Introduction: In the case of manufacturing waterproof casing, material selection is a more important stage, in the material level, material thickness level need to be tested. First of all, the selection of materials in the case of carbon steel and stainless steel selection, the general application of carbon steel, but in the

Making Waterproof casing Material selection is an important stage, which needs to be tested at the material level and thickness level. First of all, when selecting materials, we need to choose between carbon steel and stainless steel. Generally, we use carbon steel. However, in some areas, carbon steel has a very bad environment. Even if carbon steel is painted, it can not resist strong acid and alkali erosion. Therefore, in some cases, we will use stainless steel to make waterproof casing.
Flexible waterproof casing The key is composed of short pipe, wing ring, retaining ring, rubber ring, gland and bolt nut. The rubber ring with rubber material has sealing effect. According to the obvious extrusion of gland and short pipe, the rubber ring is deformed, resulting in stronger sealing effect. Therefore, the installation area of flexible waterproof sleeve is mostly in the wall and the wall with strict sealing regulations.
Rigid waterproof casing The key is composed of short pipe, wing ring and retaining ring. Without the mutual cooperation of rubber ring, the rigid waterproof sleeve is sealed according to the filling material, and the sealing effect is ordinary compared with the flexible waterproof casing. Therefore, most of the rigid waterproof casing is used to maintain the stability of the pipeline and its route across the wall.
Customers often call to ask where flexible and rigid waterproof casing are used respectively? Let's take a look at where these two kinds of waterproof casing are installed.
Flexible waterproof sleeve is a kind of hardware fittings for buildings with vibration or strict waterproof regulations where the pipeline crosses the wall. The general manufacturers are manufactured according to S312 and 02s404 standard atlas developed and designed by the Architectural Science Research Institute.
The rigid waterproof sleeve is suitable for the structure (building) where the pipeline passes through the wall without bearing the pipeline vibration and expansion deformation, and is suitable for the transformation of the pipeline with limited space or the pipeline installation lies in the structure (building) or pipeline. If rigid waterproof casing is selected in the area with earthquake protection regulations, flexible connection shall be set near the pipe entering the side wall or building wall. Type A is suitable for steel pipe, type B and type C are suitable for ductile cast steel pipe and cast iron pipe.
