The difference between PVC and PPR in plastic water pipes and their properties

Supplementary 1PPR is the water supply pipe, PVC has drainage, and there is also water supply. PPR connection is: hot melt, flange, PVC drainage connection:

Adhesive PVC water supply connection method: adhesive, flange connection, flange gate valve, rubber ring connection The biggest difference is that PPR uses electricity, PVC does not use electricity, in some suburbs and wild places, it is not so troublesome to use PPR, you need to pull electricity, and PVC is very simple, with some glue or rubber ring is OK. Depending on the design, geographical needs.

2PPR is mainly used for interior decoration, PVC water supply is mainly used for urban water conservancy construction and transformation, agricultural irrigation, etc.

There is also a difference in waywardness, the pipes of PPR can be bent, and the pipes of PVC are brittle and cannot be bent! There are also requirements in terms of pressure, PPR pipes are basically used as water supply pipes for water supply, and there are requirements for water pressure, while PVC pipes are used for sewer pipes, and there are no requirements for water pressure!

1. Different: PVC is relatively low, which is also one of its major advantages, while PPR is more expensive. 2. There is a difference in color and luster:

The PPR pipe is milky yellow, if the surface of the poor quality water pipe is dull, the PVC pipe is milky white and the surface is shiny. 3. Different wall thicknesses: PPR pipe wall is thicker, PVC pipe wall is thinner.

How to choose a good PPR tube.

1. "Touch": First of all, touch the pipe with your hands to see whether the surface texture is delicate and whether there are burrs on the surface. There are several colors such as white, gray and green in the PPR tubes on the market, so don't think that white is the best when choosing, and you can't judge the quality from the color alone.

Therefore, when purchasing, it is best to touch the surface of the pipe, if the surface is rough, it may be involved in other materials, so be cautious about purchasing.

2. "Smell": Secondly, you can also smell the smell, the PPR pipe is made of polypropylene, if it is the first to smell, there is no smell, so you can smell the smell of the pipe if it is bad.

3. The hardness of the "pinching" :p PR pipe is very high, if it is deformed with a casual pinch, it means that the quality of the PPR pipe is very poor, and do not buy it in this case.

4. "Smashing": Usually the PPR pipe has good elasticity and is not easy to smash, so when choosing, you can gently smash it on the ground, if it is broken, the quality is not good. In addition, it depends on its hardness, if the hardness is not good, it will break after not being used for a long time.

5. "Burning": Finally, you can also ignite a pipe, if there will be black smoke and unpleasant smell when burning, it means that the quality of the pipe is unreliable. The material will not have black smoke and no smell, and the melted liquid is very clean.

Summary: The above is about the difference between PPR water pipe and PVC water pipe, I hope it will be helpful to you! In short, the difference between these two types of water pipes is quite big, and the use occasions are different, it is recommended that you can choose water pipes according to the actual situation.

Qinqin is happy to answer for you the difference between :p pr and pvc water pipes, answer: Qinqin The main differences between PPR pipes and PVC pipes:

1. Different colors: PPR pipe material has toughness, the color of the first grade is bright, and it is accompanied by light milky yellow, and the color of poor quality is mixed. PVC pipe is milky white, the material is hard and brittle, the section is dull, but the surface is shiny.

2. Different wall thickness: PPR pipe and PVC pipe have the same diameter, which is distinguished by the thickness of the pipe wall, the thickness of PPR pipe, and the thin wall of PVC pipe. All PP-R pipes and PVC pipes have words on them, and the toughness of PPR pipes is good, under the same diameter, usually the PPR pipe wall should be thick.

1. Different materials: the main difference between PE water pipe and PPR water pipe is the material, the material of PE pipe is polyethylene, the material is medium density polyethylene, the elastic modulus is only about 550MPa, the flexibility is good, but the stiffness is insufficient, and the material of PPR pipe is random copolymer polypropylene, the elastic modulus of PPR water pipe is 850MPa, the stiffness is good, but the flexibility is insufficient. Plastic PVC is a polyvinyl chloride resin material.

2. Different uses: Another difference between PE pipes and PPR pipes is the use, PE water pipes are often used for municipal water supply and drainage pipelines, while PPR water pipes are often used for building water supply and home decoration water supply pipelines. PVC pipes are used for water supply and drainage, irrigation, gas supply, exhaust pipes, wire conduits, rainwater pipes, industrial anti-corrosion pipes, etc. for residential life, industrial mining, and agriculture.

3. Different installation: PE water pipe and PPR water pipe installation and welding are also different, PPR water pipe installation and welding temperature is 260, PE water pipe installation and welding temperature is 230. The installation and welding temperature of PVC pipe is 200 230.

PVC installation precautions.

1. When installing, the size should be measured according to the requirements of the drawings, the pipe should be broken, and the fracture should be ensured.

2. It cannot be fully inserted before the connection of PVC pipes, and the socket needs to be test-inserted. When bonding, if there is oil, dust, and even moisture inside, it must be removed.

3. Inspection openings should be set at the bottom and top of the drainage pipe, and the center of the inspection port should be one meter from the ground.

4. During the installation, the pipe should be placed gently to avoid damage caused by the installation process and ensure that the pipe can be kept complete and clean. After installation, a pressure test should also be carried out to confirm that there is no water leakage at each interface, otherwise it needs to be replaced and reinstalled immediately.

1. PPR pipe is mainly made of copolypropylene, so PPR pipe is also known as type three polypropylene pipe, and PVC is made of polyvinyl chloride material, the main raw materials of the two kinds of pipes are different, resulting in different performance and characteristics, and it is precisely because of the different raw materials of hunger-resistant wheels, PPR pipes are mostly hot melt when installed, and PVC pipes are mostly glued, which is one of the differences between PVC pipes and PPR pipes.

2. The wall thickness of the PPR pipe is divided into four pipes, six pipes, etc., four pipes of wall thickness, and 6 pipes of wall thickness. The PVC pipe has a diameter of 6mm wall thickness, a nominal diameter of 8-10mm wall thickness, etc.

3. Due to the different wall thickness of the pipe, there will naturally be differences, and the consumption level in different regions is also different, in Guangzhou, the general PPR pipe is between 10 yuan and 16 yuan per meter, PVC pipe 50 * 2 between 6 yuan per meter, 75 * between 10 yuan per meter, 110 * between 18 yuan per meter, 160 * 4 between 36 yuan per meter.

4. The use is also different, PPR pipe is used as a water pipe pipe, which is divided into cold water pipe and hot water pipe. The PVC pipe Changxin is suitable for wire through the wall and used as a sewage pipe.

5. Their scope of application and characteristics are different, if they are only used for waterway transformation, then from the quality point of view, it must be that the PPR pipe will be more suitable, but there is one thing that we should pay attention to, there are many PPR pipes will be marked: not open-mounted, here the non-open-mount means that it cannot be installed outdoors under the sun, if the PPR pipe is installed outdoors, it is generally necessary to change the pipeline once every two years to avoid breeding bacteria and affecting the service life.

The above is the difference between PVC pipe and PPR pipe that I introduced to you, I believe you have a certain understanding of this, and I hope to help everyone.
