浅析聚丙烯管道施工中应注意的问题

Problems should be Paid Attention to in the Construction of Sallow Polypropylene Pipeline

针对建设各方主体对聚丙烯管材线膨胀系数大的特性了解和重视不足,分析了聚丙烯管道在应用中几个较为突出的问题,提出采用暗敷安装、利用自然补偿、固定支架设置及利用适用于塑料给水管道的补偿器等措施,减少或克服因管材热膨胀引起的轴向伸缩。

In construction of all the big 4 coefficient of polypropylene pipes and characteristics, analyzed the polypropylene in- sufficient attention in the application of pipeline several prominent question, proposed by using natural compensation is installed, and fixed bracket and utilization is suitable for the plastic water-supply pipe compensator, reduce or overcome by thermal pipes of axial expansion.
