What is Enamel spiral finned tube?
Enamelled spiral finned tube refers to the enamel on the surface of high-frequency welding spiral finned tube, which has achieved the function of anti-corrosion.
1.Use high-frequency welding to weld spiral steel strip on the outside of seamless steel pipe to make finned tube.
2. Burn enamel on the surface of finned tube to make 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, light weight, low price, and strong corrosion resistance
Enamel spiral finned tubes have great advantages in reducing the exhaust gas temperature of boilers, improving the thermal efficiency and reducing the corrosion of the tail heating surface, and have great application prospects and economic benefits.
Enamel Spiral Finned Tube Usages
Enamel spiral finned tubes are widely used in power, petroleum, chemical, pharmaceutical, drying and other industries and fields. Such as: economizer, air preheater, air heater, gas heater, liquid heater, steam heater, cooler, radiator, flue gas heater, etc.

Performance characteristics of enamel spiral finned tubes
1. The corrosion resistance of enamel spiral finned tube is better than that of ND steel tube.
2. The wear resistance and ash resistance of enamel spiral finned tube are better than ND steel tube, and the service life is longer than ND steel tube.
3. Enamel spiral finned tube has 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 environment or high decorative performance.
