1. How many laps are usually wrapped around the raw material belt

The polytetrafluoroethylene raw material tape is generally wound around the joint of the pipe fittings to achieve a sealing effect. Many friends do not know the specific number of turns, so how many turns of the raw material tape are appropriate?

In fact, it is not fixed how many turns the raw material tape needs to be wound. Because the pipe fittings are different, the number of turns that need to be wound is also different. There is no hard and fast rule for the number of turns to be wound. There is no leakage. According to experience, it is generally necessary to wrap more than ten turns to ensure the sealing effect.

In addition, the number of turns of the raw material tape depends on the thickness of the material itself. For example, for a faucet that is normally wrapped with 10 turns of raw material tape, if a thicker raw material tape is used, it may be enough to wrap it 8 times.

When using PTFE raw material tape to wrap pipe fittings, the specific number of turns depends on the thread clearance of the pipe fittings and the material of the raw material tape. When wrapping, the number of turns should be appropriate. Too much wrapping may affect the sealing effect. Too many laps and the fittings will be bloated and may not fit in.

3. Will the PTFE tape leak less if it is wrapped less?

  meeting.

When some friends use raw material tape to wrap pipe fittings, the drawing is convenient, and they feel good after three or five turns, so there is no need to continue wrapping them. water leakage.
