Waterproof casing has been widely used in building water supply and drainage engineering; it can effectively realize the mutual isolation wall and pipeline, to avoid adverse impact on both interactions so as to prevent the happening of the leakage phenomenon. Waterproof casing is a product emerging in construction engineering, is also an integral part of the pipe through the wall products. According to the needs of the demand of the medium and the field environment, on the structure of waterproof casing gradually formed a rigid waterproof and flexible waterproof casing pipe two kinds big. In waterproof demand higher water tank interior wall through, due to demand better sealing, using the flexible waterproof casing can be competent. Through the building floor and toilet wall to install rigid waterproofing casing only play a role under the wall and floor of vertical pressure. Generally the high cost of flexible waterproof casing, without strict requirements. Both are implemented according to the atlas, in the use of such as have not understand place to turn 02 s404 water-proof casing atlas, Locke surplus here a brief introduction to the users a confusing problem, the outside diameter of the wear waterproof casing pipe diameter is not consistent, otherwise can't use, general waterproof casing diameter than the steel pipe in a model. So the user friends when inspection products should pay attention to the small details. Although waterproof casing is a simple valve pipe fittings, but the firm soft coexist reflect the characteristics of the power of the modernization construction workers, even if is itself also can become avenue, in the future, in the modernization construction of waterproof casing value will be more and more obvious.
