在生活热水系统中采用塑料管应关注其维卡软化温度

Application of Plastic Pipeline in Hot Water System

阐述生活热水系统中选用塑料管应该关注其“维卡软化温度”的理由,并提出一个由系统工作压力判断其极限高温和管材可靠性的方法。

The author of this paper indicated that, as a key factor in application of plastic pipeline for hot water system close attention must be paid to the Vicat softening point. Also a method using the working pressure of the hot water system to estimate the ultimate maximum temperature and the reliability of the pipeline material has been proposed.
