How to wrap raw tape, raw tape wrapping tips correctly

Prepare materials: faucet, raw tape.

1. First, put the thread end of the raw tape on the faucet, and then press the thread with your fingers.

2. Tighten the raw tape after compression, and then wrap it 15 to 20 times.

3. Pinch the raw tape tightly with your hands when winding to the halfway point.

After 20 laps, cut the raw tape and pinch the thread tightly by hand.

5. Done. <>

Raw tape correct winding method:

1. First of all, bring the raw meal.

Remove the foreign body from the connection part;

2. Pay attention to the winding direction to the angle valve.

For example, when the angle valve is screwed into the inner wire thread in the wall, it rotates clockwise to the right, so the direction in which we wrap the leftover tape on the angle valve is to the left counterclockwise, so that when the angle valve is screwed, it will be tighter and tighter, and it will not loosen.

3. When winding, the raw material belt should be tightened, so that the raw material belt is tightly attached to the thread, as tight as possible, do not wrap loosely, and press it tightly by hand after winding, or you can wrap it while pressing.

4. There is no hard and fast rule as for winding "several layers", which can be tightened and does not leak, but according to experience, it usually needs to be wound more than ten times to ensure the sealing effect.

5. Don't screw the thread to death, it doesn't have to be screwed until it can't be screwed, as long as the feel can be strong when screwing. In addition, it is necessary to pay attention to the depth of screwing, such as the two bent feet of the cold and hot water mixing valve, and pay attention to keeping the distance out of the wall consistent when screwing, especially when the depth of the two inner wire elbows in the wall is inconsistent.

Rotate the wrap clockwise (at least 10 layers) and screw the fitting into place all at once, without reversing.

Follow the opposite direction of the thread so that the cap is twisted correctly.

Raw meal beltThe correct winding tips are as follows:

1. The raw material belt needs to be wound along the thread direction.

2. Start winding from the second silk tooth and leave the first silk tooth.

3. When winding the raw material belt, you need to use a little force to ensure that the raw material belt is not wound when it is not broken, that is, it is tight and firm, and the sealing is good.

4. The second half of the winding raw material belt is thicker, that is, the front is thin and the back is thick, so as to ensure that the thread is tightened more and more.

5. Do not retract the threaded pipe after tightening, otherwise it needs to be rewound and tightened.

It is mainly used at the interface connection of cold and hot water supply pipe fittings, to enhance the tightness of the pipeline connection, to prevent the interface from leaking, to increase the leakage prevention effect of the interface, and to use raw meal belts in HVAC and water supply and drainage.

The raw material belt is produced with imported materials and advanced technology, with excellent quality and complete specifications, which can meet the requirements of different customers in different industries. The products have extremely superior insulation, strong chemical stability and good sealing performance, and are widely used in machinery, chemical industry, metallurgy, electric power, shipbuilding, aerospace, medicine, electronics and other industrial fields.

The raw tape needs to be wound in the direction of the thread, the reverse sealing performance is greatly reduced.

Do not wrap all the threads around the raw tape, as it will not only prevent the raw tape from entering the pipe, but also reduce the sealing performance. It is recommended to start winding from the second thread at the beginning of the thread and leave the first thread out; When winding the raw material belt, you need to use a little force to ensure that the raw material belt is not wound under the condition of being broken, and the raw material belt wrapped in this way is tight and firm enough to ensure the sealing.

As for how many times the raw meal belt is wound, here is a reminder to make the thickness of the second half of the winding raw meal belt larger, that is, the front is thin and the back is thick, so as to ensure that the thread is tightened and tightened, and the sealing performance is increased; After the raw material belt is wound, once the threaded pipe is tightened, do not withdraw the wire, otherwise it needs to be rewound and tightened.

1. Take the faucet as an example, wrap it along the outer edge of the faucet from the inside, remember to wind it counterclockwise along the thread of the faucet, and pay attention to the raw material belt not to completely wrap the thread when winding, because when installing the faucet pipe, it is easy to wrap into the faucet pipe.

2. When winding the raw material belt, let the raw material belt adhere to the thread of the faucet, and do not wrap it loosely with a little force, of course, some people like to press it while winding, this according to their own habits, remember that the raw material belt is tightly wrapped in the thread.

3. The winding raw material belt is generally more than 5 circles, and the winding circles of different plumbing parts are slightly different, and the number of winding circles can be selected according to the specific situation, like the faucet is generally about 10 circles, but some raw material belts are relatively thick and can be wound 8 times.

4. When the raw material belt is wound, you can press it by hand to see if the raw material belt is wrapped more tightly along the plumbing pipe fittings.

The method of winding raw material tape is as follows:

1. The raw material belt should be wound along the direction of the thread, and the direction should not be reversed.

2. When winding the raw material belt, start from the second tooth of the thread head, and leave the first tooth not entangled, mainly to avoid the raw material belt from entering the pipeline.

3. When winding, it is necessary to use a slight force, and there is a certain elongation rate in the case of keeping the raw material belt not being pulled off, so that the raw material belt can be tight and reliable, so as to ensure that there is no leakage.

4. The number of layers of winding is determined according to the tightness of the thread, and the thickness should be tapered when winding, that is, the front of the thread can be slightly thinner, and the further back it is, the thicker it is, so as to ensure that the thread is tighter and tighter, and has a sealing effect.

5. After the raw meal belt is wound, once it is tightened, it is not allowed to withdraw (twist back), otherwise it must be rewound.

Raw material belt is a commonly used auxiliary product in plumbing installation, which is used at the pipe fitting connection to enhance the tightness of the pipe connection. The chemical name of the raw material belt is PTFE, and ordinary white PTFE belts are commonly used in HVAC and water supply and drainage, and natural gas pipelines also have special PTFE belts, in fact, the main raw materials are PTFE, but some processes are different.

Wrap the raw material tape, it should be wound counterclockwise along the wire mouth, because this will be tighter and tighter when screwing.

Remove the foreign matter from the part to be connected to the raw tape, and pay attention to the winding direction. Take the angle valve as an example, the angle valve rotates clockwise to the right when it is screwed into the inner wire thread of the wall. Then the direction in which we wrap the leftover tape on the angle valve is to the left counterclockwise, so that when we tighten the angle valve, it will be tighter and tighter, and it will not loosen.

The tape should be stored in the warehouse to avoid sun and rain. It is forbidden to contact with acid and alkali oil organic solvents, and keep it clean and dry. 1m away from the discovery device, the room temperature is between -15 40.

Tape should be placed in rolls, not folded, and turned quarterly if stored for too long. When loading and unloading the conveyor belt, it is best to use a crane and a rigging with a beam to lift it smoothly to avoid damaging the belt edge. Do not load and unload arbitrarily, causing loose rolls and throwing sleeves.

The type and specification of the tape should be reasonably selected according to the needs of use and specific conditions.

The material of the raw tape

The raw tape material is a white opaque film-like PTFE product, which is a commonly used auxiliary product in plumbing installation. The chemical name is polytetrafluoroethylene, and the trade name is polytetrafluoroethylene-raw meal belt. Raw tape is the common name of PTFE-raw meal belt, which is mainly used at the interface connection of hot and cold water supply pipe fittings, to enhance the tightness of the pipeline connection, prevent the interface from leaking, and increase the leakage prevention effect of the interface.

Polytetrafluoroethylene, abbreviated as Teflon, is commonly referred to as a "non-stick coating" or "easy-to-clean material". This mausoleum material has the characteristics of anti-acid, anti-alkali and anti-stress Zheng various organic solvents, and is almost insoluble in all solvents. At the same time, PTFE has the characteristics of high temperature resistance, and its coefficient of friction is very low, so it can be used for lubrication, and it has also become an ideal coating for the inner layer of easy-to-clean water pipes.
