Half-Pipe Coil Heat Transfer Surface

Half-pipe coil is best suited for high-pressure fluid heat transfer applications. Half-pipe coil comes in a fully-welded assembly, fit and tacked, or loose coils depending on your tank fabrication process. Our layout technicians can also produce drawings detailing the number of turns necessary for your heat transfer surface.

Defining Features

  • Handles large flow volumes effectively
  • Great for cyclic heat transfer conditions


  • Configurable for tank heads, shells, and cones
  • Low pressure drop
  • Highest heat transfer surface pressure rating out of all available heat transfer types
