安装步骤

1、切割：切割管材，必须使端面垂直于管轴线。管材切割一般使用管子剪或管道切割机，必要时可使用锋利的钢锯，但切割后管材断面应去除毛边和毛刺。

2、清洁：使用洁净抹布清洁管材和管件的焊接部位（建议用酒精擦拭）、管材与管件连接端面必须清洁、干燥、无油污。

3、划线：按表1规定的熔接深度在管材上划线：

4、加热：热熔机加热后，将管材和管件无旋转地插入热熔模头，管材达到划线位置时停止：

5、焊接：达到加热时间后，管材管件无旋转地拔出，将管材无旋转插入管件承口内，按冷却时间停留。

注意：

同种材质的给水聚丙烯管与管配件之间，应采用热熔连接，安装应使用专用热熔工具。强调暗敷墙体，地坪面层内的管道必须采用热熔连接，不得采用丝扣或法兰连接。

给水聚丙烯管与金属管件连接，应采用带金属嵌件的聚丙烯管件作为过渡，该管件与塑料管采用热熔连接，与金属管件或卫生洁具五金配件采用丝扣连接。另外连接阀门、龙头与金属配件连接时，弯头、三通处要带有固定支座，牢固的固定在墙上。
