Product Description

ASTM A179 A192 Carbon Steel Seamless Finned Tube

Specifications
1.Highly competitive rates 
2.Lower contact resistance 
3.Anti - corrosion & water 
4.energy saving 
 
Fin tube is processed fin shape, and it has larger surface and higher heat conductivity than bare tube. Fin tube is easy to be bended and processed after annealing, and it is always used in generator of absober refrigerator,condenser and oil cooler of refrigeration system and used in heat transfer of other industries.
 
1.The finned tube is high stability when which is highly competitive rates
2.carbon steel,bright annealed
3.Good anti-corrosion and anti-wear.
4.Widely used for Boilers,firde heaters and heat exchanger

Manufacturing Process of ASTM A179 Finned Tube
Fin strips (usually aluminum and copper) are folded into an L shape and wound under tension on the surface of the base tube. The feet of the fins are connected together and cover the surface of the fins.
 
ASTM A179 Finned Tube is combined with two different materials
Core tube material: A179
Fin material: aluminum, copper, steel
1. Aluminum (Alu.1100, Alu.1060)
2. Copper.
3. Steel
