waterproof casing

The distance between the two flanges, that is to say, the flanges at both ends of the flexible waterproof casing need to be exposed when pre-embedded. Therefore, the so-called Sanqi wall refers to the taller wall. Lanxiang's 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 general waterproofing is required where pipes penetrate walls. Flexible and rigid waterproof casings penetrate walls. , if non-concrete walls are encountered, concrete walls should be used instead, and the casing must be solidified once and the waterproof casing inside the wall is suitable for construction, chemical industry, steel, tap water, sewage treatment and other units.
Rigid waterproof casing is a steel pipe with a wing ring (a ring made of steel plates is installed on the steel pipe and inside the wall (mostly concrete walls are used for general pipes to penetrate the wall), which is beneficial to the waterproofing of the wall. Flexible and rigid waterproof casings are mainly They are used in different places. Flexible waterproof casings are mainly used in civil defense walls, pools and other places with high requirements. Rigid waterproof casings are generally used in basements and other locations where pipes need to pass through. Pipes entering homes from underground pass through buildings. Rigid waterproof casings need to be installed on exterior walls. The casings that penetrate walls (pools, slabs, etc.) are divided into two types: rigid and flexible. After installation, flexible ones are allowed to have deformation, and rigid ones are not allowed to deform.
