Guys,

I have one question to clarify.
In order to keep model size reasonable for a branch pipe analysis ,can an existing main header pipe connected may be ignored in the model with limiting the branch point as a fixed anchor point.

For example, considering the analysis of anew 4" branch line connected to the large size existing header pipe 16",the tee/ branch point can be assumed as a fixed point and approximated to an anchor.

This approach may not affect the accuracy for the stress analysis and may suffice for the intended requirement.Is this approach be true.


Moreover , if the above approach is OK then is there any rule of thumb on restriction for header/branch pipe size ratios where this assumption can be reasonbaly applied.

Is there any other factor governs on this assumption as well.

Thanks.
