Performance characteristics of flexible sleeve expansion joint.
Flexible sleeve expansion joint can be axially expanded and contracted within a certain range, and can also overcome the offset produced by different axes of pipeline docking within a certain angle, which can greatly facilitate the installation and disassembly of valve pipelines, and can be freely expanded and contracted in the allowable expansion amount of pipelines, and will play a limiting role once it crosses its expansion amount to ensure the operation of pipelines. The service life of flexible sleeve expansion joint is long and the fatigue life is comparable to that of the pipeline. The sliding surface is specially treated and has good corrosion resistance in salt water, salt solution and other environments. Meanwhile, when the sealing effect is weakened due to wear and tear after many years, the flange can be tightened again to enhance the sealing performance. Flexible sleeve expansion joint has no requirement for chloride ion content, which is especially suitable for the system where the medium or surrounding environment exceeds the chloride ion standard. Detailed description of flexible sleeve expansion joint. Flexible sleeve expansion joint for various water supply and drainage pipelines, water towers. The installation and disassembly of water pump, water meter and valve provide great convenience, and play a good role in regulating the expansion and contraction of long distance pipelines due to temperature difference. Flexible sleeve expansion joint The pipe within the product is divided into three kinds: cast iron, galvanized and steel. The working pressure is PN6, PN10 and PN16. Before installation, the flexible sleeve expansion joint should be loosened from the pressure plate bolt, pulled to the installation length, then tightened diagonally, do not press the deviation, such as overhead use, both ends must be installed the corresponding fixed bracket.
