What type of fittings are typically used in gas pipe installations?

In gas pipe installations, threaded or soldered fittings are commonly used due to their effectiveness in creating secure, leak-proof connections. Threaded fittings allow for easy assembly and disassembly, which is particularly beneficial for maintenance and repairs, as they can be easily installed and removed without the need for specialized equipment. Soldered fittings, typically used in copper gas lines, create strong, permanent joints that are resistant to pressure and thermal movement, further enhancing system integrity.

This combination of threaded and soldered fittings is designed to accommodate the specific requirements of gas systems, ensuring safety and compliance with regulations. Other types of fittings, while they may be suitable in specific contexts, are less commonly used in standard gas installations. For instance, welded fittings are more often seen in high-pressure or industrial applications, whereas flanged joints are used where frequent disconnection is not necessary. Screwed fittings can be an alternative but are less favored compared to the broader application of threaded and soldered options in the context of gas piping.
