The protective closed casing type B is suitable for general pipelines to pass through the wall. The space where the pipeline passes through the wall is limited or the pipeline installation is prior to the renovation of the structure (construction) or pipeline.
It is used for the water supply and drainage system to pass through the wall of the anti-control basement to effectively prevent leakage and pollution of the air to prevent damage to the basement.
