r 9. 使用方法:
r (1)安装:管与管、管与件之间,可采用加热承插法。用油加热或喷灯加热到一定温度时,迅速将另一根管插入热管中,使之接入长度为管径的1.5~3倍时即可,然后慢慢放入管沟中进行填埋,其埋设深度应在当地平均冻土层以下。
r (2)使用:在使用时一定要加设保护装置。用压力罐供水或水泵调频直接供水时,除在管道顶端安装止回阀外,还应安装进气阀,以防在停泵时出现水倒流形成负压,造成管道损坏。另外,如遇地形高低不平时,在管道铺设时,应当每个管道的高点设一进气阀,目的也是避免管道产生负压。
r 10. 运输和储存:
r (1)装卸和运输时,不得暴晒、玷污、重压、抛摔和损伤;
r (2)储存时,管材堆放应整齐,应远离热源、油污和化学污染地,地面平整,库房应通风良好,室外堆放应有遮盖物。
r 11.注意事项:
r (1)管材在运输、装卸、安装过程中,严禁抛扔和激烈撞击,不能在地面上拖拉,以免对管材进行损坏。
r (2)管材在安装前,应对沟底进行清理,把可能对管材造成损坏的砖块、岩石等坚硬的物体进行清理。
r (3)管道安装铺设完毕后,应尽快回填,回填时,土中不应含有冻土块、砖块、大于20mm的石块及其他有碍管道使用的物体。
r 12、使用年限:在正常的适用水压范围内一般可使用50年。 r r
