Product Description
Embedded Fin Tube G Type is made with the fin strip wounded into a machined groove and securely locked into place by back filling with base tube material. This technique ensures maximum heat transfer and a temperature of working until 450C°.The fin strip is wound into a machined groove and securely locked into place by back filling with base tube material. This ensures that maximum heat transfer is maintained at high tube metal temperatures.
G Finned Tube Manufacturing Process
A helical groove is formed in base tube displacing of material and fin is wound into the groove under tension, followed by backfilling of the displaced material to lock the fin root into the tube.
