Introduction: Rigid waterproof casing and flexible waterproof casing belong to through wall casing, that is, through wall casing, so they are generally installed at the position where the pipe needs to pass through the wall. Rigid waterproof casing and flexible waterproof casing are used in different areas

rigidity Waterproof casing And Flexible waterproof casing In general, the casing pipe is installed in the wall through position. Rigid waterproof casing Different from flexible waterproof casing, flexible waterproof casing is mainly used in areas with high requirements such as civil air defense wall and pool; rigid waterproof casing is generally used in basement and other places where pipelines need to pass through the wall.
S30212 is designed and manufactured according to the standard of s30212. The wall where the flexible through wall waterproof sleeve passes through the wall should be changed into concrete wall if it is not concrete, and the casing must be condensed in the wall at one time; the flexible through wall waterproof casing is widely used in construction, chemical plant, steel, drinking water, wastewater treatment and other enterprises.
Rigid through wall waterproof casing is steel pipe with flange ring (steel plate ring is sheathed on steel pipe), which is installed in the wall (see concrete wall) to pass through the wall, which is conducive to the waterproof of wall. In addition to the external wing ring, the flexible through wall waterproof casing also has flange inner thread such as retaining ring, which can be sold by complete set of equipment and can be processed by itself to meet the requirements of shock absorption When the pipe connected with centrifugal pump passes through the wall.
No matter flexible through wall waterproof casing or rigid through wall waterproof casing, all hardware fittings are used for pipeline to pass through the building wall with vibration or strict waterproof requirements. It is commonly used in construction, chemical plant, steel, drinking water, wastewater treatment and other enterprises.
When the pipeline passes through the shear wall foundation, beam and special-shaped column of concrete structure, it shall be installed together with the civil engineering. The reasons are: after the holes are embedded, the secondary pouring between the casing and the concrete is not easy to solve; some cannot be handled, such as installing rigid through wall casing on the concrete shear wall of basement foundation.
