Graphite Tubes and Rods
Inquiry NowProduct Description
General Description:
Material: Graphite is a form of carbon with a unique atomic arrangement that imparts it with exceptional properties. Graphite tubes and rods are primarily composed of high-purity graphite, which is typically derived from natural graphite or synthetic graphite. High-purity graphite ensures excellent thermal and electrical conductivity.
Graphite is known for its high thermal conductivity, low coefficient of thermal expansion, chemical inertness, and lubricating properties. Graphite tubes and rods find applications in various industries, including metallurgy, chemicals, electronics, and aerospace.
Manufacturing Process: Graphite tubes and rods are usually manufactured through a process called extrusion or isostatic pressing.
- Extrusion: In this process, graphite powder mixed with binders is forced through a die to form the desired shape. The extruded shape is then heated to remove the binders and achieve the final graphite structure.
- Isostatic pressing: Isostatic pressing involves subjecting graphite powder to high pressure in a flexible mold using fluids. This compresses the powder to form a solid structure that is then further processed to obtain the desired tube or rod shape.
Dimensions: Graphite tubes are hollow cylindrical structures with varying inner and outer diameters, wall thicknesses, and lengths. Graphite rods, on the other hand, are solid cylindrical structures with uniform diameters and lengths. The dimensions of graphite tubes and rods can be customized according to specific requirements.
Graphite tubes and rods can be customized with features like threaded ends, flanges, or other connectors to facilitate installation and connections in specific applications.
It’s important to note that the specific properties and dimensions of graphite tubes and rods can vary based on the manufacturer and the intended application. Therefore, it’s advisable to consult the M-Kube team for detailed specifications and recommendations based on your specific needs.
