Selection of floor heating pipes: First of all, floor heating pipes usually use PERT pipes, preferably PE-RT pipes with an oxygen barrier layer. Floor heating pipes usually include PE-Xa, PE-Xb, etc., and aluminum-plastic composite pipes are also used. The hardness of the aluminum-plastic composite pipe series is relatively high, so attention should be paid to the construction operation. PE-RT pipe has good flexibility and excellent heat resistance, and the pipe with oxygen barrier layer can prevent oxygen from penetrating into the pipe. PE-RT pipes can be repaired by hot melting, and are relatively firmer after repairs; however, aluminum-plastic composite pipes have better pressure resistance, heat resistance, and longer service life, but the cost is relatively high, and they are generally less used as floor heating pipes. Mostly used for pipeline laying.
