Product Description

High Quality Boiler /Heat Exchanger Steel Tubes Mass Production With ASTM CCS BV DNV/GL LR Approved

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

The advantages of steel fin tube 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.
