——对于穿楼板的套管，不必多言；
——对于过建筑物内墙的套管，怎样利于维修，重庆防水套管没有经验的，恐怕不好想象。
管道安装时，操作者的空间利用范围很大，可以自由运用。用户入住以后的维修、和管道的更换（达到使用年限等），操作者的空间很有限。
只能利用管道支架、和套管临时固定管道，进行相应的操作。
同时，套管的设置，还可以避免更换管道时，对居室内装修的***――如果不设套管，在进行上述操作时，就会在管道过墙部位，产生墙面损坏。
“有水房间的套管，还有一定的防止水渗、流、淌到下层的作用”
——“防止”有两个方面，一方面，指工程竣工以后，用户在装修阶段，不当的原因，造成自来水流淌，经套管流下层；另一方面，用户进驻后，意外原因，造成自来水流淌，经套管流下层。而且，前者往往多于后者。
流淌下层的原因有二，一是套管的高度低；二是，高度虽够，但套管口密封得不严。
"Protect the pipe from damage.""
- plastic pipes cross the floor and need protection.
For example, the above all about U-PVC drainage plastic pipe plus casing approach, that is, to prevent the root of the pipeline by external damage to a protective measure. Plastic pipes are most afraid of damage from the roots because they are difficult to maintain.
Similarly, for plastic water supply pipes, the installation of the casing on the floor, not only to c***ider the c***truction or maintenance, but also to protect the roots from being destroyed. As we all know, plastic water supply pipe sleeve is not necessarily through the floor, but the height of the floor has a definite requirement, the purpose lies in this. (visible, detailed and detailed).
- based pipeline wall, common concrete shear wall, but also the installation of casing, protect the pipeline when building settlement, through the gap between the casing and the pipeline, pipe repair to you with the difference settlement of buildings, reduce the pressure on the pipeline building.
When the pipe is through three seams (expansion joint, settlement joint and shock proof joint), the pipe is not to be broken or twisted due to uneven settlement on both sides of the three seam of the building. This kind of casing often has special requirements. Can be customized according to design requirements.
The geothermal coil is provided with a bushing to protect the heat pipe by opening the expansion joint in the middle of the room.
"Installation of pipes and servicing of pipes" is a deviation of the size or the allowable deviation of the size beyond the standard. The "size" here refers to the outer diameter and the wall thickness of the steel pipe. Usually, people call the size exceeding the tolerance ', which means that deviati*** and tolerances are not exact and should be called' deviati***'. The deviation here may be 'positive' or 'negative', and there is very little 'positive and negative' deviati*** in the same batch of steel tubes.
