How to connect the joints of plastic water pipes

There are three main ways to connect plastic "water supply" pipes:

1, bonded with special glue, suitable for PVC water supply pipeline.

2. Hot melt connection is used for PP-R pipe and RPAP5 pipe.

3. Electric fusion connection is adopted, which is suitable for indoor and outdoor large-diameter PE water supply pipes.

How to connect plastic water pipes?

If there is no thread, then butt weld with a hot melt machine and paste it after heating.

How to connect plastic water pipes

If it is PPR (white) or pe (black) pipe, add the pipe with a hot-melt machine for ancient fusion connection.

If it's just an ordinary plastic pipe, connect it with a raw material belt wrapped in iron sheet. There is a pinch joint, which is easy to collapse when the water pressure is high, and it is not recommended.

If it is PVC, connect it to the pipe with water glue.

How big are the above pipes? How old are these pipes? When it is necessary to reduce the diameter, use the reducing joint.

If it is a whole house water heating design, it needs to put forward new problems. When asking questions, be clear about the size of the room and the installation location of various water heating facilities. It is better to have a picture.

How to connect the plastic water pipe to the elbow?

It is heat-sealed with a plastic elbow with a fuser.

The connection method with the metal elbow is: insert the plastic pipe into the threaded joint through heat sealing, and then connect the metal elbow with the nut sleeve metal pipe connection method.

Heating connection method of household tap water plastic pipe

Domestic water pipes are generally connected with plastic water pipes by hot melt heating. Others depend on the material, and different materials have different connection methods.

The simplest connection method of plastic water pipes

Use connectors of the same model and thread, and seal them with raw material tape.

Of course, it can also be sealed with glue, which is more suitable for sewage pipes. Domestic water is not good and polluted.

How to connect water pipes

You can use dry drama to cut water pipes, or you can borrow special scissors for cutting water pipes from the store.

There is an indicator light on the fuser, which will light up when the power is connected. The light is out and can be used to connect the water pipe. There are two heads on the machine, one is a water pipe and the other is a joint. When the temperature is reached, put the pipe fittings on.

You can go to the place where you borrow the fuser and ask the store how to install it, but you'd better find a professional electrician, because some bad water pipes will be blocked if they are installed for too long.

How to connect plastic water pipes and iron pipes?

There are many ways to connect cast iron pipes with PVC drainage pipes, such as socket connection, clamp connection, adhesive connection and thermal connection.

The so-called adhesive bonding is to bond and fix the cast iron pipe and PVC drainage pipe with suitable adhesive, and the thermal bonding adopts the method of external plastic thermosetting. Of course, there is something simpler, that is, bake the torch PVC drainage pipe soft, and pay attention not to scorch it. Then use the beer bottle at home as a flaring device to expand the PVC pipe, and then connect the cast iron with the PVC pipe. Pay attention to tighten when connecting. If there are many interfaces installed, use the following methods: find a container, put it in paraffin and heat it into water. At this time, the paraffin temperature is already very high. Put the PVC pipe head into the heated paraffin. Usually PVC drainage pipes will soften when heated. Just wait for the joint to become soft before taking it out, and make sure it doesn't leak.

PVC drainage pipes are generally used in the field of transportation pipelines, and are generally mainly used for sewage drainage pipes. The pressure that PVC drainage pipes can withstand is generally directly related to the wall thickness, quality and filler of the drainage pipes. PVC pipes and drains are usually white and can be customized for users. PVC pipes and drainage pipes are resistant to all kinds of corrosion, such as acid, alkali and salt. Of course, PVC drainage pipes are also common pipes in our lives.

Can the plastic pipe of tap water at home be connected with the old iron pipe of tap water upstairs?

Plastic water pipes can be connected with old water iron pipes. Plastic water pipes and iron pipes need external threads at the connecting ends. Buy a hose nipple with a double-headed nut (the same as the external thread), and screw the nut on both ends of the plastic water pipe and the iron pipe respectively to complete the connection. Convenient and easy to use.

How to connect plastic pipes with plastic pipes? Don't quickly connect the buried tap water.

Heat the plastic pipe joint to be butted with a hot melt gun to soften it, quickly insert another plastic pipe and cool it.
