Produkt-Beschreibung

ASTM A179 Carbon Steel Embedded G Fin Tubes For Air Cooled Condensers ACC

 

ASTM A179 seamless carbon steel G-type finned tubes utilize ASTM A179 cold-drawn seamless low-carbon steel tubes as the base pipe. Through a mechanical embedding process, metal fins are inserted into a spiral G-shaped groove on the outer wall of the tube and secured in place. The enhanced heat transfer efficiency of G-type finned tubes facilitates compact equipment design. The mechanical embedding process increases surface friction, preventing the fins from detaching under conditions of vibration or thermal cycling.

 

Core Advantages

 

A179 seamless pipe: Low cost, good weldability, and stable mechanical properties under pressure and thermal cycling conditions.


Embedded G-type fin structure: High-temperature and vibration resistance, long service life, and low maintenance costs.


Compact layout: Large air-side heat transfer area.

The finning is tight — you can tell they used a proper cold-forming process because the fins don't move at all when you try to wiggle them. We've had issues before with other suppliers where the fins would come loose after a few thermal cycles, but these ones feel solid.
