Can you put PVC pipe together?
Depending on how strong you want the joints , you could just push them together and leave it unglued. I've done this to create poster tubes out of 3" PVC which went through airport baggage handling just fine. PVC fittings are tapered on the inside, so the further in the pipe goes the stronger it will naturally hold.
What cements do you need to apply primer?

How to weld a CPVC pipe?
Take a CPVC male adapter and solvent weld it to a CPVC pipe with primer. Take a CPVC elbow and solvent weld it to the other side of the CPVC pipe without primer. Repeat the same process on the other side of the elbow to create a pipe assembly containing one elbow, two short pieces of pipes and two male adapters. This pipe assembly contains a total of four solvent welded joints: two with primer application, two without. Refer to Figure 3 for a diagram.
Why are primed joints weaker than unprimed joints?
The final reason why the primed joints could be weaker than the unprimed joints could be that because the cement contains most of the same ingredients as the primer does , the primer may not have added any real benefit to the joint strength. The primer may have actually made the joint weaker.
What is primer used for in welding?
In addition to the cement, a primer may also be used during the solvent welding process to presoften the material to fuse and create maximum joint strength (Oatey, 2014). The primer is made of around 20%-40% acetone (Oatey, 2012). According to Hong and Wu (2000), the acetone used in their tests lowered the Tg of epoxy resins during their curing by decreasing the degree of cross-linking. The lowered Tg that the acetone in primer allows for the diffusion of the polymer chains at a lower temperature than would normally be required. Therefore, in solvent welding, the heat normally required by other types of welding is not required ("Thermal properties of polymers", n.d.).
What is the strongest cement?
The strongest cement was the Medium Gray PVC cement. The weakest cement was the Regular Clear PVC cement. The cement that primer (negatively) affected the most was the Rain-R-Shine ® Medium Blue PVC cement.
Does primer soften plastic?
If primer penetrates and softens the plastic surfaces prior to the application of cement, then the inclusion of primer in the solvent welding process should achieve maximum fusion and strength.
Why do you need primer on PVC?
The purpose of primer is to begin the chemical reaction that softens PVC and to provide an even prepped surface for the solvent cement. As you may know, PVC joints are not glued together exactly, but fused through a chemical change. The softer the outer layer of your PVC, the better it will cement in your joint. This is how primer helps your joint strength.
What color is a plumbing primer?
In many states plumbing inspectors will look for primer and only pass you if they see liberal use on all joints. Most primers are a vibrant purple color so that its use is evident, but there are also clear primers.
Do you need primer for PVC joints?
