Technical Requirements Analysis of Fire Electric Heat Tracing in Installation Process
Technical Requirements Analysis of Fire Electric Heat Tracing in Installation Process Piping systems are very common in buildings, such as domestic hot water pipes, fire pipes, etc. In winter, due to temperature effects, pipes are prone to freezing and blockage, so the pipe anti-freezing system plays a very important role in buildings. While installing insulation systems for pipes, environmental protection must also be considered, so the use of electric heat tracing systems is becoming more widespread.
Fire pipes use electric heat tracing systems for insulation. The installation process of electric heat tracing determines the quality of later insulation. Fire pipes are often buried underground and in dark tunnels. Due to concerns about low external temperatures, the voltage value that the electric heat tracing bears is relatively large. In addition, most electric heat tracing equipment manufacturers now choose the self-limiting temperature mode. When the gap between the temperature and the self-limiting temperature is too large, the change in resistance is very
