Selecting the correct pipe support span is an important aspect of piping design. You can use the online calculator below to calculate the pipe support span for copper nickel piping (Cu-Ni) based on maximum allowable stress or maximum permissible deflection. The maximum pipe support spacing is dependent on the maximum allowable deflection or sag in the piping and the maximum permissible longitudinal stress on account of the span. 

Pipe Support Span for Copper Nickel (Cu-Ni) Piping

Input the values below to calculate the pipe support span for Cu-Ni piping. Fields with * cannot be left blank.

The density of Copper Nickel (Cu-Ni) piping is taken as 8940 kg/m3 in these calculations. For complete background information on the derivation of the formulas refer to the article: Allowable Pipe Support Span Calculation.
