| 用剪刀按使用长度垂直简短PP-R管，要保持断口平整不倾斜 |
| According to the length to straight cut off the PP-R pipe with a scissors so guarantee the opening neat and not len. |
|
| 首先将管材及管件熔接表面的灰尘、脏物除净，当熔接机加温至260℃，指示绿灯变红灯时（260℃自动变红灯）将管材及管件垂直插入热熔接焊头。 |
| at first clesning the dirty things off the pipe and pipe melting material, at melting temperature up to 260℃,and the green indicator changing to red, (at 260℃， the indicator becomes red naturally), putting the two directly into the hest-melting head. |
|
| 充分加热后，将管材与管件拨出，迅速垂直插入并维持一段时间，正常熔接在结合棉应有一均匀的熔接圈。 |
| Heating fully,pulling out the pipe and pipe material and virtually insulting into and maintaining for some time. under a normal melting, the joint surface should have an even melting joint circle |

操作图例：
1、在竖井中安装管道
如果在主管的两个支管的附近各装一个锚接物，这样主支管就 可以 在两个楼板之间竖直产生膨胀或收缩，竖井中两个锚接点 间的距离 不能超过30厘米，也可以用其它方法来补偿膨胀现象。例如从主管的分 管中装设“膨胀支管”。
1、If an anchorage connector installed adjacent to two branches each The main pipes will expand & cold conditions verticalty between the two floors. The distance between the supports shall not exceed 30m, other means can also be used to compensate, e.g.,install a expand brand pipe in the branch of the main pipe. |

2、暗敷管道
镶嵌到墙壁、楼板、样板等处的管道是能够防止膨胀的。压力和拉伸应力都被吸收而又不损坏各种材料。如果管道有隔离材料（要符合标准），则能允许更多的膨胀，
2、Hidden pipe layout
The pipes embedded into walls and floors can ptevent espansion, the decoration must be done with the materials to adsorb pressure and elongation force without being damaged. in case there is partitiong materials (meet with standard) in the pipe, the materials shall tolerate more expansion. |

3、外装管网
3.1用机械约束的方法防止膨胀ф20-25
支撑管网也常常采用钢槽吊钩固定在槽上，而槽又能起到固定管道的作用（使用电缆夹）这种施工方法能把塑料管的膨胀量降低到和钢管一样。
3、Pipe network installed outside
3.1Use mechanic binding method to prevent expansion. ф20-25
Steel groove hook is ususlly fixuped to the grove to support pipt network. Also this groove has the effect of fixuping the pipeline. This method can play down the volume of expansion of plastic pipe to be the same to the steel pipe |

3.2、用膨胀回路补充膨胀ф32-110
管网方向改变的各处均可以用来补偿线膨胀量。但是，在8米之内要用一种膨胀回路（U回路），这种方法主要用于ф32以上的管道。在安装锚接物时，要注意把管道分成各个部分，而膨胀力又能被导向所需的方向。
3.2、Use U loop to compensate espansion, ф32-110
The place where pipe network direction changes can be used to compensate linear expansion. In special case, U loop can be used to compensate at 8m inside, mainly for above ф32MM pipes. Attention must paid to split the pipe into several sections when anchoring piece is instanlled and espansion force can be oriented to the direction needed. |
