Product Description
DELLOK SA179 G Type Bimetallic Finned Tube Heat Exchanger
Professional heat exchanger manufacturer with 20 years of experience, providing comprehensive heat transfer solutions for various industries including metallurgy, food processing, petrochemical, pharmaceutical, beverage production, wastewater treatment, and refrigeration systems.
Product Overview
The G Type Embedded Fin heat exchanger features a fin strip wound into a machined groove and securely locked into place by back filling with base tube material. This design ensures maximum heat transfer efficiency at high tube metal temperatures up to 450°C.
Manufacturing Process
A helical groove is formed in the base tube by displacing material. The fin is then wound into the groove under tension, followed by backfilling of the displaced material to lock the fin root securely into the tube.

Key Advantages
- Thermal Performance: Constant fin/tube wall contact enables operation at wall temperatures up to 400°C
- Mechanical Strength: Fin remains securely set throughout its length and does not unwind even when partially uprooted
- High Temperature Capability: Maximum operating temperature of 450°C
- Strong Bond: Pull-off force not less than 70N for reliable performance
Material Specifications
Fin Materials: Aluminum (ASTM B209 Al 1060, Al 1100, A1050) or Copper
Tube Materials: Carbon steel (ASTM A179, A192, SA210 GrA1/C), stainless steel (TP304, 316), copper alloys, titanium (B338Gr2)

Frequently Asked Questions
What is a fin tube?
Finned tubes are the main components of heat exchangers where fins are added externally to increase contact area with outside fluid, facilitating efficient heat exchange between internal and external fluids.
What is 'G' Fin Tube or Embedded Fin Tube?
Embedded fin tubes feature fins externally applied on base tubes. A continuous groove is formed on the base tube, the fin edge is inserted, and rollers backfill the groove to securely embed the fin in the base tube.
How is quality ensured?
Comprehensive quality control from raw material inspection through production checking, water pressure testing, and strength testing. Third-party inspection authorization available.
