ASTM A179 Carbon Steel Tube With Aluminum1060 Fins, Embedded G Type Fin Tube
What is Embedded Fin?
Embedded “G Type” Fin tube 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 G Type Fin Tube is known as Embedded Fin Tube. This type of fin tubes is widely used in the rapplications of higher operating temperature and relatively lower corrosive atmosphere Fins are manufactured by embedding the fin stripS into a groove formed on the base tube. Fins are allowed to be placed in the groove and then the back filling of the groove is carried out to ensure firm adherence of the fins to the base tube. Due to this process, this type of Fin Tubes is also known as ‘G’ Fin tube or Grooved Fin Tube.
Advantages:
High fin stability
Excellent heat transfer
High operating temperature
