Abstract: When using raw material tape, pay attention to the number of winding turns. There is no hard and fast rule for the number of winding turns. It is generally based on the thread gap of the pipe fitting and the thickness of the raw material tape material. It can be tightened , as long as it does not leak. Under normal circumstances, it is usually wound around a dozen times. When using raw material tape, it is not good to wrap it too much or too little. Wrapping it too much will not improve the sealing effect, but may cause the pipe fittings to be unable to be installed back. Wrapping it too little will affect the sealing effect and lead to water leakage, so it must be Wrap the appropriate number of turns. Let’s take a look at how many times the raw material tape is usually wrapped. 1. How many turns of raw material tape are generally wrapped?
PTFE raw material tape is usually wrapped around the joints of pipe fittings to achieve a sealing effect. Many friends do not know the specific number of turns, so how raw materials are used? How many turns of tape is appropriate?
In fact, the number of turns to be wrapped with raw material tape is not fixed, because different pipe fittings require different numbers of turns. There is no hard and fast rule for the number of turns to be wound. It is usually based on the thread clearance fit. As long as it can be tightened and there is no leakage, according to experience, it usually takes more than ten turns to ensure the sealing effect.
In addition, the number of times the raw material tape is wrapped depends on the thickness of the material itself. For example, if a faucet is normally wrapped with 10 turns of raw material tape, if a thicker raw material tape is used, it may be wrapped with 8 turns. Enough.
2. What will happen if the PTFE raw material tape is wrapped too much?
When using PTFE raw material tape to wrap a pipe fitting, the specific number of turns depends on the thread gap of the pipe fitting and the raw material tape. Material, when wrapping, the number of turns should be appropriate. Wrapping too much may affect the sealing effect; in addition, if the number of turns is too many, the pipe fitting will be bloated and may not be able to be stuffed in.
3. Will the polytetrafluoroethylene tape leak if it is not wrapped enough?
Yes.
Some friends use raw material tape to wrap pipe fittings for convenience. After wrapping it three or five times, they feel it is good and there is no need to continue wrapping it. However, in fact, this may not achieve a good sealing effect with the raw material tape. , water leakage will occur before long.
