Why is proper application of pipe joint compound important?

The proper application of pipe joint compound is crucial because it ensures an airtight seal in the joints between pipes. This seal is essential for preventing gas leaks, which can lead to safety hazards such as fires or explosions. When the pipe joint compound is applied correctly, it fills the gaps and imperfections within the threads of the pipes, creating a strong barrier against the escape of gas. A secure airtight connection also helps maintain system efficiency, ensuring that the gas supply remains consistent and reliable for heating applications.

While prevention of corrosion, providing insulation, and improving aesthetic appearance are important factors to consider in HVAC systems, they do not primarily address the function that pipe joint compound serves in ensuring safety and system integrity. Therefore, the focus on achieving an airtight seal is essential for the safe operation of gas heating systems.
