ASTM A106 GR.B Carbon Steel U Bend High Frequency Welded Fin Tube
What is high-frequency welded finned tube?
As the main heat dissipation component， high-frequency welded spiral finned tubes have excellent heat dissipation， which is several times or even dozens of times that of ordinary light tube radiators. They have excellent heat dissipation effects and are widely used in various fields and large areas. The service life of spiral wound tube radiators is generally 30 years. If the user maintains it correctly and excellently during use， its service life can be extended to as long as 50 years.
Advantages and applications:
High frequency welded finned tubes can meet the indoor heat demand. High frequency welded finned tubes have a wide range of applications， strong adaptability， and can be used for heat dissipation and heating in various fields. High frequency welded finned tubes have high flexibility and adaptability. It can be used for heating in various fields and places， and has been widely used in industries， agriculture， and other fields. In the industrial field， it is usually used in large workshop buildings， and the types and sizes of radiators applicable to different workshop buildings vary.
