Creating NPT Connections for Piping Fittings
Last Updated: May 7, 2007, By:LB
The best way to analyze NPT threaded piping fittings using FEA methods is with the pipe included in the analysis. Pressurizing the pipe transmits realistic stresses to the fitting body. Anchoring a pipe instead of the fitting produces much more realistic stresses and deflections.
Construction of the Pipes:
Any attempt to anchor faces or edges on this model would alter the deformed shape and the stresses measured. This method of including the pipes is simple and realistic.
This analysis method does not include the effects of thread shear stress on the connections. This can be calculated using Machinery Handbook formulas.
