Product Description


The finned tube is a heat exchanger.Is to improve the heat exchange efficiency, usually in the heat exchange pipe surface by adding fins, increase the heat exchange pipe surface area (or internal surface area), so as to improve the heat exchange efficiency, such a heat exchange pipe.


Manufacture


High frequency and high frequency welding spiral finned pipe is one of the most widely used spiral finned pipe at HDB.It is widely used in power, metallurgy, cement industry waste heat recovery and petrochemical industry.High frequency welding spiral finned pipe is in the steel belt winding steel pipe at the same time, using the skin effect and proximity effect of high frequency current, the steel belt and the outer surface of the steel pipe are heated until the plastic state or melting, and the welding is completed under certain pressure of the wound steel belt.This high frequency welding is actually a solid phase welding.Compared with Mosaic, brazing (or overall hot dip galvanizing) and other methods, it is more advanced in product quality (fin bonding rate is high, up to 95%), productivity and automation.



Advantages


1.Anti - corrosion

2.Anti-wear

3.Lower contact resistance

4.High Stability

5.Ability to prevent ash accumulation


Features


1. The equipment body can be designed into many modules to ensure the long term and stable running;
2. Compact structure which can enlarge the heat exchanging area in order to add the heat transfer area and less leakage
3. Improve the heat transfer efficiency
4. Structure arrangement: In line or staggered arrangement


Details


1.Our products can be modified according to our customers' needs and the situation.

2.we design and manufacture safe,reliable and efficient H-fin tubes.HD BOILER has also completed stand-alone product quality assurance systems.
3.Production of H-fin tubes are with high heat transfer efficiency, they have flue gas resistance and are designed for a small space.

Quality Control


1Impact test and Strength calculation report with applied materials information.
2100%NDT(non-destructive inspection) report of steel plate, tube and electrode.
3X-ray, γ-ray and liquid penetrant test inspection report (welding seam): to ensure the quality of the entire boiler.
4Hydraulic test report: ensure the standard working pressure and safety.
