Due to the production process, the length of the alloy wire will affect the resistance of the alloy wire, which will affect the power of the heating pipe. The power error of the electric heating pipe exists, but the power of the electric heating element is according to the "JB/T 2379-93 Industrial Electric Heating Tube Standard". The deviation range of the rated power is as follows:
Under sufficient heating conditions, the deviation of the rated power of the electric heating pipe should not exceed the range specified below:
1, for electric heating element rated power less than or equal to 100W electric heating pipe: ±10%;
2. For electric heating pipes with rated power greater than 100W: +5%~-10% or 10W, take the greater one.
