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.
