    Material and type of finned tube

    Weldable fin material: carbon steel, corrosion resistant steel, stainless steel, alloy steel

    Weldable fin form: high frequency welding


    High frequency welding spiral finned tube is a new type, wear-resistant and efficient heat exchange material, which is an efficient and energy-saving heat exchange element. It uses the national patent technology to use the high frequency welding production process, and uses the high frequency power supply as the heat source to heat the steel strip and steel tube at the same time, so that they can be fused and welded together. It has high heat exchange efficiency, large heat dissipation area, long service life and temperature range Wide range, high pressure. It is widely used in waste heat recovery, petrochemical industry, power station boiler, economizer, bus, heating, refrigeration, medicine drying, wood drying, grain drying system and other industries.


    2. Advantages of high frequency welding spiral finned tube


    a. The installation is simple and economical. The maximum length of the high-frequency welded spiral fin tube can reach 6 meters, reducing the connection point, making the installation more economical and fast, and reducing the probability of water leakage at the connection point.

    b. The maintenance is simple. After the installation of high-frequency welded spiral fin tube, the maintenance is basically unnecessary.

    c. High efficiency. The high-frequency welding spiral fin tube is the full contact welding of the fins and steel tubes. The heat dissipation area is more than 8 times of that of the plain tube. The inner part is more smooth and the internal flow resistance is small.

    d. It has a long service life, high mechanical strength of the combination of fins and pipes, and tensile strength of over 200MPa. All inside and outside of the pipes are hot-dip galvanized.

    Weldable fin material: carbon steel, corrosion-resistant steel, stainless steel, alloy steel

    Weldable fin form: solid tooth, open tooth


    3. Application of high frequency welding spiral fin tube


    High frequency welded spiral fin tube is a kind of high efficient heat transfer element. Its heat transfer area is several to dozens of times that of smooth tube, which can enhance heat transfer, reduce flow resistance, reduce metal consumption, and improve the economy and operation reliability of heat exchange equipment. At present, the high-frequency welding spiral fin tube has been widely used in chemical industry, electric power, metallurgy, petrochemical, boiler, building materials, textile, environmental protection, drying, medicine and other fields.
