PRODUCT PARAMETERS
The Waterproof Casing (also known as Wall Penetration Casing or Embedded Casing) is a core protective and water-blocking component in pipeline systems when pipes pass through building walls (e.g., basements, pools, external walls). It is mainly classified into rigid and flexible types.
Its primary functions are to secure the wall-penetrating pipeline, prevent wall cracking caused by pipe vibration, and block water seepage paths via water-stop rings or rubber sealing rings, thus avoiding leakage. It is an indispensable embedded part in water supply & drainage, municipal, and industrial building projects.
Application Fields: Widely used in municipal engineering, high-rise buildings, underground garages, wastewater treatment plants, petrochemical complexes, power station pump rooms, water plant pools, and metallurgy & mining projects. Suitable for embedding pipelines such as water supply, drainage, fire protection, and industrial process pipes through walls—especially for underground and humid environments requiring waterproofing, anti-seepage, and vibration protection.
