Overview
Product Details
Graphite Tube
Our graphite tube is made of good performance graphite blocks. We have molded graphite , high pure graphite ,fine-grain graphite, medium-grain graphite and so on. They are widely used in metallurgy, machinery, electronics and chemical industry, etc.
We can choose suitable graphite materials to make graphite tubes according to your requirements or working conditions.
Advantage:
1.Reduce the consumption and lower down cost
2. Perfect sealing performance. long service life, low maintenance.
3. Stable performance and durability
4. Good thermal conductivity,
5. Low coefficient of thermal expansion
6. Excellent corrosion resistance: The product uses high-quality graphite carbon material and adds organic compound with strong acid resistance, which effectively reduces the porosity of the product and improves the volume density of the product.
Application:
1.Used in furnaces because of graphite's low heat sensitivity
2.Used for Aluminum degassing
3.Used in the production of fluxing tubes used in the metal manufacturing industry
4.Other industries using graphite tubes include chemical and scientific industry
