密闭套管的直径可分为外径、内径、公称直径，管材为无缝钢管的管子的外径用字母D来表示，其后附加外直径的尺寸和壁厚，例如外径为108的无缝钢管，壁厚为5MM，用D108*5表示，塑料管也用外径表示，如De63,其他如钢筋混凝土管、铸铁管、镀锌钢管等采用DN表示，在设计图纸中一般采用公称直径来表示，公称直径是为了设计制造和维修的方便人为地规定的一种标准，也较公称通径，是密闭套管（或者管件）的规格名称。具体做法是在结构墙体上和窗框之间做一道防水，套管防水堵漏外墙和窗户整个的周边做一道防水。或者做两个框，一个主框，一个副框。二手房装修时改窗户的情况比较多，很多业主因为想扩大空间，就将窗户向外移，本来窗框是结构墙体平着的，把窗往外移，就变成上窗框和保温层平齐。

密闭套管管材在运输，装卸及堆放过程中严禁抛扔或激烈碰撞。管道的铺设应在验槽合格后方可进行，在铺设管道前要对管材，管件等重新进行一次外观检查，发现有问题的管材和管件均不得使用。防腐油漆的重要性在于我们厂家在制作好密闭套管后，为了方便客户现场使用时不会安装错误，所以都会整体喷腐蚀油漆， 内壁和外壁均匀的喷一遍，然后才在套管上喷上型号。B型刚性密闭套管说明：\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\u3000\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\u30001.套管穿墙处如遇非混凝土墙壁时，应改用混凝土墙壁，其浇注范围应比翼环直径（D4）大200，而且必须将套管一次浇固于墙内，套管内的填料应紧密捣实。\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\u3000\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\u30002.当用于饮用水水池安装时，应在水泥与水接触侧嵌填无毒密封膏。\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\u3000\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\u30003.密闭套管的焊接结构尺寸公差与形位公差按照JBT5000.3-1998执行。焊接采用手工电弧焊，焊条型号E4303，牌号J422。焊缝坡口的基本形式与尺寸按照GB985-88执行。刚性密闭套管是钢管外加翼环（钢板做的环形套在钢管上），装于墙内（多为混凝土墙），用于一般管道穿墙，利于墙体的 防水，而柔性密闭套管除了外部翼环，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。

柔性密闭套管近年来发展可谓非常迅速，直接带动整个国内的重工业行业的经济指数。产品的优势也是显而易见的，这主要还是要归功于国内整的大力支持，以及国内的建筑行业的告诉发展，才能让他产品的性能完整的展现在世人面前。密闭套管主管采用球墨铸铁管，橡胶圈承插接口，过桥管采用D325×8焊接钢管，沿路预埋支管采用D219×6焊接钢管。施工前需对管件及阀门进行试验检测，其压力等级不应低于管道工作压力的1.5倍，材料进场后及下管前要对管材及附件进行检验，包括文字证明和实物检查。密闭套管管材在运输，装卸及堆放过程中严禁抛扔或激烈碰撞。管道的铺设应在验槽合格后方可进行，在铺设管道前要对管材，管件等重新进行一次外观检查，发现有问题的管材和管件均不得使用。密闭套管管材的吊运及放入槽内时，应采用可靠的软带吊具，平稳下沟，不得与槽底和槽壁发生剧烈碰撞。配管时沿沟槽分散配置，减少二次搬运，为确保下管位置的准确，需在管内放置带有中心刻度的水平尺，检验时看管道坐标中心线上下垂的中心吊线与水平尺的中心是否重合。
