重庆钢制防水套管套管耐污及潮湿，无需特别维护，只需定期地清楚表面污物。安装时，母排从中穿过。B,C型适用于球墨铸铁钢管及铸铁管。Casing stain and wet, needs no special maintenance, only periodically clear the dirt. When installed, the bus through. B, the type of C is applicable to ductile iron pipe and cast iron pipe. Close contact with the connector shell, waterproof casing is divided into rigid waterproof and flexible waterproof casing. The two main uses are different, flexible waterproof casing is mainly used in the air defense wall, pool and other requirements of high places, rigid waterproof casing generally need to wear the pipeline position in pipe of underground chamber. Characterized by, pipeline through the concrete floor, common brick, reserved holes are generally in the concrete floor, common brick wall after wall eye can chisel. Floor, in the pipe before installation, off line, casing.成都防水套管 The brick wall, flexible waterproof casing and rigid waterproof casing is used for pipeline through a wall by vibration or strict waterproof requirements of buildings hardware accessories, commonly used in construction, chemical industry, iron and steel, water, sewage treatment and other units. In order to ensure the pipeline will not be three buildings on both sides of the joint to the settlement and uneven, broken or distorted, usually与连接器外壳紧密接触，防水套管分为刚性防水套管和柔性防水套管。两者主要是使用的地方不一样，柔性防水套管主要用在人防墙，水池等要求很高的地方，刚性防水套管一般用在地下室等管道需穿管道地位置。其特征在于，管道穿混凝土楼板、普通砖墙时，一般都在混凝土楼板上预留孔洞，普通砖墙可以后凿过墙眼。楼板处，在安管道之前，掉通线、安装套管。砖墙上，柔性防水套管和刚性防水套管都是用于管道穿过受有振动或有严密防水要求的建筑物墙壁的五金配件，常用于建筑、化工、钢铁、自来水、污水处理等单位。为保证管道不被建筑物三缝两侧的不均于沉降而折断、重庆防水套管或扭曲等，通常，也要设套管。这种套管往往有特殊的要求。可按设计要求订制。画线，栽设支架，找好坡度，安装套管。具有上述密封部的部件由硬度低于具有上述第二密封部的第二部 件的弹性材料所形成。套管的重量以L=300计算，如墙厚大于300时，应另行计算。柔性防水套管一般适用于管道穿过墙壁之处受有振动或有严密防水要求的构筑物；室外给水管道，因条件限制，距化粪池净距小于规范要求，刚性防水套管适用于管道穿墙处不承受管道振动和伸缩变形的构（建）筑物，适用于管道穿墙处空间有限或管道安装先于构（建）筑物或管道的更新改造。成都柔性防水套管对于有地震设防要求的地区
