G Type Embedded Fin Tube Suppliers in China
G Type Embedded Finned Tube is that the fin strip is tension wound and placed in the groove cut into the tube with appr,0.35-0.5mm groove depth,then the bottom of the fin is guided into the groove and backfilled with base tube Firmly, finally lock the fins in place by rolling the grooves enclosed in the bottom of the fins.In order to prevent the steel strip from rebounding and falling off,the two ends of the steel strip should be welded to the steel tube.
Quality Control for G Type Embedded Finned Tube
The quality of the G type embedded fin tube is assured by hydrostatic or pneumatic testing, eddy current testing and tensile testing to verify the mechanical bond between the inner tube and the outer fins.

What is the Difference Between Embedded Fin Tubes and Wound Fin Tubes?
Embedded fin tubes are pre-processed with embedded grooves on steel tubes, and then the fins are embedded in these grooves and fixed by welding or other means. The advantages are efficient heat exchange, compact structure, strong corrosion resistance and low pressure loss. The disadvantages are relatively complex manufacturing process and high production cost.
Wound fin tubes are made by winding fins on steel tubes. The advantages are simple manufacturing process, short production cycle and low cost. The disadvantages are short service life and low heat transfer efficiency.

Embedded G Type Fin Tube Application
The basic heat transfer element of the embedded fin tube for heat exchanger is the embedded finned tube. By adding fins outside the tube, the heat transfer area is greatly increased.
The main advantages of G type finned tube air cooled heat exchanger include high efficiency, corrosion resistance, low noise, energy saving and environmental protection.
Embedded fin tube economizer can effectively recover waste heat in flue gas, reduce exhaust gas temperature, improve boiler efficiency, reduce energy waste and reduce operating costs.
