HAIRPIN HEAT EXCHANGERS

ADVANTAGES

  • Operates in true counter current flow permitting extreme temperature cross.

  • Economically adaptable to service differentials.

  • Ideal for wide temperature ranges and differentials.

  • Standard double pipe or multi-tube design reduces engineering, thermal design,
    drafting and shop fabrication costs.

  • Provides shorter deliveries than shell and tube due to standardization of design and construction.

  • Resistance welded longitudinal fintubes utilized for high heat transfer efficiency.

  • Available in a wide range of sizes to meet most process requirements.

  • Multiple sections shipped completely assembled and ready for process piping connection.

  • Can custom engineer equipment to meet any process or piping requirement.

  • All hairpin heat exchangers are A.S.M.E. inspected and Code stamped.

   

The Holland Petrofin Patented Closure

  • The most efficient seal on the market.

  • Guaranteed against interstream leakage.

  • Allows for more tubes in a given shell size
    resulting in more heat exchanger for the same competitive dollar.

   

The Holland Petrofin Patented Closure

  • Contains separate flanges and bolting for each
    sealing surface.

  • Can handle all applications in severe service.

  • Recommended for pressures above 2000 psig,
    cyclic service, low temperature service, extreme temperature differentials and hard to hold fluids.
