What is the wall thickness of a 6" Schedule 40 pipe?

The wall thickness of a 6" Schedule 40 pipe is indeed 0.280 inches. This thickness is standardized according to the specifications set out by the American National Standards Institute (ANSI) and is commonly referenced in piping applications.

Schedule 40 is a designation that indicates the thickness of the pipe wall, and this thickness can vary depending on the nominal pipe size. For a 6-inch nominal pipe size, the established thickness of 0.280 inches is specifically designed to provide a balance of strength and weight, making it suitable for various applications, including residential plumbing and industrial systems.

Understanding pipe schedules is crucial for engineers and technicians working with high-pressure applications, as utilizing the correct wall thickness can impact the overall safety and integrity of a piping system. The other options do not correspond to the standardized wall thickness for a 6" Schedule 40 pipe, reinforcing the importance of familiarizing oneself with the relevant standards for proper installations.
