Tips on the maintenance of graphite equipment: Standards for the integrity of graphite equipment: the equipment passes the pressure test and air tightness test, is anti-corrosion as required, and has complete and intact parts and components; the equipment is clean and intact, with no leaks, leaks, or leaks. Since graphite material is a brittle material with low impact strength, protection should be strengthened during transportation and loading, and unloading. It is strictly prohibited to knock, avoid collisions, and avoid direct stress on graphite parts. Graphite parts must not be pried with pry bars or directly tied with wire ropes. Protective measures must be taken for graphite components exposed outside the metal shell.
When the operating temperature is high, the sealing performance may be affected by thermal deformation of the sealing gasket. Therefore, new equipment should be checked for leaks after a few hours of initial use. If there is leakage, the corresponding bolts can be tightened appropriately first, and then other bolts on the flange can be tightened appropriately to achieve the sealing effect. If the material contains debris, a pipeline filter should be installed in front of the inlet pipe to prevent blockage from affecting the heat transfer. If the equipment is severely fouled, appropriate chemical methods can be used to clean it; if it is blocked by crystals, it can be heated and melted for cleaning. Because graphite is a brittle material, mechanical treatment should be avoided. When using chemical cleaning methods, it should be ensured that they cannot react with graphite materials and adhesives. Valves should be installed at the high-point venting and low-point draining positions of the shell, and blind plates should not be used to block them. To avoid frequent starts and stops of graphite equipment to extend the service life of the equipment, the extended graphite pipes of the graphite equipment are strictly prohibited from receiving radial force during installation. If the original equipment is not equipped with a steel protective sleeve, you must make your own equipment to enhance the protection of the graphite accessories.
