DN146 waterproof casing 02S404 flexible waterproof casing rigid waterproof casing

Considering its shrinkage when operating in outdoor environments, the waterproof casing must be fixed with pressure strips and nails.
When working in outdoor environments involving flexible waterproof layers, due to the shrinkage of the waterproof layer and the action of rain and wind, the waterproof casing often warps and delaminates in advance, leaking before the large-surface waterproof layer. Therefore, the specification stipulates that the closing end of the coil must be fixed with battens and nails, and then sealed with sealing material to reserve a groove at the brick flashing area. The closing end is pressed into the groove, and then cement mortar is used to protect the concrete water treatment. The upper part of the closing end is If you want to use coiled material or metal to cover the end of the protective coating, it is required that each coating layer be staggered and cannot be concentrated in one place.
If the environment is special, such as a corrosive environment, we can consider using stainless steel waterproof casings. Our company also produces such casings, and the company has sufficient stocks. If special customization can be made, an appointment can be made in advance. At the same time, if it also involves the installation of water and electricity, at this time we should install the rigid waterproof casing | The waterproof casing atlas is a steel pipe with a wing ring installed in the wall for general pipes to penetrate the wall, which is beneficial to the waterproofing of the wall. In addition to the flexible waterproof casing The external wing ring and internal flange wires such as retaining rings are sold in sets or can be processed by yourself. They are used for pipelines that require shock absorption, such as when pipes connected to water pumps pass through walls.
If you only consider the penetration of the pipe through the wall, without considering the waterproof performance of both sides of the wall and the displacement and deformation of the pipe after passing through the wall, you can choose a rigid waterproof casing. In other words, if you consider the waterproof performance of both sides of the wall, you must use flexible waterproof casing | Waterproof casing atlas. All in all, we must consider waterproofing when passing through walls. Avoid losses caused by later engineering modifications.
Rigid waterproof casing is used to solve the problem that some underground projects require pipelines to pass through walls, and there are strict waterproofing requirements at the passing points. Some structures also need pipelines to pass through walls. At the same time, the pipelines are restricted from being affected by temperature changes. It is designed and manufactured to prevent expansion, contraction and displacement caused by changes or external forces, and not to allow the pipeline to vibrate under the action of external factors. The outer shell of the rigid waterproofing sleeve is cast onto the wall in one go.
