What are the different types of waterproof casings used?

When the pipeline passes through the foundation, interior walls, floors, etc., when the pipeline is used (pressure pipelines, such as water supply, heating, etc.), it will cause disturbance to the building, and at the same time facilitate the installation and maintenance of the pipeline, which is larger than the installation pipeline. The short diameter of the pipe, the material and the length are in accordance with the requirements, and installed in the foundation, the inner wall, the floor and other pipeline crossings.

Ordinary casings are made of welded pipes. The ends of the casings should be mechanically cut (for example, with a toothless saw), and the wall thickness is not strict.

A specially made casing that is installed when the pipe passes through a building or structure that has waterproof requirements such as a basement. Commonly used rigid waterproof casing.

For rigid waterproof casing, it is necessary to weld the waterstop ring outside the casing. The wall thickness of the casing and the wall thickness of the ring are strictly required, and the quality of the weld should be ensured.

The new extended waterproof casing is a long-length waterproof casing made of thickened wall, which can meet the requirements of the ultra-thick wall.

Anti-corrosion waterproof casing, waterproof casing specially treated by anti-corrosion coating, effectively preventing oxidation and corrosion of waterproof casing.
