Flexible waterproof casing is generally suitable for structures that are subject to vibration or strict waterproof requirements when the pipeline passes through the wall. After the casing is partially processed, the outer wall is primed once (the primer includes camphor or cold primer) . The waterproof casing is divided into a rigid waterproof casing and a flexible waterproof casing. The two are mainly used in different places. Flexible waterproof sleeves are mainly used in places such as civil defense walls and pools. Rigid waterproof sleeves are generally used in locations where pipes such as basements need to pass through.
Flexible waterproof casing is suitable for the hardware fittings of the structure where the pipeline passes through the wall subject to vibration or strict waterproof requirements. General manufacturers are manufactured according to the S312, 02S404 standard atlas developed by the Institute of Building Science. Flexible waterproof casing wall through the wall, if non-concrete should be replaced with concrete walls, the casing must be solidified in the wall at one time; flexible waterproof casing is widely used in construction, chemical, steel, tap water, sewage treatment, etc. unit.
Rigid waterproof casing is a steel pipe with a wing ring (annular sleeve made of steel plate is placed on the steel pipe), and it is installed in the wall (mostly concrete wall). The outer wing ring, the inner ring and the like are also available. The flange inner wire is sold in sets or can be processed by yourself. It is used for pipelines that require shock absorption, such as pipes connected to water pumps passing through walls.
Both flexible waterproof sleeves and rigid waterproof sleeves are hardware fittings used for pipes to pass through the walls of buildings subject to vibration or strict waterproof requirements, and are often used in construction, chemical, steel, tap water, sewage treatment and other units.
The most intuitive difference between a rigid waterproof sleeve and a flexible waterproof sleeve is that the appearance is different. The flexible waterproof sleeve has a rubber water stop ring inside, such as to prevent water leakage when used in the pool wall. Their installation lengths are different. The standard length of flexible casing is 300mm and the standard length of rigid casing is 200mm. However, they have one thing in common: they can be arbitrarily lengthened or shortened according to the needs of the construction.
