DN690 waterproof casing flexible waterproof casing rigid waterproof casing

The requirements for the width of the wing ring of the flexible waterproof casing are designed to meet national unified standards, and there are national standards and non-standard factory standards. However, no matter which standard is adopted, the cutting and processing must be carried out according to the dimensions specified in the atlas to meet the usage standards. Professional manufacturers can make special customizations according to different requirements of construction projects. What determines the width of the wing ring of a rigid waterproof casing? In the waterproof casing atlas, the diameter of the wing ring minus the diameter of the casing is divided directly to get a rigid waterproof casing. The width of the wing ring. Take the rigid waterproof casing as an example, the outer diameter of the wing ring is, and the outer diameter of the casing is directly divided by the outer diameter of the wing ring minus the outer diameter of the casing. The national standard has unified sizes, and there is also a factory standard, which is developed by the manufacturer according to the requirements of the project. The width and thickness of the water stop ring and the pipe thickness of this standard are slightly different from the national standard, but they will all be based on customer needs, for example Save the budget, but even so we will produce it with absolute guarantee of quality. For example, the water stop ring of conventional rigid waterproof casing products is set in the middle position, while some need to be set close to a centimeter. Some need to be lengthened for thicker walls, and wing rings are added according to the actual lengthening. The wing ring width of this product is determined according to the product standard. The wing ring thickness of the rigid waterproof casing is specially marked in the waterproof casing atlas. The thickness of the wing ring is: wing ring thickness is: wing ring thickness is: wing ring thickness is: wing Ring thickness is thick.
