High Frequency Welded Stainless Steel Spiral Fin Tubes Carbon Steel Spiral Finned Tubes

Description of Spiral Finned Tubes:
The spiral fin steel pipes currently used are mostly wound, high frequency welded and brazed spiral fin steel pipes.

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

Finned Tube as a part of air heat exchanger,it takes a very important roles here.
