Which term describes joining PVC pipe using solvent?

• A. Solvent welding
• B. Glue bonding
• C. Mechanical joining
• D. Soldering

Answer: (A)

Solvent welding explains the process of joining PVC pipe with a solvent. This method uses a solvent-containing cement that softens the outer surface of the plastic so the pipe and fitting can fuse together as the solvent evaporates. The result is a single, continuous plastic joint that’s watertight, which is why it’s the standard technique for PVC in irrigation and plumbing. Glue bonding would imply an adhesive bond, which doesn’t chemically fuse the PVC the same way and isn’t the typical method for these plastics. Mechanical joining relies on fittings, clamps, or fasteners rather than dissolving and fusing the material. Soldering involves melting metal and isn’t used on PVC. So, the term describing joining PVC pipe using solvent is solvent welding. Remember to follow proper safety and curing times when using solvent cement.
