What is the purpose of using gaskets in gas piping flanges?

Using gaskets in gas piping flanges is essential primarily for preventing leaks. Gaskets act as a seal between the flanges of the piping system, creating a tight barrier that stops gas from escaping at the joints. This is crucial for maintaining the integrity of the gas delivery system and ensuring safety, as leaks can lead to hazardous situations. The material and design of the gasket are chosen based on the pressures and temperatures expected in the gas system, ensuring that they can withstand operational conditions and provide a reliable seal.

While flow enhancement, aesthetics, and weight reduction could be considerations in different contexts, they do not pertain directly to the primary role of gaskets in this application. The focus on preventing leaks is vital, as gas systems must operate safely and reliably, making the use of gaskets a critical component in any well-designed gas piping installation.
