Introduction: For the manufacturers of embedded flexible casing, the development of waterproof casing industry is too much dependent on the stimulation brought by the development of downstream industry. From the development mode of waterproof casing industry, the opening up of new market and the innovation of new technology application are aimed at the development of waterproof casing industry

Manufacturer of embedded flexible casing, Waterproof casing The development of the industry relies too much on the boost brought by the development of downstream industries. From the perspective of the development mode of the waterproof casing industry, it is necessary to open up new markets and innovate the application of new technologies for the development of the waterproof casing industry. In addition, the implementation can not be completely separated from the boost brought by the development of downstream industries. We should be calm and innovative and open up new markets. Flexible waterproof casing Different from the area used for civil air defense sealing sleeve, the flexible waterproof sleeve is integrated into the structure with vibration or tight waterproof requirements where the pipeline crosses the wall. Refer to 02s404. Civil air defense sealed sleeve is used to pass through civil air defense area. Flexible connection is used between flexible waterproof casing and pipeline, and rigid connection is selected for civil air defense sealing sleeve.
Generally, the raw material of flexible waterproof casing is Q235-A carbon steel, but when it comes to the chemical plant pipeline and corrosive material pipeline, the general raw material waterproof casing can not meet the application requirements. At this time, customers are recommended to use stainless steel raw material waterproof casing. For the corrosion resistance and heat resistance of stainless steel raw material, the general chemical plant pipeline can meet the application requirements. The choice of stainless steel raw materials, 304 is a practical stainless steel, 304 stainless steel has stainless steel corrosion resistance and good stress corrosion resistance. Naturally, if the requirements are more strict, 316L stainless steel can also be used to produce waterproof casing. 316L has excellent corrosion resistance, air corrosion resistance and high temperature compressive strength due to the addition of mo. flexible waterproof casing can be applied under harsh standards Rigid waterproof casing The exterior is painted to look good, while the inside is painted to prevent rust. Generally, the outside of the waterproof casing is not painted according to the mark. Flexible waterproof casing is not well integrated with concrete when painting. Sometimes customers require no spraying. The advantage of not spraying outside is to make the waterproof sleeve more integrated with concrete. The interior of Linyi flexible waterproof sleeve needs to be painted with anti-corrosion paint, but today's production From a good-looking point of view, both inside and outside are painted.
The thickness of concrete wall of flexible waterproof casing at the place where it passes through the pipe shall not be less than 300 mm, otherwise it shall be thickened on one side of the wall or on both sides. The diameter of type D6 should be thicker than that of type D6. The net weight of raw materials of waterproof casing is calculated according to the wall thickness L value of 300 mm. If the wall thickness exceeds 300 mm, it shall be measured again. The welding material of waterproof casing component is made of A3 raw material and welded by T42. The flexible waterproof casing is generally made according to the building standard atlas. The length of the waterproof sleeve required in the atlas is the same as the wall thickness. Therefore, the flexible waterproof sleeve is the same as the wall thickness. The flexible waterproof sleeve with strict waterproof requirements will leave a flange surface than the wall thickness.
