Waterproof casing atlas 02s404 Flexible waterproof casing Rigid waterproof casing

The waterproof casing is too large for the pipe:
Many customers will ask this question. The technical parameters of the pipe with waterproof casing are determined according to the installation dimensions of the customer's project.
Flexible waterproof casing is generally suitable for structures where the pipe passes through the wall and is subject to vibration or has strict waterproofing requirements.
After the casing part is processed, apply primer on the outer wall (primer includes camphor or cold base oil). The anti-corrosion of the outer layer is determined by the design.
For the wall where the casing passes through the wall, if it encounters a non-concrete wall, a concrete wall should be used instead. The concrete pouring range should be larger than the diameter of the wing ring (), and the casing must be poured into the wall.
The thickness of the concrete wall where the pipe passes should be no less than that of the pipe. Otherwise, the wall should be thickened on one side or both sides. The minimum diameter of the thickened part should be larger than the diameter of the wing ring ().
The material weight of the casing is calculated based on the wall thickness. If the wall thickness is greater than the wall thickness, it should be calculated separately.
