Adhesive used for joining nonmetallic piping?

• A. Solvent Cement
• B. Nonmetallic Pipe Materials
• C. American National Standard
• D. Revision Cycles

Answer: (A)

Solvent cement is the adhesive used for joining nonmetallic piping because it chemically welds plastic pipes (such as PVC and CPVC) to fittings. The solvent softens the plastic surfaces and, as the solvent evaporates, creates a strong, watertight bond that’s appropriate for the pressures in residential sprinkler systems. This is different from metal piping, which is joined by threading or welding, and from standards or cycles, which describe requirements rather than how to join pipes.
