Definitions

  • the metallic jacket acts as an intermediate layer, which avoids welding between the steel cooling pipe and the cast iron body, and which can absorb strains and stresses.
  • the metallic jacket is in tight contact with both the steel pipe and the cast iron body. This is extremely advantageous with regard to heat transfer, since copper, nickel and their alloys have a high thermal conductivity. The tight contact between the different materials and the high thermal conductivity of the metallic jacket ensure an intensive heat transfer from the cast iron body to the cooling pipe.
