For a water mist system with 1½ in. stainless steel pipe, the minimum bending radius is:

Explanation:
In water mist piping, bends must be gentle enough to avoid deforming the pipe and to maintain smooth flow for proper mist generation. The minimum bending radius is two times the pipe diameter, which protects the pipe from kinking and minimizes flow disruption. For a 1½ in stainless steel pipe, that means a centerline bend radius of at least 3 inches. Bends tighter than this can deform the pipe and increase pressure loss or cause leaks, while larger radii are not required by the minimum standard.
