A型通风套管经常用在管道穿过铁道、马路、街道等处，为防止管道受荷载被压坏，而在管道外部设置保护性套管，如：大口径混凝土管道，大口径钢管等避免外力（荷载）直接作用在管道外壁上，造成管道破损，而采取的措施。我们都知道防水套管分为通风套管和通风套管，那么通风套管适用于管道穿墙处不承受管道震动和伸缩变形的构筑物，适用于管道穿墙处空间有限的地方或对管道的更新改造等。在进入池壁或者建筑物外墙的管道上的就近处要设置通风套管的连接。

防水套管连接卫生器具的排水管道接口应紧密不漏，其固定支架、管卡等支撑位置应正确、牢固，与管道的接触应平整。公共功能的管道，包括采暖供回水总立管、给水总立管、雨水立管、消防立管等，不宜布置在住宅套内。公共功能管道的阀门和需经常操作的部件，应设在公用部位。通风套管在制作时所采用钢材的说明：
1、角钢、工字钢和槽钢的准确计算公式很繁，表列简式用于计算近似值；
2、f值：一般型号及带a的为3.34，带b的为2.65，带c的为2.26；
3、e值：一般型号及带a的为3.26，带b的为2.44，带c的为2.24；
4、各长度单位均为毫米。
