ASTM A106 Gr.B Embedded Finned Tubes with CU-T2 Copper Fins for Air Coolers
Product Overview

ASTM A106 Gr.B Embedded Finned Tubes with CU-T2 copper fins are engineered for high-efficiency air-cooled heat exchangers and industrial cooling systems requiring superior thermal conductivity and long-term operational reliability. The embedded fin manufacturing process mechanically inserts and locks the copper fin strip into a precisely machined groove on the carbon steel tube surface, creating a strong metallurgical-like bond that ensures excellent heat transfer performance and resistance to fin loosening under thermal cycling.

Combining the mechanical strength of ASTM A106 Grade B seamless steel tubes with the exceptional thermal conductivity of CU-T2 copper fins, these finned tubes are widely used in air coolers, process coolers, gas coolers, oil coolers, compressor aftercoolers, power generation facilities, petrochemical plants, and HVAC heat recovery systems.

Key Features
  • High heat transfer efficiency due to high-conductivity CU-T2 copper fins.
  • Excellent mechanical strength provided by ASTM A106 Gr.B seamless steel tube.
  • Strong fin-to-tube bond achieved through embedded fin technology.
  • Superior resistance to vibration and thermal fatigue.
  • Reduced air-side thermal resistance.
  • Extended service life in industrial cooling applications.
  • Suitable for high-pressure process systems.
  • Optimized design for compact heat exchanger construction.
  • Lower operating costs through improved energy efficiency.
Manufacturing Process

Embedded finned tubes are produced by machining a continuous helical groove into the external surface of the ASTM A106 Gr.B tube. A CU-T2 copper fin strip is then mechanically wound and tightly embedded into the groove. The base tube material is displaced around the fin root to securely lock the fin in place.

This manufacturing method provides:

  • High fin attachment strength.
  • Excellent thermal contact between fin and tube.
  • Uniform fin geometry.
  • Reliable operation under continuous thermal cycling.
  • Reduced risk of fin separation compared with conventional wound fin tubes.
