Introduction to Waterproof Casings: Why simply cementing a pipe into a wall is a recipe for future leaks.
Flexible Waterproof Casings (Type 02S404): Designed for areas with vibration or earthquake risk. Features a rubber sealing ring and pressure plate.
Rigid Waterproof Casings: Best for standard walls where no movement is expected. Cost-effective and durable.
Key Selection Factors: Wall thickness, pipe material, and hydrostatic pressure requirements.
B-NAI’s Manufacturing Standards: We strictly follow the 02S404 national standard for wall thickness and anti-corrosion coating.
