Selection criteria for heat exchanger gaskets
Thread Content
May I ask what the difference is between wave-shaped gasket pads and graphite composite gaskets? Are they the same thing? Are the graphite composite gaskets used in heat exchangers the same as wound gaskets? What does G54 mean in G54-1200-5.0-6 JB/T4718?
In G54-1200-5.0-6 JB/T4718, G54 means: G54 = gasket name code + metal material code + filler code; G represents the tube box, 5 indicates that the metal material is 0Cr19Ni9, and 4 refers to flexible graphite. Therefore, the meaning of G54-1200-5.0-6 JB/T4718 is: DN1200mm, PN5.0MPa, 6 tube passes; the material used is 0Cr19Ni9, the gasket is a tubular box gasket made of flexible graphite, and the manufacturing standard is JB/T4718.
They are not the same; moreover, the standards have been updated, so it’s not a replacement relationship.
Comparison of prices for flexible graphite wave-shaped gaskets, metal gaskets, and graphite wound gaskets – which option is the most cost-effective?
