02s404密闭套管图集中已经明确的标明，当管道所穿构筑物，是承重墙或者是具有震动的时候，必须选用柔性密闭套管，如果没有，并且防水要求不高的地方，才可使用刚性密闭套管。柔性密闭套管按照02S404图集加工：以柔性密闭套管为例02S404密闭套管图集第7页表中DN标示的是密闭套管的型号，D1是该密闭套管里面可以穿过的管子外径，这个是确定该用哪个型号密闭套管的依据。N200后面的D3是226，因此外径超过226的管子就不能使用DN200的柔性密闭套管，穿不进去了。D4是法兰压盖上面螺栓孔的中心距，D5是法兰外径。比如图纸上标注这个水池上面要穿外径219mm的钢管，按照该图集D1下面219对应的是DN200，那就应该使用DN200的密闭套管。后面的D2标示的是柔性密闭套管的管我们使用的柔性密闭套管必须环境要选好，因为环境对柔性密闭套管也是非常有影响的，我们一般选择的环境都是在离裂缝较远的地方，尽量不安装在裂缝的周围，因为这样是很容易对柔性密闭套管造成损坏的。刚性防水翼环主要适用于一般的管道穿墙，有利于墙体的防水，该产品在制作时的做法主要有以下几点：

管翼环用于一般管道穿墙，利于墙体的防水；柔性密闭套管除了外部套管翼环，内部还有档圈之类的，法兰内丝 ，有成套卖的，也可自己加工，用于有减震需要的管路，如和水泵连接的管道穿墙时。也就是说，如果考虑墙体两面 的防水性能，就要选用柔性密闭套管；如果仅仅是考虑管道的穿墙，而不考虑穿墙后，墙体两面的防水性能以及管道 的位移变形，就可以选用刚性密闭套管。De、DN、d、ф的各自表示范围：
1、De--PPR、PE管、聚丙烯管 外径
2、DN--聚氯乙烯（PVC）管、铸铁管、钢塑复合管、镀锌钢管公称直径
3、d --混凝土管公称直径
4、ф--无缝钢管或有色金属管道应标注“外径×壁厚”，如：ф108 X 4
