Flexible waterproof shell refers to the sealing effect of flexible material between shell and pipe. The rigid waterproof shell is sealed by the rigid material between the shell and the pipe to complete the sealing effect. What are the differences between the two in specific use?
The flexible waterproof shell is generally applicable to the structure with strict waterproof requirements when the pipeline is subject to vibration or passing through the wall; the rigid waterproof shell is generally applicable to the structure requiring general waterproof when the pipe passes through the wall.
The walls of flexible and rigid waterproof enclosures pass through the walls. If it is not concrete, concrete wall shall be used instead, and the casing pipe shall be dry fixed once on the wall; Waterproof casing For construction, chemical plants, steel, drinking water, wastewater treatment and other enterprises.
   Rigid waterproof casing It is a steel pipe with wing rings (the ring made of steel plate is placed on the steel pipe) and installed in the wall (mainly concrete wall). It is used to pass through the wall of the general pipe, easy to waterproof the wall; in addition to opening wing ring, inner hole, etc., the flexible waterproof shell is external, and the inner thread of flange plate is direct, which is sold in sets. It can also be processed independently for shock absorption pipe, such as pipe and water pump connecting through the wall. In other words, if the waterproof performance of both sides of the wall is considered, the flexible waterproof shell should be used; if only the pipeline passing through is considered, the rigid waterproof sleeve can be used regardless of the waterproof performance of the wall and the deviation of the pipe after the wall is damaged.
The rigid waterproof sleeve is applicable to the pipeline structure (structure) which does not bear the vibration and expansion deformation of the pipeline. It is suitable for upgrading pipes through walls or pipes before construction (construction) or pipelines. For areas with seismic fortification requirements, such as the use of steel waterproof casing, flexible connections should be placed around the pipe near the side wall or building wall. For the wall where the flexible and rigid waterproof casing passes through the wall, if it is not concrete, the concrete wall shall be used, and the casing shall be solidified in the wall at one time; the waterproof sleeve shall be used in construction, chemical industry, steel, tap water, sewage treatment and other units.
Rigid waterproof casing is steel pipe with flange ring (steel plate made of annular sleeve on steel pipe), installed in the wall (mostly concrete wall), used for general pipe through the wall, which is conducive to the waterproof of the wall; Flexible waterproof casing In addition to the outer wing ring, there are baffle rings inside, flange inner thread, which are sold in sets or processed by ourselves. They are used for pipes with damping requirements, such as when the pipe connected with the water pump goes through the wall. If the waterproof performance of the two sides of the wall is not considered, the displacement of the pipe can also be considered; if the waterproof performance of the two sides of the wall is not considered, the displacement of the pipe can be considered.
The rigid waterproof sleeve is suitable for the structure (building) where the pipeline passes through the wall and does not bear the pipeline vibration and expansion deformation, and is suitable for the pipeline passing through the wall with limited space or the pipeline installation prior to the renewal of the structure (building) or pipeline. For areas with seismic fortification requirements, if steel waterproof casing is used, flexible connection shall be set near the pipeline entering pool wall or building outer wall. Type A and type C ductile iron pipes are suitable for ductile iron pipes.
