Product Name: Electric Fin Tube | Finned Tubular Heaters
- Leave Your Message
Electric fin tubes, also known as finned tubular heaters, are heating devices with a stainless steel tube outer shell, a built-in high-resistance electric heating alloy wire filled with modified magnesium oxide powder, and metal fins wrapped around the outer surface. They are used in machinery manufacturing, automotive, textile, and other industries.
Electric Fin Tube Process
An electric fin tube is a device with fins wrapped around the outer surface of the heating tube to dissipate heat.
Finned Electric Heater Function
Finned electric heater tubes utilize stainless steel heat sinks to increase the heat dissipation area by 2-3 times, and can achieve a surface power load 3-4 times that of conventional components. Manufactured using advanced production equipment and processes, and subject to strict quality control, they are widely used in machinery manufacturing, automotive, textile, food, air conditioning air curtains, and other industries.

Finned tubular heaters Types
Finned tubular heaters include straight, U-shaped, multiple U-shaped, and special-shaped bends. Materials include stainless steels such as SUS304, SUS321, and SUS316L. Operating temperatures range from low to medium temperatures (≤350°C) to high temperatures (>700°C). Voltages support 12-660V, with single-shot power ranging from 50W to 9kW. Flange or threaded mounting is available to accommodate various pipe sizes.
Electric Fin Tube Features
Fin electric heating tubes offer fast heating, high thermal efficiency, and a compact size. They are suitable for heating air, heating chemical materials, heating crude oil, and in explosion-proof environments.
Finned tubular heaters Applications
1. In the chemical industry, heating chemical materials, drying certain powders under pressure, chemical processes, and spray drying all require fin electric heating tubes.
2. Heating hydrocarbons, including crude oil, heavy oil, fuel oil, thermal oil, lubricating oil, and paraffin wax.
3. Heating fluids requiring heating, such as process water, superheated steam, molten salt, nitrogen (air), and water gas.
4. Due to the advanced explosion-proof structure of the finned heating tube, the equipment can be widely used in explosion-proof locations such as the chemical industry, military industry, petroleum, natural gas, offshore platforms, ships, and mining areas.
