Waterproof casing manufacturers can realize the transformation of economic development mode

      Waterproof casing is also called through the wall casing, through the wall pipe. Flexible waterproof casing is generally applicable to pipeline through the wall where subject to vibration or have strict waterproof requirements of the building, casing part of the processing is completed, in its outer wall are brushed with primer once (primer including camphor or cold primer oil). Waterproof casing is divided into rigid waterproof casing and flexible waterproof casing. The two are mainly used in different places, flexible waterproofing casing is mainly used in the human defense wall, pool and other demanding places, rigid waterproofing casing is generally used in the basement and other pipelines need to penetrate the pipeline location. 

    Rigid waterproofing casing is a steel pipe outside the wing ring (steel plate made of ring-shaped sets in the steel pipe), installed in the wall (mostly concrete walls), for general pipeline through the wall, conducive to the waterproofing of the wall, and flexible waterproofing casing in addition to the external wing ring, there are internal gear ring and so on, flange wire, there are complete sets of sales, but also can be processed, used for vibration-damping needs of pipeline, such as and pumps connected to the pipeline through the wall.
