What is Enamel spiral finned tube?
Enamelled spiral finned tube refers to the enamel on the surface of a high-frequency welding spiral finned tube, which has achieved the function of anti-corrosion.
1. Use high-frequency welding to weld spiral steel strips on the outside of seamless steel pipe to make the finned tube.
2. Burn enamel on the surface of the finned tube to make a finned enamel heat pipe Enamelled spiral finned tubes are suitable for waste heat recovery under low-temperature dew point.
3. Enamel Spiral Finned Tube|Enamel Tube are characterized by high heat exchange efficiency, small equipment size, lightweight, low price, and strong corrosion resistance
Enamel spiral finned tubes have great advantages in reducing the exhaust gas temperature of boilers, improving thermal efficiency, and reducing the corrosion of the tail heating surface, and have great application prospects and economic benefits.
Enamel Spiral Finned Tube Usage
Enamel spiral finned tubes are widely used in power, petroleum, chemical, pharmaceutical, drying, and other industries and fields. Such as economizers, air preheaters, air heaters, gas heaters, liquid heaters, steam heaters, coolers, radiators, flue gas heaters, etc.
Specification and model of enamel spiral finned tube
| O.D. (mm) | Enamel Thickness (mm) | Fin Thickness (mm) | Fin Height (mm) | Fin Pitch (mm) | Deposition Rate (%) | Length (mm) | Pull off Test (kg/mm²) |
| 20-165 | 0.20±0.05 | 0.5-4 | 10-40 | 4-40 | >95% | 13 | 27.5 |
Performance characteristics of enamel spiral finned tubes
1. The corrosion resistance of an enamel spiral finned tube is better than that of an ND steel tube.
2. The wear resistance and ash resistance of enamel spiral finned tubes are better than ND steel tubes, and the service life is longer than ND steel tubes.
3. Enamel spiral finned tube has a stronger convection heat transfer effect than ND steel tube and has higher heat transfer efficiency.
4. Enamel finned tube is mainly used for heat exchange in corrosive environments or high decorative performance.
