The correct answer is Vanstone. A Vanstone edge is a specific type of edge configuration that is often seen on round pipes, particularly in industrial applications. This type of edge is designed to facilitate the connection of the pipe to a companion flange, allowing for a secure and reliable joint while also making it easier to assemble and disassemble the piping system.

The dimensions of 3/8"-1/2" turn on the edge serve to provide a predetermined space for the companion flange to fit snugly, ensuring that the connection can handle the pressures and stresses typically encountered in industrial environments. The design of the Vanstone edge helps to differentiate it from other edge types, which may not provide the same advantages in terms of ease of assembly and sealing capabilities.

Other choices, while related to sheet metal and piping, do not specifically describe the edge configuration that supports the use of a companion flange in the context provided. By focusing on the connection style and application, Vanstone edges come to the forefront as the most appropriate choice for this scenario.
