True or False: A screwed flange would be found on an 8 inch, 900 lb joint.

1. True

2. False

3. Not applicable

4. Commonly used

The correct answer is: False

A screwed flange is typically used in lower pressure applications and is constructed to provide a more lightweight and less robust connection. However, a joint rated at 900 lb is indicative of a higher pressure application typically associated with heavier and more durable flanges, such as welded or threaded flanges that are capable of handling the stress and integrity required for such conditions. In industrial applications, especially for pipelines and joints that are under significant pressure, the use of a screwed flange would not be appropriate. This is because a screwed flange can have limitations in its pressure rating and overall strength when compared to other types of flanges designed for high-pressure systems. Therefore, a screwed flange would not be a suitable choice for an 8 inch, 900 lb joint, making the statement false.
