PVC and CPVC have various applications, therefore they space not frequently used in the same types of applications. CPVC goes through an extra chlorination process, which lets it resist high temperature much much more effectively than continual PVC. If PVC start deteriorating at 140F, CPVC stays strong up to 200F, which renders it perfect for water it is provided lines. PVC, on the other hand, is many often uncovered in drainpipe lines due to the fact that it’s cheap and doesn’t rust. However if it was necessary, would gluing PVC to CPVC it is in possible?

Are CPVC and PVC sizes Compatible?

The very first thing to consider is size. Are the sizing systems even compatible? All major brand PVC pipeline is made to NPS (Nominal pipe Size) standards, or “schedules.” Schedule 40 and also 80 space the most usual NPS schedules. The schedule determines just how thick the wall of the pipe will certainly be. The size name (given in inches) is simply a nominal size, therefore the measurements will no be specifically that size. A 1” schedule 40 pipe, for example, will have a 1.029” id (inside diameter) and a 1.315” OD (outside diameter). Sch. 80 PVC and sch. 80 CPVC will certainly fit together since they have actually the same ID and also OD. The exact same is true of schedule 40 PVC and CPVC, but that type of CPVC is seldom used.

One major difference between these two types of piping, once it involves sizing, is the reality that CPVC is make in two different sizing systems: NPS and also CTS. CTS (Copper tube Size) is, together the name suggests, the exact same size as copper piping. This is a source of confusion, as CTS CPVC and copper are both frequently used because that the exact same jobs. CTS pipes and also NPS tube are no compatible. Normally CTS CPVC is yellowish in color, if NPS CPVC is gray (sch. 80) or off-white (sch. 40). They room also significant on the outside, so telling different varieties of piping apart need to not be difficult.

Does CPVC come PVC glue Exist?

Just since CPVC and also PVC have the right to fit together, this does no necessarily mean they can actually be implemented into a working system.PVC cement (or glue) walk not work-related like continual glue. It breaks under the surface ar of the pipe it is applied to and chemically bonds pipes and also fittings together. Because that this reason, you cannot usage just any PVC cement to join these two materials together. CPVC, as we defined earlier, is a more powerful version the PVC pipe through a higher melting point and tougher chemical structure. This means old-fashioned PVC cement will certainly not be totally effective ~ above CPVC.

There is no one-of-a-kind “CPVC to PVC glue,” so chemically joining CPVC and also PVC needs solvent cement and primer that are solid enough to fully bond CPVC pipe. To attach PVC come a CPVC fitting (or evil versa) follow this steps:

Brush CPVC primer on the outside of the pipe and also inside of the fitting about 2 inch deep.Immediately apply a irradiate layer of CPVC cement to the area the is primed external the pipe and also inside the fitting.Slide and also twist the pieces together then organize them with each other firmly for 30 seconds.

Should PVC and CPVC it is in Glued Together?

Despite whether or no these two products can it is in cemented and also bonded to every other, the most crucial question is, “Why must you?” together we mentioned at the beginning of this post, PVC and CPVC, in spite of having three letters in common, have actually non-identical chemical structures which do them advantageous for different applications. PVC, v a max temperature that 140F is usually only provided for drainage. CPVC, which have the right to handle a balmy 200F, have the right to be used for warm water lines as a low-cost alternative to copper.

The bottom line is that if you have a mechanism that consists of both PVC and CPVC parts, girlfriend will have to ensure its demands are no better than lowest usual denominator of those components. In English: A device with both PVC and CPVC will should remain under 140F. This pipeline the CPVC underutilized. CPVC is more expensive than PVC, so over there is rarely a justifiable reason to affix the two. The can be done if necessary, yet it is essentially pointless. Make a system out of solely PVC would certainly serve the same purpose and also save money!
