. The purity of tungsten pipe is no less than 99.95%.
3. Its density is more than or equals to 18.8g/cm3.
4. The production processes include isostatic pressing, IF induction sintering, CNC vertical turning, CNC milling, coreless grinder and wire cutting.
5. The tungsten tubes we produced are with high-precision, finish surface, straight size, and high temperature deformation.
6. There are two kinds of tungsten pipes: one is with diameter 8--70 mm, wall thickness more than 3mm, maximum length 300mm and density no less than 18.8g/cm3. Another one is with diameter 70—500mm, wall thickness more than 8mm, maximum length 700mm and density no less than 18.3g/cm3.
Package and Inspection
We offer material composition sheet and examination report which include density, flaw detection, dimensions and so on. Our products are packed in plywood case with expanded plastic. What's more, the case is moistureproof and grooved for tungsten tubes being fix placed.
Achemetal Furnace Co., Ltd. is a professional China tungsten pipe manufacturer. We forge tungsten, molybdenum, TZM and Mo-La alloys in rods, bars and blocks. Using high purity material, we also output tungsten and molybdenum electrodes for welding or glass melting, tungsten and molybdenum tubes, tungsten and TZM Bars and other products with high density and excellent mach inability. Above 60% of our tungsten tubes are exported to more than ten countries and areas, such as USA, Germany, Japan, Russia, South Korea, etc.
