Only forged flare fittings shall be used in gas tubing systems?

In gas tubing systems, it is essential to use fittings that can withstand high pressure and provide a reliable, leak-free seal. Forged flare fittings are specifically designed for this purpose. The process of forging creates a dense and strong material that is more resistant to stress and cracking compared to other types of fittings, such as cast ones.

Using forged flare fittings enhances the integrity and safety of the overall gas system, ensuring that connections can handle thermal expansion and mechanical stress over time without failing. The standards set by safety authorities emphasize the importance of these fittings to ensure safe operation within gas systems, which justifies the assertion that only forged flare fittings should be utilized in such applications.

This focus on safety and reliability is why the statement is categorized as true. In contrast, other types of fittings may not meet the necessary strength and safety standards required for gas applications, making them unsuitable for use in these systems.
