<< review queue entry 79295 - submitted by 'richwarm' >> Electric heat tracing, heat tape or surface heating, is a system used to maintain or raise the temperature of pipes and vessels using heat tracing cables. Trace heating takes the form of an electrical heating element run in physical contact along the length of a pipe. The pipe is usually covered with thermal insulation to retain heat losses from the pipe. Heat generated by the element then maintains the temperature of the pipe. Trace heating may be used to protect pipes from freezing, to maintain a constant flow temperature in hot water systems, or to maintain process temperatures for piping that must transport substances that solidify at ambient temperatures. Electric trace heating cables are an alternative to steam trace heating where steam is unavailable or unwanted.[2] https://en.wikipedia.org/wiki/Trace_heating Web ~ "Steam tracing is a form of heat tracing that circulates steam around process pipes to keep the process media within a specific temperature range. Tracer lines are the tubing that carries the steam alongside the process pipe. Both electrical heat tracing and steam tracing are commonly used at process plants." 电伴热（Electric trace heating）是一种利用电能产生热量的加热技术。它通过在管道、容器、设备或其他需要加热的表面安装特殊的电阻材料（称为伴热带或伴热电缆），通过电流流过伴热带产生热量，以达到加热的目的。 |
