Pipe electric heaters are composed of several tube-shaped electric heating elements, cylindrical bodies, and flow guides. The tube-shaped electric heating elements consist of a high-temperature resistance wire placed inside a metal tube, with a dense filling of crystalline magnesium oxide powder, which possesses good insulation and thermal conductivity properties, in the gaps. Using the tube-shaped electric heating elements as the heating element offers advanced structure, high thermal efficiency, good mechanical strength, and features such as corrosion and wear resistance.

The pipe electric heater is composed of several components, including tubular electric heating elements, a cylinder, and flow baffles. The tubular electric heating elements consist of high-temperature resistance wire placed inside a metal tube, with tightly packed crystalline magnesium oxide powder, which has excellent insulation and thermal conductivity properties, filling the gaps. Using tubular electric heating elements as the heating source offers advanced structure, high thermal efficiency, good mechanical strength, corrosion and wear resistance. The cylinder is equipped with flow baffles, ensuring even heating of the air during circulation.

Pipe electric heater, an electric heating device used for heating pipes or their internal medium. It consists of a microcontroller and a temperature sensor for the temperature control unit, and also features two metallic sleeve-shaped inner shells, with each inner shell having a fixed electric heating tube on its inner wall surface; it also includes two sleeve-shaped heat-conducting layers made of heat-conducting materials, designed to fit over the pipe, with their outer wall surfaces adhering to the inner wall surfaces of the two metallic inner shells; two sleeve-shaped insulating layers, adhered to the outer wall surfaces of the two metallic inner shells, with two sleeve-shaped outer shells on their outer surfaces; and fixed components for securing the aforementioned heating elements to the pipe. This invention boasts high thermal efficiency and ease of installation and removal, making it widely applicable to various pipe heating scenarios.

Application Range: Widely used in heating systems, industrial process water, power plant raw water, and air conditioning heating for steam heating.
