How to connect a section of heating tape that is not long enough

If it is necessary to extend the length of the heating strip, the following steps can be taken for connection:
Determine the length that needs to be extended, and choose a suitable companion band according to the actual situation. 
When connecting the heat tracing strip, it is necessary to ensure that the two ends of the heat tracing strip are connected separately from the two ends of the electric heat tracing strip. The connection method can choose from welding or crimping.
Ensure close contact and reliable conductivity at the interface, while avoiding excessive temperature at the interface to prevent danger caused by waste heat.
During the connection process, attention should be paid to the matching of electrical parameters between the electric heating strip and the heating strip to prevent safety accidents.
There are two main methods for connecting electric heating belts: series connection and parallel connection: 
Series connection method. It is necessary to ensure that each heating strip is installed correctly and tightly overlapped, paying attention to polarity and avoiding connecting heating strips of different polarities together.
Parallel connection method. It is necessary to ensure that the polarity of each heating strip is correct, and consider the power capacity, not exceeding its carrying range.
