Steel wall pipe embedded pipe

Flexible waterproof casing is applied to the pipe through the wall at the close by vibration or water structures required hardware fittings, the general production enterprises are developed based on the design of Building Research S312,02S404 standard atlas manufacturing. Flexible waterproof casing wall at the wall, when in case of non-concrete walls instead of concrete, it must be solidified in a casing wall; flexible waterproof casing facilities are widely used in construction, chemical, steel, water, sewage treatment and other units. Rigid waterproof casing is a steel pipe plus wing ring (steel ring set to do on the pipe), installed in the wall (mostly concrete walls), for general pipeline wall, the wall of water in favor, while flexible waterproof casing in addition to external wing ring, internal as well as stalls circle and the like, Falanneisi, complete sets to sell, but also their processing, there is damping the need for piping, pumps and pipes such as when connected through the wall. Either rigid or flexible waterproof casing is waterproof casing for pipeline through by vibration or water tight walls of buildings required hardware accessories, commonly used in construction, chemical, steel, water, sewage treatment and other units. Rigid waterproof casing and flexible waterproof casing most intuitive different appearance is different, flexible waterproof casing internal rubber seal ring, such as when used in the pool wall to prevent leakage. They are not the same installation length, standard length of the flexible sleeve is 300mm and standard rigid sleeve length is 200mm, but they have in common is that you can lengthen or shorten any necessary construction.
