Pipe Rack Intersection

The secondary pipe rack intersection is shown below.

There is a right and a wrong way to set his location.

Although it may seem more uniform to set the secondary rack directly south of the main north/south rack during the plot plan development stage, following drawing also clearly shows why this should be avoided.

The lines heading north off the main east/ west rack restrict the lines from the south from entering this common area.

Therefore, the secondary rack should be shifted east one bay to eliminate the problem.
