The application of expanded graphite filler and sealing material is very effective in examples, especially suitable for sealing under high temperature and pressure conditions and sealing through toxic and corrosive substances. Both the technical superiority and the economic effect are very obvious. The following Furuite graphite editor introduces you:
Expanded graphite packing can be applied to all kinds of valves and surface seals of main steam system of 100,000 kW generator set in thermal power plant. The working temperature of steam is 530℃, and there is still no leakage phenomenon after one year’s use, and the valve stem is flexible and labor-saving. Compared with asbestos filler, its service life is doubled, maintenance times are reduced, and labor and materials are saved. Expanded graphite packing is applied to the pipeline conveying steam, helium, hydrogen, gasoline, gas, wax oil, kerosene, crude oil and heavy oil in an oil refinery, with a total of 370 valves, all of which are expanded graphite packing. The working temperature is 600 degrees, and it can be used for a long time without leaking.
It is understood that expanded graphite filler has also been used in a paint factory, where the shaft end of the reaction kettle for producing alkyd varnish is sealed. The working medium is dimethyl vapor, the working temperature is 240 degrees, and the working shaft speed is 90r/min. It has been used for more than one year without leakage, and the sealing effect is very good. When asbestos filler is used, it has to be replaced-times every month. After using expanded graphite filler, it saves time, labor and materials.
