What is Rigid Waterproof Casing
Rigid waterproof casing is a protective device used to prevent water seepage when pipes pass through walls or floors. They are widely used in construction, municipal administration, chemical industry and other fields. It is embedded in the concrete structure to form a rigid seal, effectively preventing the penetration of water, gas or impurities and ensuring the safe operation of the pipeline system.
Characteristics of rigid waterproof casing
Rigid waterproof casing has the following characteristics:
| Features | Description |
|---|---|
| High strength | Made of high-quality steel or cast iron, strong pressure resistance |
| Good sealing | Leak-free connection via welding or flange connection |
| Corrosion resistant | The surface is anti-corrosion treated and suitable for use in humid or corrosive environments |
| Easy to install | Pre-embedded design reduces the difficulty of later construction |
Classification of rigid waterproof casing
According to different structures and uses, rigid waterproof casing can be divided into the following categories:
| Type | Applicable scenarios |
|---|---|
| Type A | Ordinary through-wall waterproofing, suitable for general buildings |
| Type B | With water stop ring, suitable for areas with high waterproof requirements |
| Type C | Flange connection type, suitable for chemical or high-pressure pipelines |
Application fields of rigid waterproof casing
Rigid waterproof casing is widely used in the following scenarios:
| field | Specific applications |
|---|---|
| construction project | Waterproof areas such as basements, bathrooms, and kitchens |
| Municipal Engineering | Underground pipe networks, tunnels, bridges, etc. |
| Industrial field | Chemical plants, power plants, sewage treatment plants, etc. |
Installation steps of rigid waterproof casing
In order to ensure the waterproof effect, the installation of rigid waterproof casing needs to follow the following steps:
| steps | Operation content |
|---|---|
| 1. Positioning | Determine the casing position according to the design drawings |
| 2. Buried | Fix the casing in the formwork and pour the concrete |
| 3. Pipe installation | After the concrete has solidified, insert it into the pipe |
| 4. Sealing treatment | Use waterproof glue or sealing rings to fill gaps |
Precautions when purchasing rigid waterproof casing
When purchasing rigid waterproof casing, you should pay attention to the following points:
| Things to note | Description |
|---|---|
| Material selection | Choose carbon steel, stainless steel or cast iron depending on the environment |
| size match | Make sure the inner diameter of the casing is larger than the outer diameter of the pipe |
| Waterproof level | Choose type A, type B or type C according to project requirements |
| Brand reputation | Give priority to manufacturers with quality certification |
