Introduction: Flexible waterproof casing can be widely used in all kinds of engineering construction, underground pipeline through the wall, civil air defense engineering, and can be comprehensively treated in four forms. Our factory will hear the customer's response about the diameter and size of the waterproof casing ordered. Here we will explain the waterproof casing according to 02s404

flexibility Waterproof casing It can be widely used in all kinds of engineering construction, underground pipeline through the wall, civil air defense engineering, and can be comprehensively treated in four forms. Our factory will hear the customer's response about the diameter and size of the waterproof casing pipe ordered. Here, we need to explain the waterproof casing, and take it according to the 02s404 atlas Flexible waterproof casing It can be divided into gland inner diameter, casing inner diameter, outer diameter and inner diameter.
What we usually say is the nominal diameter, that is, the model. If we need to compare the product size, that is, the inner diameter of the pipe is 100 mm, and the thickness of the steel pipe with the inner diameter of 100 mm is 4 mm according to the regulations, so the outer diameter of the pipe is 108 mm, and then it needs to be penetrated into the waterproof sleeve. If the inner diameter of the gland is 108 mm, it will be difficult to pass through the pipe, so the inner diameter of the gland should be compared with The outer diameter of the tube is several millimeters larger, so the inner diameter of the gland is specified to be 114mm.
Therefore, this is why the nominal diameter of flexible waterproof casing is smaller than the inner diameter of gland, which is also the design standard for easy steel pipe crossing after installation and convenient maintenance in later stage. It is also a convenient and practical reason for gradual research and improvement on the problems encountered and application effect problems over the years, which makes it convenient and practical and can protect the pipe and wall from damage Because.
In addition, the standard of flexible waterproof casing lengthening is DN300. However, due to different engineering requirements, the standards adopted are also different. For example, the diameter below DN300 is used in high-rise buildings. If it is larger than 300 mm, the manufacturer can not make it in advance. Therefore, it is not sufficient in the supply of goods, so it should be customized and processed. It should be lengthened or enlarged according to the needs of the project The standard is still made by 02s404 atlas.
The production of waterproof casing products requires the use of finished steel materials, welding rods, flexible aprons, etc. when entering the factory, they need to go through strict sampling inspection, and each supplier is required to provide the corresponding product certificate and quality inspection report. The quality of products is inseparable from the quality of raw materials Grab it. All users who purchase waterproof casing products know that the product is welded at the designated position in the wall steel frame first, and then concrete pouring is carried out, because such products need to be installed in the concrete wall. If the non concrete wall needs to be concreted, the local part of the installation position of the waterproof sleeve needs to be concreted and the part needs to be thickened.
