Stainless steel double H fin tube for boiler for power plant from China bare pipe stainless steel tube coil

Stainless steel double H fin tube Structure

1. Our products can be modified according to our customers' needs and the situation.we design and manufacture safe,reliable and efficient H-fin tubes.Dehai Boiler has also completed stand-alone product quality assurance systems.

2. Production of H-fin tubes are with high heat transfer efficiency, they have flue gas resistance and are designed for a small space.

Product Advantage

1. Add the heat exchange area and reduce the number of tubes, also increase the fume flow section area to reduce the fume speed and abrasion.
2. H type fin tube can be made to double H type fin tube, high rigidness to fit long tube row.
3. H type fin economizer arranged in line to make the space into many small zones, averaged air flow to reduce the abrasion.
4. With straight channel to gain the best ash-blowing effect.
5. The compact structure to reduce the weight and reduce the manufacturing cost.

Detail

In order to improve the heat exchange efficiency and extend surface heat transfer, H-type finned tubes have been widely used in boilers and waste heat recovery in recent years. H-type finned tubes are derived largely from rectangle finned tubes. Because of their unique groove structure on the fin surface, H-type finned tubes have excellent anti-wear and anti-fouling performance.

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.
