重慶鋼制防水套管套管耐污及潮濕，無需特別維護，只需定期地清楚表面污物。安裝時，母排從中穿過。B,C型適用于球墨鑄鐵鋼管及鑄鐵管。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, age 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與連接器外殼緊密接觸，防水套管分為剛性防水套管和柔性防水套管。兩者主要是使用的地方不一樣，柔性防水套管主要用在人防墻，水池等要求很高的地方，剛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，管道穿混凝土樓板、普通磚墻時，一般都在混凝土樓板上預留孔洞，普通磚墻可以后鑿過墻眼。樓板處，在安管道之前，掉通線、安裝套管。磚墻上，柔性防水套管和剛性防水套管都是用于管道穿過受有振動或有嚴密防水要求的建筑物墻壁的五金配件，常用于建筑、化工、鋼鐵、自來水、污水處理等單位。為保證管道不被建筑物三縫兩側(cè)的不均于沉降而折斷、重慶防水套管或扭曲等，通常，也要設套管。這種套管往往有特殊的要求?？砂丛O計要求訂制。畫線，栽設支架，找好坡度，安裝套管。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 件的彈性材料所形成。套管的重量以L=300計算，如墻厚大于300時，應另行計算。柔性防水套管一般適用于管道穿過墻壁之處受有振動或有嚴密防水要求的構(gòu)筑物；室外給水管道，因條件限制，距化糞池凈距小于規(guī)范要求，剛性防水套管適用于管道穿墻處不承受管道振動和伸縮變形的構(gòu)（建）筑物，適用于管道穿墻處空間有限或管道安裝先于構(gòu)（建）筑物或管道的更新改造。成都柔性防水套管對于有地震設防要求的地區(qū)
