There are several types of PVC pipe that have their own characteristics.
Some pipes work well with water, some work well with flexibility. So you have to choose wisely before you purchase any pipe.
Do you want to know what types of PVC pipe there are?
There are four types of PVC pipes. PVC-U, C-PVC, PVC-O, PVC-Hi. Each pipe works well in different categories. Some pipes can handle extreme pressure of water while some don’t. You’ll find some working well in undergrounds while some don’t.
We have explained the types here in brief. If you have a minute, take a look at our detailed discussion.
Let’s dive into the details!
What Are The Types Of PVC Pipes? – Explained
There are 4 types of PVC pipe. PVC-U, C-PVC, PVC-O, PVC-Hi. Each type of PVC works in a different category. These pipes have their own advantages and features. There are also different kinds of pvc connections. However, we’ll only focus on their types.
Let’s see the features of the types of PVC pipes.
PVC-U pipe is known as unplasticized PVC pipe. That means this type of pipe is made without any plasticizer. It’s lightweight, affordable, and easy to fix or replace. PVC-U is used as fittings, transportations, sewage, industrial drainage, etc.
PVC-U is perfect for transporting water. It has a very good chemical resistance, UV exposure resistance which makes it more durable.
PVC-U is famous for its cost. It’s cheaper than any other pipe. Also, PVC-U pipes are the most eco-friendly pipe because it’s 100% recyclable. These pipes are also used for doors, windows, etc.
There are also some disadvantages of PVC-U pipes. As it has no plasticizer, it has poor heat resistance. The pipes can melt or crack at a boiling temperature.
That’s why you can’t use it for water heater pipes in the house. PVC-U can’t resist more than 60 degrees celsius. It starts to crack at this temperature.
The drain system made of PVC-U makes noise. The reason for this water running noise is lubrication in the inner side of the pipe. When water flows from there it resists the lubricant which results in noise.
C-PVC stands for chlorinated PVC. This pipe contains more chlorine than any other PVC pipe and was invented in the 60s. But day by day, the manufacturing process changed.
C-PVC pipes contain more chemicals. For example- pigments, stabilizers, lubricants, etc.
C-PVC is built to transport drinking water. These are also used as fittings, carrying other chemical liquids. C-PVC pipes have a great advantage. You can transport water at different temperatures through the pipes. That’s why C-PVC pipes are used in sewers or residential areas.
The high amount of chlorine also ensures germs are eliminated. C-PVC pipes are also more durable than UPVC pipes. C-PVC pipes are more flexible compared to UPVC pipes. It’s also 100% recyclable. So these features make the C-PVC pipes more usable.
There are some disadvantages as well. The pipe cracks in freezing temperatures. It has less UV protection than PVC-C. Direct sunlight exposes UV rays, which degrades the pipe.
Another problem is that the C-PVC melts at a very high temperature. It starts to melt, reaching 100-120 degrees celsius.
PVC-O is molecularly oriented PVC. This PVC pipe is another version of PVC-U. The difference is PVC-O has more layers in the structure. It’s heavier than PVC-U.
This type of pipe is also unplasticized. They are used at strong pressure water supplies, fittings, sewer, or irrigation pipes.
The biggest advantage of this type is it can handle pressure on unstable ground. It has higher resistance capability, water quality preservation, and low cost. You can also fix the leak joints in this pipe easily.
PVC-O pipe is more durable compared to PVC-U or PVC-C pipes. It has a perfect balance of strength and flexibility.
The disadvantages of PVC-O are it’s less flexible compared to other PVC pipes. This pipe melts at a boiling temperature. It can take up to 130-150 degrees celsius.
PVC-Hi is the newest creation of PVC pipes. This pipe contains more chemicals such as alkali. PVC-Hi is used in chemical industries.
PVC-Hi has excellent flexibility and power and it’s very durable. It has a smooth inner wall and lowers fluid resistance.
The most amazing feature of the pipe is that it can bear up to 8 scale earthquakes. The flow rate of water is also higher than metal pipes. Also, PVC-Hi pipes don’t affect the water. This pipe can bear extreme high and low temperatures.
Until now, PVC-Hi has had no issues. The only disadvantage is that it’s still in an experimental process. However, the experiment shows great results. So, you can use this pipe for your needs!
If you’re looking for the best PVC-Hi pipes, we have some suggestions for you:
You now have your PVC-Hi pipe, apply it!
That’s it! We have discussed every type of PVC pipe available.
Question: What is the best PVC pipe for water supply lines?
Answer: C-PVC pipes are ideal for water supply lines. It contains extra chlorine that kills the germs of the water. It’s also very durable when it comes to hot temperature waters. Also, C-PVC pipes water is safe for drinking.
Question: Are copper pipes better than PVC pipes?
Answer: Yes, copper pipes are better than PVC pipes. They can take extreme water pressure and don’t crack. Copper pipes also don’t make any noise while running water. Copper pipes are way more expensive than PVC pipes.
Question: How long does PVC pipes last?
Answer: Without any issues, PVC pipes last more than 100 years. But extreme temperature and extreme water flow can crack the pipe at any time. So be careful about the temperatures.
We can now end our discussion here. Now you know about the types of PVC pipes.
Before you purchase any type of pipe, you have to study it. We hope we have helped you with this article.
Till then, choose your pipes properly!
