The problem of pipeline antifreeze in winter can be solved by electric heat tracing
由于冬季温度相对较低，在磷酸管道输送过程中，由于热量损失，介质温度会降低。如果管道输送时间更长，热损失将更快。该温度适用于磷酸介质的逐渐凝固，这会导致管道堵塞，无法正常输送。因此，有必要使用电加热带等隔热方法来隔离和冻结磷酸工艺管道，并保持磷酸处于流动的液体状态，解决冬季管道防冻的问题。
加热带通电后，对管道的热损失进行补偿，以保证管道的正常输出。由于磷酸是工业产品，且位于化工场所，因此需要选择防爆、防腐、阻燃的电保温产品。此外，磷酸工艺管道较长，磷酸维持的温度也较高，因此可以选择串联恒功率加热带。串联型恒功率电加热带适用于电路长度超过并联恒功率电发热带的上限的情况。具有单个电源点的电路可长达千米，特别适用于长距离管道的隔热和伴热。
串联式恒功率加热器是一种以芯线为加热体的电加热产品，即通过电流芯线在具有一定阳极的芯线上传递而产生焦耳热。由于芯线的单位长度电阻和通过芯线的电流在整个长度上是相等的，并且加热能力在任何地方都是相等的。因此，它主要适用于长距离管道的绝缘和伴热，并使用一个电源点供电。可用于一般和防爆场合，I级和II级，2区。
