Waterproof casing waterproof casing choice _ _ Gongyi Hua Yang pipeline selection techniques

How winter should choose to install a waterproof casing waterproof casing after we buy, we want longer service life. So, how to extend the life of waterproof casing it? 1, the use of this product is suitable for residential, general industrial, municipal water supply and drainage structure (building) buildings. 2, classification application form waterproof casing structure is divided into flexible waterproof casing (A / B tube), rigid waterproof casing (A / B / C type) and three types of rigid waterproof wing ring. 3, flexible waterproof casing is applied to the earthquake area requirements, through the wall of the pipe to withstand vibration and stretching deformation of piping, exterior walls or structures strict water requirements. Ⅰ-rings for general water requirements, type Ⅱ apply more rigorous water requirements. Temperature range, -20 ℃ ~ + 80 ℃. When the wall pipe is connected to the pump or pressurized equipment into and out of the pipeline, it is desirable to set flexible joint at the junctions. 4, rigid waterproof casing pipe through the wall at a suitable pipe is not subjected to vibration and stretching deformation of the structure (building) buildings. For seismic fortification areas, such as the use of rigid waterproof casing, flexible connectors should be set up on a nearby wall or building facades into the pipeline. A type is suitable for steel, B, C is suitable for ductile iron pipe and cast iron pipe. 5, rigid waterproof casing pipe through the wall at a suitable pipe is not subjected to vibration and stretching deformation of the structure (building) buildings. For seismic fortification areas, such as the use of rigid waterproof casing, flexible connectors should be set up on a nearby wall or building facades into the pipeline. A type is suitable for steel, B, C is suitable for ductile iron pipe and cast iron pipe. . Such as the use of rigid waterproof wing ring flexible connection should be set up on a nearby wall or building facades into the pipe, A is suitable for steel pipes. DN1500 parameters 02S404 flexible waterproof casing waterproof casing above the flexible waterproof casing portfolio is the largest model DN1000 and DN1000 and rigid waterproof casing over there DN1200,1400,1600,1800,2000. DN1000 is greater than the actual production of flexible waterproof casing generally in accordance with the same type of rigid waterproof casing wear tube diameter do, and wing ring, tube thickness is slightly larger than DN1000. But DN1500 flexible waterproof casing that according to what criteria do? Because there is no rigid waterproof casing part DN1500 parameters. In this case only in accordance with the actual pipe diameter design and production, 1520 DN1500 pipe diameter, and therefore made out of flexible waterproof casing diameter must be greater than 1520, but not too big. The actual production casing diameter is generally to do by 1530, so wear tube 1520 without any problems.
