JIS Standard Carbon Steel Boiler Spiral Fin Tube For Power Plant SA192
Product Description(Fin Tube)
High-frequency resistance welding spiral fin tube is in be weldment
import high power high frequency current, by using the current
welding joint contact area and adjacent area to produce the
resistance of the hot melt welding contact surface to melt or half
of the plastic state, and then give the appropriate pressure
welding contact surface, thus complete finned tube welding work.
Spiral type finned tube heat exchanger elements maintain a high capacity for heat transfer, possess superior self-cleaning properties and retain the ability to effect flue gas waste heat recovery in boiler renovations. Convective heat transfer coefficient is proportional to fin pitch, but inversely proportional to fin height and fin width. Integrated heat transfer capacity is related to fin efficiency, convective heat transfer coefficient and finned ratio. Pressure drop increases with the increase of fin height and fin width.

Principle
• Spiral fin tube is a kind of boiler parts, to have two steel circular symmetry to be welded on fluorescent tubes to form fins .
Detail
In order to improve the heat exchange efficiency and extend surface heat transfer, spiral type finned tubes have been widely used in boilers and waste heat recovery in recent years. Spiral type finned tubes are derived largely from rectangle finned tubes. Because of their unique groove structure on the fin surface, spiral type finned tubes have excellent anti-wear and anti-fouling performance.
Structure
Our products can be modified according to our customers' needs and the situation.we design and manufacture safe,reliable and efficient spiral fin tubes.HD BOILER has also completed stand-alone product quality assurance systems.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
1. Impact test and Strength calculation report with applied materials information.
2. 100%NDT(non-destructive inspection) report of steel plate, tube and electrode
3. X-ray, γ-ray and liquid penetrant test inspection report (welding seam): to ensure the quality of the entire boiler
4. Hydraulic test report: ensure the standard working pressure and safety
