Which joint is formed using solvent or solvent cement in thermoplastic piping?

The formation of a joint using solvent or solvent cement in thermoplastic piping is referred to as a Plastic Solvent Cement Joint. This type of joint is created by applying a solvent cement that chemically fuses the surfaces of the thermoplastic pipes, ensuring a seamless connection. The solvent interacts with the plastic material, softening it and allowing the two surfaces to bond together when pressed. This method is crucial for maintaining the integrity and leak-proof characteristics of the piping system.

The application of solvent cement provides a strong and durable joint that can withstand the pressure and stresses typically encountered in piping systems. Unlike mechanical joints, which rely on fittings and screws for assembly, or welded joints that require heat to join thermoplastic materials, the solvent cement method creates a permanent bond through a chemical reaction. Understanding this process is vital for ensuring proper installation and compliance with mechanical code requirements.
