S312 Flexible Waterproof Casing Coupling 02s404

Flexible waterproof sleeve is suitable for the metal pipe that the pipe passes through the wall where there is vibration or the structure with strict waterproof requirements. The wall where the flexible waterproof casing goes through the wall shall be changed to concrete wall if there is no concrete. Flexible waterproof casing is widely used in construction, chemical industry, steel, water, sewage treatment and other units.
When the pipeline crosses railway lines, roads, streets and other places, protective casing is installed outside the pipeline to prevent the pipeline from being crushed under the load. For example, large diameter concrete pipe, large diameter steel pipe and other measures are adopted to avoid external forces (load) acting directly on the outer wall of the pipeline, resulting in pipeline damage.
Waterproof casing is also called through wall casing, through wall pipe. Flexible waterproof sleeve is generally suitable for structures where pipes pass through walls and are subject to vibration or strict waterproof requirements. After partial processing of the casing, the outer wall of the casing is covered with primer (the primer includes 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 waterproof bushing is mainly used in places with high requirements, such as the air defense wall and the pool, while rigid waterproof bushing is generally used in places where pipes, such as basement, need to go through pipes.
