Difference between PVC pipe and PPR pipe How to connect PVC pipe and PPR pipe

September 26, 2021

PVC pipe and ppr pipe are the most common home improvement accessories in our home decoration. It is widely used in decoration and has played an important role. There is a certain difference between PVC pipe and ppr pipe . Today we have to make it for everyone. The difference between the PVC pipe and the PPR pipe and how to connect the PVC pipe and the PPR pipe are shared.

The difference between PVC pipe and PPR pipe

1. PPR pipe is mainly made of polypropylene, so PPR pipe is also called three-type polypropylene pipe, and PVC is made of polyvinyl chloride material. Different, resulting in different performance and characteristics, but also because of the different raw materials, PPR pipe installation is mostly hot melt, and PVC pipe is mostly adhesive, which is one of the differences between PVC pipe and ppr pipe .

2. The wall thickness of the PPR pipe is divided into a quarter pipe, a six pipe, etc., the wall thickness of the quarter pipe is 2.3 mm, and the wall thickness of the six pipe is 3.5 mm. The PVC pipe is caliber 6mm wall thickness 2.0mm, nominal diameter 8-10mm wall thickness 2.5mm and so on.

3. Because of the different wall thickness of the pipe, the price will naturally be different, and the consumption level will be different in different regions. In Guangzhou, the general PPR pipe is between 10 yuan and 16 yuan per meter, and the PVC pipe 50*2 is 6 Between yuan per meter, between 10 yuan per meter of 75*2.3, between 18 yuan per meter of 110*3.2, and between 36 yuan per meter of 160*4.

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

5. The difference between PVC pipes and ppr pipes ? Their scope of application and characteristics are different. If it is only used for waterway reconstruction, then from the quality point of view, it is certainly more appropriate for PPR management, but one thing we should pay attention to is that A lot of PPR pipes will be marked: can not be installed, here can not be installed can not be installed in the outdoor exposure to sunlight, if the PPR pipe installed outdoors, it is generally necessary to change the pipe for two years to avoid breeding bacteria, affect the service life .

How to connect PVC pipe and PPR pipe

1. PPR pipe and PVC pipe cannot use hot-melt or glue bonding because of different materials. PPR pipe and PVC pipe can be connected by screw connection, live connection or flange connection.

2. The threaded connection is to heat the end of the PPR pipe, and then one end of the PVC pipe is glued to a pipe, and then the inner pipe and the outer pipe are screwed together.

3. The live connection method is that one end of the pipe is hot-melted with the PPR pipe, and the other end is replaced with a PVC joint and bonded with the PVC pipe, and the live connection can be tightened.

4. Flange connection is to heat the PPR flange and PPR pipe, and the PVC flange and PVC pipe are bonded to each other, and then the two flanges are fixed by screws.

5. Regardless of any of the above methods, care must be taken not to forget to place a gasket or seal the tape.
