DN2000 waterproof casing flexible waterproof casing rigid waterproof casing

There is a back-up ring at the other end of the waterproof casing pressure plate, and a back-up ring is added at the other end of the pressure plate. When selecting the type and type, the selection rules should be followed. If the general sealing requirements are required, the type should be selected, and the tight sealing requirements can be selected. type because it has a fit. Pay special attention to the fact that when the temperature exceeds the use range, the sealing material and product material will be investigated accordingly. The dimensions should comply with the national standard drawings as much as possible. If the size used needs to be adjusted, please make a special request. We will refer to the national standard drawings to carry out appropriate design and production. Please provide the specific size of the wing ring used, which can be processed according to actual requirements. The installation of waterproof casing should follow the installation rules as much as possible. If the actual situation does not allow it, please design according to the actual use environment. If there are corrosion resistance requirements, the corresponding materials must be selected for the corrosion requirements. Waterproof casing is divided into rigid waterproof casing and flexible waterproof casing. Rigid waterproof casings are mainly used in general construction projects, mainly in buildings that do not require high waterproofing, such as septic tanks, pools, basements, etc. The waterproof casings are pre-embedded into the wall during construction and are installed in the plumbing system. When passing the pipe through it, the casing is filled with flexible waterproof sealing material between the pipes. Filling materials mainly include asphalt fiber, vinyl foam board, etc. Generally, the wall-penetrating length of waterproof casing is. For walls with special requirements, it can be lengthened. The specific length of extended waterproof casing can be processed according to drawings. The composition of waterproof casing. Rigid waterproof casing mainly consists of steel pipes and external wing rings, which are generally larger than the through pipes. The waterproof wing ring has the same structure as the rigid waterproof casing. Flexible waterproof casing mainly consists of flexible waterproof casing except for the outer wing ring and the inner part. There are also retaining rings and flange inner wires, which are sold in sets, or you can process them yourself. They are used for pipelines that require shock absorption, such as when pipes connected to water pumps pass through walls. Flexible waterproof casing can slow down the impact of pipeline vibration on the wall, ensure that the wall is strong and reliable, and there are no gaps between the walls and the sealing is firm.
