Casings can be divided into
Ordinary casings are centimeters thicker than the pipes to be used and are fixed in the wall or board through which the pipes pass. Flexible casing is a flexible material used to seal the space between the casing and the pipe.

Flexible waterproof casings are generally suitable for structures where pipes pass through walls that are subject to vibration or have strict waterproofing requirements. Rigid waterproof casings are generally suitable for structures where pipes pass through walls and require general waterproofing. Flexible and rigid waterproof casings If the wall where the pipe penetrates is not concrete, it should be replaced by a concrete wall, and the casing must be solidified in the wall at one time.
