The jacketed vessel fabricated on site aids in regulating temperatures and minimizes heat loss or heat gain which decreases maintenance costs. Along with regulating temperature, jacketed vessels can maintain and control the quality of your product. Depending on use, there are many types of jacketed vessels.


  • contain a second shell over the vessel
  • creates an annular space that allows for cooling or heating medium to flow through
  • best used for low pressure applications (<50 psig)
  • commonly used with high volume fluids
  • has a low price point for smaller vessels ( usually used for <100 gallons)

Half-Pipe Coil

  • welded around the vessel
  • best for when jacket pressure is used to determine wall thickness
  • middle of the road cost
  • Pressure good up to 500 psig
  • Used commonly for steam, water, hot oil, and other media


  • Contains a thin shell around the vessel by way of spot welds
  • The dimples impact the heating or cooling media that moves through the jacket
  • Very adaptable
  • Higher pressure than conventional (up to 200 psi)
  • Have a lower price point for larger vessels
  • Best at 300F or less

Internal Coil

  • Often used in industrial and chemical application
  • Provides high flow
  • High pressure (up to 900 psig)
  • High pipe ratings

Discover the Attributes and Best Uses of Heat Transfer Surfaces

Thermal heat exchange surfaces are utilized on vessels for controlling temperature and quality of the contents of the vessel. Heat exchange surfaces can be designed for heating or cooling.
