Raw material tape is not wrapped more sealed before good, raw material tape wrapped how many rings need to be in accordance with the thread clearance. After wrapping the raw material belt, also needs to pay attention to the tightening strength. According to the feedback from the master, first tighten the thread fittings by hand, and then use the pipe pliers to screw in 0.5-2 turns. And the amount of twisting and twisting required, it depends on the standards of the pipe. After winding, we can tear it by hand. At this time, we can tighten the screw fitting or nut. Now the raw material belt produced by the factory is very convenient to use. Raw material tape is used to seal pipe joints, so that the pipeline is better sealed, sometimes also used in plumbing installation works. But a lot of times, everyone will say, wrapped in a dozen rings of raw material Belt Faucet, why leak. Most of the reasons are due to the wrong way of winding the raw material belt. Analysis: First, the raw material belt needs to be wound in the direction of the thread, and the sealing performance is greatly reduced if it is wound in the opposite direction In addition to avoiding the raw material into the pipeline, will also reduce the sealing performance. It is recommended that the first filament be left out by winding the second filament at the beginning of the thread. 3: The raw material belt needs to be wound with a little force to ensure that the raw material belt is not broken This way the raw material wrapped out of the belt is tight and strong enough to ensure sealing.
