Is a screwed flange found on an 8-inch, 900lb joint?

In the context of piping systems, a screwed flange is designed specifically for lower pressure applications and is typically used in smaller diameter pipes. An 8-inch, 900lb joint refers to a significant pressure rating that generally requires stronger joining methods such as welded flanges rather than threaded or screwed flanges. The 900lb rating indicates a high pressure, which necessitates a more robust connection to ensure safety and structural integrity.

Screwed flanges are not typically utilized for high-pressure piping systems due to their limitations in strength compared to welded connections. Therefore, a screwed flange would not be appropriate or found on an 8-inch, 900lb joint. This is why the statement is considered false.
