What thickness of steel is required for pipe connectors that have a diameter greater than 16 inches?

26 gauge (0.019)
24 gauge (0.024)
22 gauge (0.029)
16 gauge (0.056)

The correct answer is: 16 gauge (0.056)

The requirement for pipe connectors with a diameter greater than 16 inches specifies the use of 16 gauge steel, which is 0.056 inches thick. This thickness is necessary to ensure structural integrity and safety under various operational conditions, including the high temperatures and pressures these systems may experience. Using a thicker gauge steel helps to prevent issues such as warping, deformation, or failure due to stress. It also contributes to better durability and a longer lifespan for the connectors, ensuring they can handle the demands of the system effectively. While the other options represent lesser gauges, they do not meet the necessary thickness requirements for larger diameter applications, which is why 16 gauge is the correct choice for achieving optimal performance and safety in this context.
