Pipe Support Hanger Spacing and Pipe Wall Thickness

Table 1.0 suggests minimum pipe hanger spacing for use unless exceeded by the local authority having jurisdiction or engineering calculations. The primary factors determining pipe wall thickness are hoop stress caused by internal pressure, and longitudinal stresses caused by pressure, weight, and other sustained loads. Detailed stress calculations are seldom required for most pipe hanging applications because standard pipe has ample thickness to sustain the pressure and longitudinal stress caused by weight (assuming hangers are spaced in accordance with Table 1.0).

*Spacing does not apply where span calculations are made or where concentrated loads are placed between supports such as flanges, valves, specialties, etc.
