Tex-Fin | Finned Tubes


  • Helical serrated fin pipes are used in heat recovery equipment such as economizers and chillers to process heated liquids for specialty applications.
  • Common applications include recovery operations associated with boilers, gas turbines used in power generation and furnaces used in petrochemical processing and refining.
  • High frequency serrated pipes are manufactured helically forming a segmented metal strip around a pipe.
  • The strip is welded to the pipe using high frequency electrical resistance welding (HFRW) during the forming process.
  • The segment metal strip produces non-parallel fins.
  • HFRW is faster than GMAW welding, produces a more consistent weld, allows us to weld similar and dissimilar metals and reduces the need for heat treating the finished product.
  • It provides a homogenous, clean, continuous bond between the metal strip used for the fins and the pipe.

Tex Fin’s helical finned pipes are custom manufactured to your exact specifications to meet the demands of your applications.   We offer the following options:

  • Pipe materials available are carbon steel, carbon moly, stainless steel, Incoloy ®and Inconel®. Other alloys are available if needed.
  • Fin materials available are carbon steel, 304, 316, 321 and 409 stainless steels. Other alloys are available if needed.
  • Pipe sizes from 1” O.D. to 8 NPS (8.625” O.D.)
  • Fin heights from 3/8” to 1-1/2”
  • Fin thickness from 20 ga. (.035”) to 14 ga. (.075”)
  • Fin pitch from 1 fins/in. to 7 fins/in.
  • Fin pitch from 3/4 fins/in. to 7 fins/in.
    • Pipes can be bent into the shapes required for your application.
