What method is used to join PVC pipes using a bonding agent?

The method used to join PVC pipes with a bonding agent is known as solvent welding. This process involves the use of a specific solvent that softens the surface of the PVC material, allowing the pipes to fuse together seamlessly. When the solvent is applied, it breaks down the rigid structure of the PVC, creating a chemical bond as it evaporates and the surfaces of the pipes meld together. This results in a strong, permanent joint that is both leak-proof and able to withstand the pressures typically encountered in irrigation systems.

Other methods such as welding or mechanical fastening are generally not applicable for PVC pipes, as they require different materials and processes. Compression fittings can be used with various types of piping systems, but they do not involve a bonding agent like solvent welding does; instead, they create a seal through pressure. Thus, solvent welding is the most effective and reliable method for achieving strong joints in PVC piping systems.
