DN400人防密闭套管是有钢管加工制作的，在输送流体时阻力系数小，不混生细菌、 霉菌，具有良好的防蜡、防结垢机能。所以在一般情况下比同直径的钢管输送流体量多10%-20%，输送动力消耗低15% 以上，使用寿命高10倍以上。由此，在输送石油、自然气、煤气，以及输水或污水处理等管道系统中得到广泛的使用 。02S404人防密闭套管的尺寸因为使用安装建筑穿墙的型号口径不一样，人防密闭套管生产可以根据客户的使用安装要求图 纸加工定制加长型的人防密闭套管。柔性人防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。

CF3722套管制作安装、不锈钢人防密闭套管安装 公称通径小于等于150mm； 不锈钢人防密闭套管定额已经考虑了套管的做法，套用管道DN100的定额，实际上套管含的就是DN150的钢管。刚性人防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，（多为混泥土墙），用于一般管道穿墙，利于防水。柔性人防密闭套管除了外部翼环，内部还有挡圈之类，法兰内丝，用于减震需要的管路，如和水泵连接的管道穿墙时。主要是使用的地方不一样，柔性人防密闭套管主要用于人防墙，水池等要求很高的地方，刚性人防密闭套管一般用于地下室和管道需穿管到的位置，自地下入户的管道，穿建筑物外墙需加人防密闭套管。我国正面临着从农业时代向工业化时代的转变，将大幅增加工业对柔性人防密闭套管产品的需求。国家政策的支持和产品市场的巨大需求将是柔性人防密闭套管产业飞速发展的强大动力。随着柔性人防密闭套管行业重组步伐的加快，未来行业将是柔性人防密闭套管产品质量安全和产品品牌之间的竞争，我们生产柔性人防密闭套管产品必须向高技术、高参数、耐强腐蚀、高寿命方向发展，不断提高柔性人防密闭套管产品的水平和档次，这样才能在庞大的需求环境下呈现出更好的行业发展前景。\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\u3000\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\u3000套管可分为：普通套管－－比要用的管道粗2-4厘米，固定在墙或板内，管道从中通过。柔性套管－－就是在套管与管道之间用柔性材封堵起到密封效果。钢性套管－－就是套管与管道间用钢性材料封堵达到密封效果。人防密闭套管－－就是套管所使用的环境是防止液体漏出或漏入的地方（比如水池、化粪池、地下室等），就是在套管外壁增加不少于1圈的防水翼，这样套管浇筑在墙体内时就成为一个整体，不会因胀缩因数而出现裂纹而渗漏。

人防密闭套管说明：1. 柔性填料材料：沥清、麻丝、聚板、聚氯乙烯泡沫塑料板。 2. 密封膏：聚硫密封膏，聚胺脂密对膏 \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\u30003. 压力管道：设有安全阀的压力管道：管道设计压力≥安全阀开启压力；与未设安全阀的设备相连的压力管道：管道设计压力≥设备设计压力；离心泵出口管道：管道设计压力≥泵的关闭压力；往复泵出口管道：管道设计压力≥泵出口安全阀开启压力；压缩机排出管道：管道设计压力≥安全阀开启压力+压缩机出口至安全阀沿程最大正常流量下的压力降。 \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\u3000\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\u30004. 穿管处混凝土墙厚应小于300，否则应使墙壁一边加厚或两边加厚，加厚部分的直径至少为D5+200。套管的预留位置不准确：这一点与上面提到的人防密闭套管要在施工过程中安装相一致，如果不是按照这一原则进行安装，很可能大致预留出来的用于安装人防密闭套管的位置不够准确，进而导致整个施工无法正常进行。
