02S404 made of steel waterproof casing

Rigid waterproof bushing is the steel tube with external wing ring (annular made of steel plate on the steel tube), installed in the wall (mostly concrete wall), used for general pipe through the wall, conducive to the waterproof wall; In addition to the external wing ring, the flexible waterproof sleeve also has internal gear ring, flange inner wire, which can be sold in sets, or can be processed by ourselves, used for the pipe with shock absorption needs, such as the pipe connected with the water pump to go through the wall. In other words, if the waterproof performance of both sides of the wall is considered, flexible waterproof casing should be selected. Rigid waterproof casing can be used if the pipe penetration is considered only, and the waterproof performance of both sides of the wall and the displacement and deformation of the pipe are not considered.

Rigid waterproof casing is suitable for construction where the pipe passes through the wall and does not bear the vibration and telescopic deformation of the pipe. It is suitable for construction where the pipe passes through the wall and the space is limited or the installation of the pipe precedes the renovation of the construction or the pipe. For areas with seismic fortification requirements, such as the use of steel waterproof casing, the nearest flexible connection should be set on the pipe that enters the pool wall or the outer wall of the building. Type A for steel pipe, Type B, Type C for ductile iron pipe and cast iron pipe.
