How many layers of raw material belts are suitable for sealing connection of water pipe fittings?
When connecting water fittings, there is no hard and fast rule on how many layers of raw material tape is wound, which is subject to tightness and water tightness. However, according to experience, it generally takes more than ten turns to ensure a good sealing effect.
Correct winding method of raw material belt:
1 The connecting parts shall be cleaned of foreign materials.
2 Pay attention to the winding direction. Take the angle valve as an example. When the angle valve is screwed into the thread of the internal thread of the wall, it rotates clockwise to the right. The direction of winding the raw material belt on the angle valve is counterclockwise to the left, so that the angle valve will be tightened and will not be loosened.
3 when winding, the raw material belt should be tightened, so that the raw material belt can be tightly attached to the thread, as tight as possible, and cannot be loosened. After winding, you should press it tightly with a hand ring, or you can press it while winding.
There is no hard and fast rule for winding "several layers", which shall be subject to tightness, but according to experience, it usually takes more than ten turns to ensure the sealing effect.
5 when screwing the thread, don't screw it to death. You don't have to twist it until it can't be twisted, as long as it feels firm when you twist it.
