What is the hanger spacing for threadable lightwall steel pipe sized 1" to 3"?

• A. 10 feet
• B. 12 feet
• C. 15 feet
• D. 18 feet

Answer: (B)

The correct spacing for hangers supporting threaded lightwall steel pipe sized from 1" to 3" is indeed 12 feet. This guideline is based on industry standards designed to prevent sagging and maintain proper alignment of the piping system, which is critical for both functionality and integrity. When spacing hangers, it is vital to ensure that the weight of the pipe, along with any contained liquid and potential thermal expansion or contraction, is properly supported. Spacing hangers too far apart can lead to excessive movement, which may cause leaks, pipe damage, or increased stress at the joints and fittings. The choice of 12 feet as the required spacing reflects a balance between maintaining adequate support and ensuring cost-effectiveness in installation. Hanger spacing requirements can vary based on the specific type of piping, its weight, and the operational conditions, but for lightwall steel pipe in this size range, the established standard is 12 feet. Thus, understanding these guidelines is important for ensuring compliance with safety and plumbing codes, as well as for the longevity of the sprinkler system.
