What is the characteristic finish of all flanges with a serrated or grooved design?

• A. Spiral design
• B. Flat surface
• C. Textured surface
• D. Rough finish

Answer: (A)

The characteristic finish of all flanges with a serrated or grooved design is a spiral design. This design enhances the sealing capability when two flanges are bolted together. The serrated or grooved texture creates multiple tight points of contact, allowing for better compression of the gasket material placed between the flanges. This configuration is particularly effective for preventing leaks in piping systems, as it provides a larger surface area for the gasket to grip. Understanding the specific design features of flanges is crucial in ensuring their proper application in various systems, where pressure and thermal expansion can cause regular flat surfaces to fail in sealing. The spiral or serrated design is intentionally engineered to maintain integrity under challenging conditions, which is why it is the defining feature of these types of flanges.
