What is the purpose of heat fusion in piping systems?

The purpose of heat fusion in piping systems is to fuse thermoplastic surfaces by applying heat. This process involves heating the edges of the thermoplastic material until they soften and then bringing the surfaces together to form a bond. Upon cooling, the material hardens, creating a strong and leak-resistant joint that is integral to the integrity and functionality of the piping system.

This method is particularly advantageous for thermoplastic piping, as it creates a seamless connection that maintains the properties of the material, unlike joints that may be subject to leaks over time, such as those created with adhesives. Heat fusion eliminates the need for additional fasteners or solvents, simplifying the installation process while ensuring a robust and durable connection.

In summary, heat fusion is a critical technique in the assembly of thermoplastic piping systems, as it ensures strong, long-lasting joints that help maintain the overall reliability of the system.
