Waterproof casing specification waterproof casing specification
The waterproof casing is also called a wall casing and a wall pipe. The flexible waterproof casing is generally suitable for structures with vibration or tight waterproofing requirements when the pipeline passes through the wall. After the casing is partially processed, the primer is applied to the outer wall (primer includes 樟丹 or cold base oil) . The waterproof casing is divided into a rigid waterproof casing and a flexible waterproof casing. The two are mainly used in different places. The flexible waterproof casing is mainly used in places where the human defense wall and the pool are in high demand. The rigid waterproof casing is generally used in the basement and other pipelines where the pipeline is required to be piped.
The flexible waterproof casing is a hardware fitting suitable for structures with vibration or tight waterproofing requirements when the pipeline passes through the wall. The general manufacturer is manufactured according to the S312 and 02S404 standard atlas developed by the Institute of Building Science. The flexible waterproof casing penetrates the wall of the wall. In the case of non-concrete, the concrete wall should be replaced. The casing must be solidified once in the wall. The flexible waterproof casing is widely used in construction, chemical, steel, tap water, sewage treatment, etc. unit.
The rigid waterproof casing is a steel pipe with a wing ring (the ring made of steel plate is placed on the steel pipe) and is installed in the wall (mostly a concrete wall). It is used for the general pipe to pass through the wall, which is good for waterproofing the wall, and the flexible waterproof casing is except The outer wing ring, inside the ring, and the like, the inner wire of the flange, which is sold in sets, can also be processed by itself, and used for the pipeline with the need for shock absorption, such as when the pipe connected with the water pump passes through the wall.
The most intuitive difference between the rigid waterproof casing and the flexible waterproof casing is different in appearance. The flexible waterproof casing has a rubber water stop inside, such as preventing water leakage when used in the pool wall. Their mounting lengths are different. The standard length of flexible bushings is 300mm and the standard length of rigid bushings is 200mm, but they all have in common that they can be lengthened or shortened according to the needs of construction.
