Product Description

ASTM /GB Standard Welded Spiral Fin Tube Serrated Fin Pipe Boiler Economizer Steel Tubes

Description of Spiral Fin Tube pipe:
The round spiral fin /serrated fin pipes are mostly wound, high frequency welded and brazed spiral fin steel pipes.

Materials optional:
Tubes: Stainless steel, carbon steel, ND steel...Various material available,
Fin : Carbon steel, Stainless steel.....

The advantages of spiral fin steel pipes are as follows:
1. Long service life, is more than 20 years;
2. The surface of the fin is smooth, and it is not easy to produce ash accumulation, ash blocking and slagging.
3. It has good density, yield strength, tensile strength and wear resistance of metal structure.
4. The welding quality is high, so that it is not easy to cause unstable heat transfer performance because of fin loosening and falling off.





Application of Spiral Fin Tubes:
Waste heat boiler tube;
Economizer tube;
Power station boiler tube;
Marine boiler tube;
Heat exchanger
