What action should be taken if the gas piping is subjected to high pressure?

When gas piping is subjected to high pressure, utilizing welded joints is a critical action to ensure safety and integrity. Welded joints create a strong, permanent connection that can effectively withstand the stresses and potential leakage risks associated with high-pressure environments. This method of joining piping materials minimizes the possibility of failure at the joints, which is a primary concern when managing high-pressure gas systems.

The use of welded joints is particularly advantageous because it provides a continuous and gas-tight seal that is more robust compared to threaded or flanged connections. In high-pressure scenarios, the integrity of every joint is crucial as any weakness may lead to dangerous leaks or catastrophic failures.

In contrast, while increasing pipe size or using additional fittings may seem plausible solutions, they do not specifically address the need for joint integrity under high-pressure conditions. Additionally, reducing flow rate could alleviate some pressure but is not a direct method to ensure the physical resilience of the piping system itself. Therefore, when dealing with high pressure in gas piping, the focus on welded joints remains the best practice for ensuring safety and reliability.
