Which method is commonly misnamed as gluing in PVC applications?

The method commonly misnamed as gluing in PVC applications is solvent welding. This terminology arises because the process involves applying a solvent, which chemically softens the surfaces of the PVC pipe and fitting to create a bond. The solvent penetrates the material, effectively merging the two surfaces when they are pressed together, resulting in a strong, seamless joint. This process is essential for ensuring the integrity of the system since it provides a leak-proof connection.

Unlike what's suggested by the term "gluing," solvent welding does not merely stick the pieces together with an adhesive; rather, it forms a chemical bond that is generally much stronger than the individual materials. Understanding this distinction is crucial for those working with PVC in irrigation systems, as a proper solvent weld ensures durability and functionality in the application.
