Pipe heater is an electric heating equipment heated by its medium in the pipeline. It can be heated by liquid or gas. It consists of a temperature control unit composed of a single chip computer and a temperature sensor. It also has two bush-like metal inner shells. An electric heating tube is fixed separately on the inner wall of the two metal inner shells. There are also two axle-bush shaped heat conduction layers made of heat conduction data for sleeving on pipelines, the outer wall of which is connected with the inner wall of two metal inner shells, and two axle-bush shaped heat preservation layers which are connected with the outer wall of two metal inner shells, with two axle-bush shaped shells on the surface of the two formed heat preservation layers. A fixing member is also provided for clamping the heating assembly on the pipeline. Pipe heater has the advantages of high thermal efficiency, convenient device and disassembly. It is widely used in various pipeline heating occasions. The resistance wire of pipe heater is made of nickel and chromium alloy, and the temperature is over 800 C. Because the power of the pipe heater is relatively large, if the user neglects safety, fire may occur at any time. The factors causing the fire of the pipe heater are as follows: One is to place the electrified electric heater on the combustible material or near it, which will cause fire under long-term high-temperature baking. ? Second, the electric heater has no device plug, which directly pierces the wire head into the socket, so it is easy to cause short circuit and fire. ? Thirdly, the user did not pull the plug of the electric heater out when he left, and it took too long to make the electric heater overheated, which ignited the nearby combustibles and constituted a fire. ? Fourth, the continuous use of resistance wires after repeated repairs can cause fire due to overload of lines. ? Pipeline heater is mainly used in the pre-heating of asphalt, heavy oil, clear oil and other substances. It belongs to an energy-saving equipment. Pipeline heater manufacturer's primary device is before the equipment, which can better complete the heating of substances, but can not be used in long-term water and cold zone. Because the required heating environment, material and shape are different, the temperature of the pipe heater will also be different. |
