Flexible waterproof casing sealing rubber ring is essential
Flexible waterproof casing is an essential pipeline system construction infrastructure work in the pipeline accessories products, flexible waterproof casing can play a tight waterproof role, and in the appropriate earthquake or foundation sinking can effectively protect the pipeline from damage, the quality of the selection of flexible waterproof casing is also very important.
 
Flexible waterproof casing composition of the main components of the rubber seal, Henan Huanxin Water Supply Equipment Co., Ltd. production of flexible waterproof casing sealing ring materials commonly used for: nitrile rubber, neoprene, fluorine rubber three. Rubber rubber ring hardness should reach: Type I: 50 ± 5 degrees, Type II: 70 ± 5 degrees. Flexible waterproof casing sealing rubber ring physical properties should be in line with the requirements of HG/T3091: 2000 standard. Flexible waterproof casing sealing rubber ring should be free of air bubbles, there should be no surface defects or unevenness that can affect its use performance. Flexible waterproof casing sealing rubber ring should be molded, when the production of large seals need joints, the interface angle of 30-45 °. The wrong side should be less than 2% d, the interface should be strength test, such as failure should be reconnected. Our normal project use for Ⅰ type double round seal rubber ring, such as special tight waterproof requirements of the use of the environment should be selected type II seal rubber ring (conical rubber ring). In addition, when accepting the waterproof casing should also check whether the waterproof casing rubber ring is damaged. Flexible waterproof casing sealing rubber ring due to the simple structure, good sealing resistance, sealing structure is small, easy to disassemble, small friction resistance of movement, can play a two-way sealing role and other advantages, is widely used in oil pressure, air pressure, water pressure static and dynamic sealing, for dynamic sealing, small diameter flexible waterproof casing seal using pressure mold overall pressing, as a basic accessory mass production to support the flexible waterproof Casing supply market.
