RBT–non-metallic fiber reinforced flexible graphite braided filler
\nRBTN–Internal non-metallic and metal-reinforced flexible graphite woven filler
\nRBTW – External Metal Reinforced Flexible Graphite Woven Filler
\nRBTH–Flexible Graphite Woven Filler Moulding Ring<\/p>\n

Usage<\/h4>\n

Can be used for boiling water, high temperature, high pressure steam, heat exchange liquid, oil, acid and alkali, hydrogen, ammonia, organic solvents, hydrocarbons, cryogenic liquids and other media. Widely used in petroleum, chemical, electric power, metallurgy, machinery, paper and other industries of centrifugal and reciprocating pumps, valves, pipes and other seals. <\/p>\n

Transportation and Storage<\/h4>\n

Prevent rain and moisture during transportation.
\nShould be stored in a clean, dry warehouse. <\/p>\n

The sealing principle<\/h4>\n

The reason why woven packing can play a role in sealing is mainly the bearing effect and the labyrinth effect.
\nThe bearing effect of braided packing means that a layer of liquid film is formed between the braided packing and the shaft due to the tension, so that the braided packing and the shaft form a similar relationship to the sliding bearing so that the braided packing and the shaft are not excessively rubbed. And wear occurs.
\nThe labyrinth effect of braided packing means that the surface of the shaft is virtually always uneven, and the packing and the shaft can only partially fit and do not completely fit together. There is always an extreme between the braided packing and the shaft. With tiny gaps, these gaps form labyrinth belts in which the medium is throttled several times to achieve sealing. <\/p>\n
