Can PP material water pipe and PPR water pipe be connected?

OK. Is underfloor heating done with PPR? This one is less common anymore. Nowadays, it is usually made with PE series materials such as PE-RT. Because PP pipes are usually harder, PE pipes are more flexible and easier to construct.

As for the connection, the PE pipe is directly connected to the water separator, and the branch can be connected to the main pipeline by using aluminum-plastic composite pipe or PPR steady pipe (hot melt required).

If it's your case, it's more troublesome, and you can only use metal pipe fittings to link it.

Scheme 1: Purchase PP pipe fittings, connect them with PP pipe hot melt, and then convert them into copper pipe fittings with wire pairings, connect them with aluminum-plastic pipes, and connect aluminum-plastic pipes with water separators.

Scheme 2: Purchase PP pipe fittings, connect with PP pipe hot melt, and then convert them into PPR pipe fittings with wire, connect with PPR pipe, and finally connect with water separator.

The two are different materials, PP means polypropylene resin, PP-R English name is polypropylene copolymerized random, PP-R is the abbreviation of polypropylene random copolymer, and is also used to refer to the special conveying material for cold water pipes and hot water. PP-R pipes are also called three-type polypropylene pipes, although both have polypropylene, the two pipes are connected by hot melt, but the molecular structure is not the same and cannot be connected to each other. Even if it is connected, it cannot withstand much pressure and is prone to water leakage.

If you need an adapter for connection.

After the home decoration is completed, there are often some materials that are not used, throw away and feel a little wasteful, after all, it is also purchased with the decoration budget, we are human witty, good at thinking, often have some good thinking, make ideas works, today we want to ** is to use a pvc pipe to make dozens of good-looking furniture, maybe you will say useless, to show you another form of coffee table made in this way:

As long as you are careful, as long as you are not lazy, such a storage tool is very easy to complete, growing vegetables on the balcony is not only very practical, but also has the advantage of being very good-looking, transforming the PVC pipe into the shape shown below, sprinkling seeds in each tube, both vegetables to eat, and can be decorated, isn't it killing two birds with one stone?

It is made of PVC pipe connectors and can be used to store hair dryers and curling irons, which is very practical.

Maybe you feel that these are too complicated, how about this, it's very simple! Most of the children use this kind of weaving.

Decorate the skeleton with a chair cloth, and a cute and cute children's chair is immediately made!

Make a small groove in the bottom of the PVC water pipe to hang a goblet for a goblet.

It can be connected, but it cannot be directly hot-melted.

It should be connected by thread conversion! The connection effect is definitely different for different materials! It can't be welded directly!

PPR pipes and PE pipes can be connected with flanges.

When encountering the connection of PE pipe and PPR pipe, in order to save time, the installer often adopts the connection method of hot melt butt and directly heats the docking. In fact, this connection method is wrong, because the melting point of the two materials is different, the bonding performance is not good, and the connection strength is much lower than that of the same material.

The correct connection method for PE pipe and PPR pipe is to use flange for connection. The flange connection avoids the hot melt connection between two different materials, and the small diameter PE pipe and PPR pipe can also be connected with tooth fittings. Only these two connection methods can ensure the connection strength between the PE pipe and the PPR pipe, so as to ensure the quality of the project.

Precautions for the use of PPR tubes

1. The PPR pipe does not have too high hardness, so in the process of transportation, it is necessary to take necessary protective measures, otherwise there will be bumps, which is likely to cause cracks and cannot be used normally. When the pipeline construction is carried out in the later stage, it is necessary to mark the location of the pipeline in the design drawings, so as to prevent the secondary construction from causing damage to it.

2. If you are in winter construction, you also need to pay attention to the preservation and use of PPR pipes, after all, in the weather below 5 degrees, PPR pipes are brittle, if you need to cut, the props used need to be very sharp, and the process should be kept as slow as possible. In addition, after the construction of the pipeline, do not apply pressure.

3. PPR pipe can not be exposed to ultraviolet rays for a long time, otherwise it is very easy to age, so it is mostly used for indoor decoration, if it is used for outdoor construction, it needs to be installed with an additional layer of protective layer. At the same time, during the construction of PPR pipelines, it is necessary to prevent them from deforming due to expansion.

PPR tubes. Steps to connect with PVC pipe:

1. First of all, the PPR pipe is combined with the PVC pipe.

Clean the burrs and sanitary cloth at the joint part;

2. Use a tape measure to measure the size of the shell;

3. Mark the size of the connection between the PPR pipe and the PVC pipe joint;

4. According to the size of the mark, the welding hole of the casing is heated and stretched by electrofusion, and the outer diameter of the joint of the PPR pipe and PVC pipe is heated and reduced;

5. Insert the connecting end of the PPR pipe and the PVC pipe into the casing and fix it for more than 10s.

The first is connected with a flange.

The second is spliced by the order, one end is PP and the other end is PVC.

If it's convenient, it's the second option.

PPR and PVC can't be hot melted at all Professional PVC adhesive is bonded between PVC.

The heat honor between PPR is very good, so the above two methods are the safest, and there will be no problemsPPR pipe and PVC pipe can not be bonded with hot melt or glue due to different materials.

PPR and PVC pipes can be connected using threaded, union or flanged connections.

Threaded connection: hot melt one end of the PPR pipe with a PPR inner wire directly (or the outer wire directly), and then glue one end of the PVC pipe to bond an outer wire directly (or the inner wire directly), and then screw the inner and outer wires together directly;

Union connection: in a PPR double hot melt union, one end is hot melt with PPR pipe, and the other end is replaced with a PVC union and bonded to PVC pipe, and the union can be tightened after the union is screwed;

Flange connection: hot melt the PPR flange with the PPR pipe, and the PVC flange is bonded with the PVC pipe, and then tighten the 2 pieces of flange with screws.

Either way, care must be taken not to forget to put a gasket or wrap a seal tape.

PVC drain pipes can be joined with adhesives. First of all, use a fine-toothed saw and a cutter to cut the PVC drainage pipe according to the size. Use a blow hammer to remove the fracture burrs and burrs, and chamfer.

Wipe the surface of the socket with a dry cloth with dust, water, and oil. Apply the adhesive evenly to the socket area. Quickly insert the socket into the socket and turn into a quarter turn, holding for at least 10 minutes for the adhesive to cure.

Use a cloth to wipe off any excess adhesive on the outside and allow water to run through it 2 hours after it is attached.

PPR water pipes and PVC water pipes are generally not directly connected, and if you really need to connect, you may need to use union or stainless steel corrugated pipe to connect.

Hello! Glad for your question. Can plastic pipes and PPR pipes be connected together?

Yes 1. Weld with a fuser, which is also the most basic method. Because they are all the same kind of plastic, the fuser can control the temperature of the leakage stool, the outer wall of the pipe and the inner wall of the pipe fittings are melted at the same time, and the temperature is also the same. 2. If it is an emergency treatment, you can use the quick connection to change the high joint, which is convenient and fast without electricity, and it can be used temporarily.

Can PPR pipe be connected with water in hot melt? :Pro-not, the PPR pipe hot melt can not be connected with water, it is strictly forbidden to have water in the high-end home improvement PPR pipe cleanliness pipe engineer must first clearly point out: PPR pipe hot melt welding is strictly forbidden to weld in the presence of water, because the PPR pipe welding temperature must be controlled between 260 -280, if there is water, stick to the welding die that has been heated, the water at high temperature, instantaneous vaporization, vaporization heat absorption will reduce the temperature of the fuser, the heating temperature of the PPR pipe is not enough will lead to the cold seam delamination at the weld, Welds with cold seam delamination are bound to leak, which is why PPR pipe welding must be dry and not water-free.

Summary. Hello, 1. We can use the adapter to connect the PVC pipe and the PPR pipe together, and we can connect one end of the adapter and the PPR pipe together through the hot melt machine. Apply PVC glue to the other end of the adapter and bond it to the PVC pipe.

2. You can use flanges to fix PVC pipes and PPR pipes together. We prepare a PPR flange and PVC flange, fix the PPR flange and PPR through hot melting, and bond the PVC flange and PVC pipe with glue. Put a gasket between the two flanges for sealing, and fix the PPR and PVC flanges together with screws.

Hello, 1. We can use the adapter to connect the PVC pipe and the PPR pipe together, and we can connect one end of the adapter and the PPR pipe together through the hot melt machine. The other end of the adapter is coated with PVC glue to bond and fix the state hyok cherry and the PVC pipe together. 2. You can use flanges to fix PVC pipes and PPR pipes together.

We prepare a PPR flange and PVC flange, fix the PPR flange and PPR through hot melting, and bond the PVC flange and PVC pipe with glue. Put a gasket between the two flanges for sealing, and fix the CPR and PVC flanges together with screws.

What should be paid attention to in the connection of PPR pipes1, before we connect the two leaky PPR pipes together, we must first clean the connection ports. If there are problems such as dirt or burrs in the connection port, it may cause the pipe to be connected tightly when it is hot-melted. Before construction, you can use special scissors for water pipes to reduce part of the PPR pipe connection port, and wipe the connection of the Wudu pipe with a rag cavity search.

2. The specifications of PPR pipes are diverse, and the wall thickness of the pipes is different, resulting in different heating times. When we connect the PPR pipe, we must first understand the heating time of the pipe, for example, the heating time of DN20 pipe is 5 seconds, and the heating time of DN25 pipe is 7 seconds. If the heating time is too long or too short, it will affect the connection effect.

If the aperture of the pipe is relatively large, then the flange adapter can be used to connect the pipe together with the empty space. If the aperture of the pipe is relatively small, it should be connected through dental fittings. Note that PE and PPR pipe connection cannot be connected by hot melt method, which will lead to the pipe strength not reaching the standard.
