2. Applicable Equipment
Suitable for high-temperature valves, high-pressure pumps, boiler equipment, steam pipelines, heat exchangers and high-temperature reaction vessels. Especially recommended for static sealing and high temperature valve applications.
3. Applicable Industries
Widely used in thermal power, petrochemical, metallurgy, boiler manufacturing, nuclear power and other high-temperature industrial fields.
4. Compatible Media
Adaptable to high-temperature steam, superheated water, heat transfer oil, high-temperature gas, acid and alkali media within certain concentration range. Not suitable for strong oxidizing media.
5. Typical Working Conditions
Ideal for high-temperature and high-pressure valve sealing, boiler manholes, heat exchanger gaskets, furnace door seals and other high-temperature static sealing applications, as well as high temperature pump and agitator seals.
This packing is suitable for sealing pumps and valves working in steam, water, solvent, acid and alkali environment, and is not recommended for strong oxygen mediums. When applied to the seals of pumps and valves, it can be used alone or as a combination of end rings and graphite molded rings.
