Pipeline heaters are a kind of equipment used in operation and life. For example, electric furnaces, electric irons, electric irons, electric heaters, electric ovens, etc. are all attributed to electric heating equipment.
The resistance wire of the pipeline heater is made of nickel or chrome alloy and has a temperature of up to 800 °C. Because the power of the electric heater is relatively large, if the user neglects safety, the fire may occur at any time. The electric heater has the following factors: First, placing the electric heater on the flammable material or placing it in the vicinity of the flammable material, causing a fire under long-term high-temperature baking. two
The electric heater is not equipped with a device plug, and the electric wire head is directly pierced into the socket, so that a short circuit may occur and a fire may occur. Third, the operator does not remove the plug of the electric heater when it is detached. The electric heater is overheated and the adjacent combustibles are ignited to form a fire. Fourth, the resistance wire is repeatedly repaired and then used continuously, which can cause a line overload and cause a fire.
Therefore, when using, it is not allowed to place flammable and explosive materials in the vicinity of the electric heater, and it is necessary to maintain a certain safe distance. It is necessary for the electric heater to be placed on the base of the non-combustible material that is not thermally conductive; the safe interception of the electric heater wire is necessary to satisfy the capacity request of the electric heater, and the industrial electric heater must be equipped with a separate circuit under any circumstances.
