What are the specifications for the installation of threaded rubber expansion joints?
Threaded rubber expansion joints are widely used for removable fixed connections compared to flange and receiver connections. When installing, the pipe fittings at both ends to be connected should be placed on a level surface first, and the threaded structure needs to be screwed into the lifting section of the pipe fittings first, and then the other section of the pipe fittings, please always keep the level surface to prevent the rubber expansion joint from tearing due to uneven force during installation, and then the pipe fittings at both ends should be fixed by hand or wrench on an object that is not easily stretched or twisted. According to different flow requirements and pressure-bearing requirements, the selected water pipe outer diameter is also different. In order to meet different pressure-bearing requirements, there are different series of water pipes under the same outer diameter. Both can reduce vibration and noise, and can play a compensating role for thermal expansion and contraction caused by temperature changes, and are widely used in various pipeline systems. Because the threaded rubber expansion joint has good comprehensive performance, so it is widely used in chemical industry, construction, water supply, drainage, petroleum, light and heavy industry, refrigeration, sanitation, plumbing, fire protection, electric power and other basic engineering. For example: connection with pumps and valves, pipelines with high vibration, pipelines with frequent changes of heat and cold, etc.
