Graphite is a material that can be used in grounding systems because of its high thermal and electrical conductivity. It can be utilized as a grounding plug or plate, or even to upgrade existing grounding electrodes. SSOE offers engineering, procurement, and construction (EPC), services that integrate the latest technology in the industry to achieve optimal performance.
SSOE collaborated with a chemical customer to provide EPC Services for the Installation of a New Graphite Electrode Manufacturing Facility. The scope included construction and equipment foundations as well as the installation of a conveyor system and graphite-electrode furnace. The client's process is to create graphite electrodes that serve the steel industry.
Graphitizing is the process by which coal is converted into graphite under pressure and heat. To prevent carbon materials from being oxidized, the process is usually carried out under a reducing or inert atmosphere. The graphite then is impregnated and baked with pitch binder to ensure that the material has excellent electrical conductivity.
After initial production, the graphite electrodes are put through several mechanical tests to test their resistance to physical stress in operation and handling. These tests can help determine whether electrodes will be able to resist bending or impact forces. They can also be used to measure the quality of threading that is essential for nipple connectors.
After the graphite was impregnated with a solvent and baked, the electrodes were further baked to reduce their porosity. This allows the electrodes to withstand high temperatures and extreme stress. The electrodes are also further solidified and oxidation is reduced.
To install a carbon electrode, you must place it into its holder. Make sure that the holder is not in the alarm zone. It is important to clean the holder regularly in order to maintain a good connection with the electrode. If the holder has not been placed correctly, the electrode could rupture or even break. In order to avoid such a situation, it's important that you follow the instructions included in the holder user manual. When installing, use a torque-wrench to tighten and not overtighten your screws. Wearing gloves during the installation will protect your hands against the friction caused by the screw. Be sure to avoid touching the electrode directly with your skin. If you touch the electrode, it can cause blisters. If you are unable to use gloves, it is recommended that you wear protective eyewear. This will protect your eyes from spitting particles of molten graphite, as well as other contaminants that can be present during the installation process. After the installation, check the electrode and holder to make sure they are in good working order. It is important to replace your electrode if it shows signs of wear and tear or any damage.
