G Type Embedded Finned Tube

The G Fin Tube, also referred to as the Embedded Fin Tube, is designed for applications where higher operating temperatures and less corrosive environments are required.
In this design, the fins are created by embedding a fin strip into a groove on the base tube. After placing the fin strip in the groove, the space is filled to ensure a strong bond between the fins and the tube. This manufacturing method gives the G Fin Tube its name, as it is sometimes called the Grooved Fin Tube. This structure enhances heat transfer efficiency, making it suitable for various industrial applications.
Finned tubes have small fins on their outer surfaces that enhance heat transfer and filtration. The heat transfer typically occurs from the inside of the tube to the outside and vice versa. The efficiency of heat transfer in these tubes depends on several factors, including:
  • The temperature difference between the fluids vs gas
  • The heat exchange between the fluids and the tube walls
  • The surface area exposed to the fluids
  • There are various types of finned tubes produced by manufacturers, each suited for specific processes and equipment.
The G-Type finned tube, also known as the embedded-fin tube, gets its name from its grooved design. In this type, a fin strip made from materials like copper or aluminum is twisted into a machined groove on the base tube. This groove is then filled to secure the fin in place. The G-type fin tube is known for its strength and is commonly used in applications requiring high-temperature heat transfer.

logoFAQ

Fin Tubes, or Finned Tubes, are heat exchanger tubes designed to increase surface area for efficient heat exchange between air and fluid inside the tube.

'G' Fin Tubes, also called Embedded Fin Tubes, have fins inserted into a continuous groove on the base tube, then secured by backfilling the groove with rollers.

Extruded fin tubes are made from a base tube, typically carbon steel, stainless steel, or alloy steel, and a fin strip material, ensuring heat exchange efficiency.
