In order to meet different pressure-bearing needs, there are different series of water pipes with the same nominal outer diameter. The threaded rubber joint installed on the pipe is a highly elastic, airtight, media and weather resistant pipe joint. The threaded rubber joint has the characteristics of medium resistance, vibration and noise reduction. When the product is used in hot water pipeline, the pipe fittings at the two ends to be connected should be placed on a horizontal surface and leveled first.
When installing a threaded rubber joint in a hot water pipe, the two ends of the pipe should be placed on a horizontal surface and leveled. The next step is to tighten the nut by hand or wrench to secure the threaded rubber joint and the two ends of the fitting to an object that does not stretch or twist easily. The threaded rubber coupling needs to meet both the flow and pressure requirements of the water pipe. In order to meet different flow requirements, engineers designed different nominal outside diameters of water pipes, so there are 20mm, 25mm, 32mm and other outside diameters of water pipes.
