First, the application of graphite packing sealing filler: 1, graphite packing sealing packing is especially suitable for various devices under high temperature and high pressure harsh environment. 2. Graphite packing packing is applied to other mediums except strong acid, strong alkali and strong oxidant. 3, graphite packing sealing packing is especially suitable for working conditions under higher temperature and high pressure conditions. 4, graphite packing sealing packing has a long service life, greatly improving work efficiency and reducing downtime maintenance time.
Second, the use of graphite packing seal filler: graphite packing seal filler can be used to seal hot water, high temperature, high pressure steam, heat exchange medium, hydrogen, ammonia, organic solvent, hydrocarbons except a few strong oxidizing medium , low temperature liquid and other media, graphite packing seal fillers are used in the sealing of valves in petroleum, power plants, chemical, steel and other industrial fields.
Third, the graphite packing seal filler preparation: 1. Remove the old seal filler Check the stuffing box is the key to the preparation of the pre-installed seal filler. 2. Before using the sealing packing, remove all the old sealing packing with special tools and wipe the packing box clean. 3. Observe the damage and eccentricity of each part of the stuffing box. The damaged valve stem, bushing and stuffing box can affect the performance of the graphite packing packing. 4. Check if other parts are still applicable and replace all damaged parts. 5. Adjust whether the bearings are concentric, such as disagreement, need to be adjusted or replaced. 6. Check if the pump or the stirred tank is vibrating and adjust to a smooth running state.
4. Overview of Graphite Packing Sealing Packing: Graphite packing packing has many subdivided products, such as: expanded graphite packing packing; flexible graphite packing packing; nickel wire graphite packing packing; stainless steel wire packing Sealing packing; high temperature resistant graphite packing packing; high temperature and high pressure graphite packing packing; graphite packing sealing material is mainly made of various reinforcing fibers, wire (steel wire, copper wire, nickel wire) and other graphite wire The raw materials are woven by precision. Graphite packing seals are suitable for static sealing under high temperature and pressure conditions. In addition to a few strong oxidants, it can be used to seal hot water, seal hot steam, seal heat transfer fluids, seal ammonia solutions, seal hydrocarbons, seal low temperature liquids and other media. Graphite packing packing is also a unique universal sealing packing.
