When a flexible waterproof casing fails, in order to ensure the normal operation of the system, a bypass device is installed. When the flexible waterproof sleeve is installed in the branch, the diameter of the flexible waterproof sleeve should be smaller than the diameter of the flexible waterproof sleeve door of the main pipe.

Flexible waterproof casing. The waterproof effect of flexible waterproof casing is better than that of rigid waterproof casing, so it is suitable for parts with strict waterproof requirements, or for wall-through pipes where walls are vibrated. The production of flexible waterproof casing must be strictly based on the requirements of the S312 and 02S404 standard drawings. The common flexible waterproof casing structure is shown in Figure 1.
