What is the maximum length between hangers for 1 inch sch 40 pipe?

The maximum length between hangers for 1 inch Schedule 40 pipe is 12 feet. This distance is specified to ensure proper support and stability of the piping system, preventing sagging or excessive movement that could lead to stress or damage over time. In sprinkler systems, maintaining the integrity of the piping is crucial for effective water distribution and overall system performance.

Each type of pipe and its diameter has specific filling distance requirements based on its material, pressure limits, and intended use. These requirements are established by industry standards, which aim to ensure safety and reliability in installation. For 1 inch Schedule 40 pipe, the 12-foot distance allows enough flexibility for installation while still providing adequate support.

Understanding these guidelines helps sprinkler fitters ensure that installations meet necessary building codes, which not only promotes safety but also efficiency in the system's operation.
