What is the difference between PVC and CPVC?
To explain, you need to understand the difference between PVC and CPVC. PVC stands for polyvinyl chloride, while CPVC stands for chlorinated polyvinyl chloride. CPVC cement, on the other hand, has no problem holding CPVC together, and since it has a more durable structure, it can hold PVC pipe together as well. Click to see full answer.
What is a cpv cement?
The Oatey 8 oz. CPVC Cement is formulated to bond CPVC pipe and fittings in water-distribution systems. The solvent cement softens the surface of pipe and fittings to create a strong bond.
Is PVC the same size as CPVC?
Furthermore, is PVC and CPVC the same size? PVC and CPVC are the same size when referring "nominal" size. Meaning, if measure the OD (outside diameter) of 1/2" PVC or 1/2" CPVC, they are the same at .
Can you use PVC glue on CPVC?
Keeping this in view, is it OK to use PVC glue on CPVC? A: Yes. CPVC solvent cement technically will work on PVC piping. However, we recommend that the correct Weld-On primer and PVC solvent cement for the particular application should be used.
Do you need to prime PVC before cementing?
There are a few specialty PVC and CPVC cements which do not require the pipe / fittings to be primed before the cementing process, but you still must check with your local municipality to see if they require priming the pipe and fittings first. Remember to never use primer on or with ABS products.
Why should you use PVC and CPVC?
PVC, with a max temperature of 140F is usually only used for drainage. CPVC, which can handle a balmy 200F, can be used for hot water lines as a low-cost alternative to copper.
How to bond PVC to PVC?
There is no special “CPVC to PVC glue,” so chemically joining CPVC and PVC requires solvent cement and primer that are strong enough to fully bond CPVC pipe. To connect PVC to a CPVC fitting (or vice versa) follow these steps: 1 Brush CPVC primer on the outside of the pipe and inside of the fitting about 2 inches deep. 2 Immediately apply a light layer of CPVC cement to the area that is primed outside the pipe and inside the fitting. 3 Slide and twist the pieces together then hold them together firmly for 30 seconds.
What is the difference between schedule 40 and CPVC?
One major difference between these two types of piping, when it comes to sizing, is the fact that CPVC is made in two different sizing systems: NPS and CTS. CTS (Copper Tube Size) is, as the name suggests, the same size as copper piping.
How strong is CPVC?
While PVC starts deteriorating at 140F, CPVC stays strong up to 200F, which makes it perfect for water supply lines.
What temperature is PVC?
PVC, with a max temperature of 140F is usually only used for drainage. CPVC, which can handle a balmy 200F, can be used for hot water lines as a low-cost alternative to copper.
Is CPVC more expensive than PVC?
This leaves the CPVC underutilized. CPVC is more expensive than PVC, so there is rarely a justifiable reason to connect the two. It can be done if necessary, but it is essentially pointless.
Can you glue PVC to CPVC?
There is no special “CPVC to PVC glue,” so chemically joining CPVC and PVC requires solvent cement and primer that are strong enough to fully bond CPVC pipe. To connect PVC to a CPVC fitting (or vice versa) follow these steps:
What is the difference between PVC and CPVC?
The main difference between CPVC and PVC is the range of temperatures each is capable of withstanding. CPVC can handle temperatures up to 200° Fahrenheit, while PVC peaks at 140° Fahrenheit. Above those temperatures, both CPVC and PVC will begin to soften, increasing the risk of joints and pipes failing, and therefore, ...
Why are primers different for PVC and CPVC?
The primers, solvent cements, and bonding agents are different for PVC and CPVC due to the differences in the material's chemical composition. For example, CPVC solvent cements must meet ASTM F493 specifications, and PVC solvent cements must meet ASTM D2564 specifications. Because of this, CPVC and PVC pipes and fittings, ...
What is PVC pipe?
Commonly used to create plumbing pipes and fittings, polyvinyl chloride is a man-made plastic with added stabilizers that prevent oxidation and degradation. As seen in the image below, PVC’s chemical composition is made of two carbon atoms linked together with a perimeter of three hydrogen atoms and one chlorine atom, all attached by single bonds. This individual molecule unit (a monomer) is then further linked together with other molecules of the exact same structure to form chains (a polymer) that are extruded as PVC to form PVC products like pipe.
What temperature should PVC pipes be used for?
Since PVC has a maximum temperature threshold of 140° Fahrenheit, its use isn’t recommended in applications where the temperature of the fluids it will carry or its ambient environment will regularly approach, remain constant at or go above that peak temperature. CPVC would be recommended in these situations since its peak temperature threshold is 200° Fahrenheit. You may be surprised to learn that household water temperatures are not supposed to go above 140° Fahrenheit:
How long is PVC pipe?
PVC is available in 10 ft and 20 ft lengths. CPVC is available in 10 ft and 20 ft lengths. Certain diameters of PVC pipe and furniture PVC pipe are now available in 5 ft sections.
Why does PVC fail?
Reasons PVC may fail include: poorly glued joints or tree roots displacing underground lines or burrowing their way into the pipe itself. For more on what is PVC, the characteristics and properties of the plastic, read our resource article What is PVC | What is uPVC.
What is the temperature of PVC?
PVC has a peak temperature threshold of 140° Fahrenheit. For applications requiring temperatures above that, CPVC (chlorinated polyvinyl chloride) is recommended. CPVC offers some benefits over PVC, but at a slightly higher price point.
Can you use primer on plastic tubing?
The two types of plastic are very different and so are the cleaners, primers and cements. Unless you use All Purpose you must use the proper cleaner, primer and cement for the tubing being used. All manufacturers will say that and IMO it's not to cover their butts although it could be but I wouldn't bet my house and its contents on it simply to save redoing some plumbing I've just done.
Can you tell if a pipe joint will hold?
Bottom line is that NO ONE can tell you that the joints will or will not hold. Even if you followed all procedures properly, used the right cleaners and glue and the same pipe types, there is ALWAYS the possibility of a leak. It is now up to you to decide if you want to take the chance or not. Upvote.
Does Cpvc break before joint?
The cpvc will break before the joint breaks.
What is the difference between PVC and CPVC?
To explain, you need to understand the difference between PVC and CPVC. PVC stands for polyvinyl chloride, while CPVC stands for chlorinated polyvinyl chloride. CPVC, as its name suggests, undergoes an extra chlorination process before being put on the market. The chlorination makes the pipe stronger, harder and smoother, with fewer pores.
What temperature can PVC pipe be?
As a comparison, PVC pipe can only handle temperatures of up to 140 degrees F. Because of CPVC's higher strength, and the usually higher temperature of water flowing through it, the cement that is made for it (CPVC cement) must be a stronger, more durable adhesive.
Can PVC cement be used to hold CPVC pipes together?
PVC cement is nothing to scoff at however, and holds PVC pipes together firmly, but it can't be used to hold CPVC pipes together, as the cement would melt or erode with the constant flow of hot water. CPVC cement, on the other hand, has no problem holding CPVC together, and since it has a more durable structure, ...
Is CPVC better than PVC?
While both PVC and CPVC work just fine for cold -water plumbing, CPVC works better with hot-water plumbing, as PVC pipes will erode and fail over time if hot water is continuously forced through them. CPVC, on the other hand, because of its higher durability, has a higher temperature tolerance, and can hold water of temperatures up ...
Can you use PVC cement to bond PVC pipes?
CPVC cement, on the other hand, has no problem holding CPVC together, and since it has a more durable structure, it can hold PVC pipe together as well. So, if all you have to bond two PVC pipes and fittings together is CPVC cement, it will work, but PVC cement cannot be used to bond CPVC pipes and fittings.
Material Composition
Temperature Rating
- Perhaps the biggest determinant of which pipe to use in as far as PVC and CPVC are concerned is their temperature ratings. And without a doubt this is the main difference between PVC and CPVC. As I have already mentioned, PVC pipes and fittings can withstand temperature of up to 140 degrees Fahrenheit. On the other hand, their improved cousins (CPVC) can handle temperatures …
Lifespan
- Both PVC and CPVC can last for a very long time. On average, PVC pipes will last for about 50 years although they can last even longer depending on where they are installed and how well they are installed. Pipes installed in areas where there are tree roots are likely to last for fewer years than pipes installed far from tree roots. Less physical activities like driving on top of buried pipe…
Solvent Cements
- The main reason it is not recommended to glue PVC and CPVC pipes together is because the two types of pipes need different types of solvent cements to be joined together. As I mentioned earlier, PVC solvent cements must meet ASTM D2564 specifications while CPVC solvent cements must meet ASTM F494 specifications. Remember, a connection is only as strong as its weakest …
Sizing
- One of the main questions most people ask concerning PVC and CPVC is “Is a PVC and CPVC of the same size”? This may sound like a simple question but it isn’t. Well, the simple answer is YES. PVC pipes and CPVC pipes are of the same sizes. But there is more than just that. The confusion arises because PVC pipes only use nominal pipe sizes while CPVC...
Flexibility
- If flexibility is important to you like when you need to install a pipe around a curve, CPVC pipe is the clear winner here. It is way more flexible than PVC pipe. I should mention that due to its flexibility a CPVC pipe will need to be supported at intervals of 3 feet. If that is not done the pipe will start to belly and put strain on the joints. If I can tie ductility to this point, PVC pipes are less …
Identification/Color
- Most people get confused when it comes to colors and plastic pipes. Most of the PVC pipes you will see around in residential places will be white. As a matter of fact, most people refer to PVC pipes as white plumbing pipes in a bid to distinguish them from the grayelectrical conduit PVC pipes. What you may not however know is that only schedule 40 PVC pipes are white. Anyway, t…
Cost
- PVC pipes and fittings are less expensive compared to CPVC pipes and fittings. And that makes perfect sense. The extra chlorination process in the conversion of PVC into PVC increases the cost of production of CPVC pipes and fittings. Both of these pipes are however way cheaper compared to steel and copper.
Application
- Both PVC and CPVC can be used in many different areas including but not limited to: 1. Sewer lines 2. Sprinkler systems 3. Irrigation 4. Chemical applications 5. Manufacturing 6. Water distribution 7. HVAC 8. Electrical installations It becomes critical when the fluid being carried by the pipe is hot. Without sounding repetitive, CPVC is better at handling hot fluids compared to P…
