Which of the following is NOT a feature of a Van Stone flange?

A Van Stone flange is designed specifically to facilitate the connection of pipes, allowing for some degree of misalignment without compromising the seal of the joint. This feature makes it an attractive choice for various piping systems, particularly in installations where precise alignment is challenging.

Additionally, one of the advantages of a Van Stone flange is its ease of disassembly. The design allows for quick access for maintenance or replacement of components, making it more user-friendly in environments where frequent disassembly might be necessary.

Moreover, Van Stone flanges are designed to promote flow efficiency within the piping system. Their shape and structural design help reduce turbulence as fluids or gases pass through, enhancing the overall performance of the system.

While the correct choice indicates that electrical conductivity is not a feature of a Van Stone flange, it is essential to understand that flanges are generally crafted from various materials, such as metals or plastics, which can vary in their electrical conductivity depending on their composition. However, the Van Stone flange itself does not inherently emphasize or incorporate a feature related to electrical conductivity as a primary function, unlike the other options which highlight integral design benefits.
