What is a Rigid Waterproof Casing

I. Rigid waterproof casing is manufactured based on the drawings of the AW1 type steel loose flange waterproof casing (updated standard) developed and designed by the Building Science Research Institute. It is suitable for use with cast iron pipes, concrete pipes, or steel pipes as casing.

II. In pipeline construction through underground exterior walls, rigid waterproof casing is used to prevent pipelines from being affected by groundwater pressure and chemical corrosion in the soil.

III. The role of waterproof casing in pipeline construction:

1. Waterproof casing is suitable for cast iron and steel pipelines, as well as other shapes or materials of pipelines passing through walls.
2. Rigid waterproof casing is a category of flexible waterproof casing, available in various types and specifications.

IV. Characteristics of rigid waterproof casing:

In areas with high groundwater levels, rigid waterproof casing is used to prevent external water from penetrating indoors when pipelines passing through walls come into contact with water.

V. Materials of rigid waterproof casing:

Rigid waterproof casing is generally made of steel pipes, and some are welded from steel plates. The flange inner cavity is filled with flexible filler, providing a waterproof function.
