Project Description

Air Inlets Reverse Circulation Well and Foundation Drilling

  • The Holte Air Inlet is made of a low carbon alloy steel and carburized to file hard prox 62 Rockwell.
  • Long lasting, smooth, hard surface for rotating seal.
  • One ring nut on each end provides even pressure to the packing.
  • A lantern ring in the center of each packing distributes lubricant  evenly.
