Section 4 of the HITS report is probably the most important one. This section is really a printout of the internal data structure that represents the piping network. This data is organized on the basis of topos.

A topo is a construction used to group the data representing the pipeline topology. By definition a topo is a string of piping that starts at a network endpoint or a branch point and ends at a network endpoint or another branch point. A pipeline network may consist of a single topo or dozens of topos depending upon its configuration.

The line in the figure above consists of one topo because it does not contain any branch points. The beginning of the topo is a line endpoint as is the end of the topo.

The line in the figure above contains two topos due to the branch component in it (the tee). The first topo consists of the line from endpoint 1 to endpoint 2 (the header of the pipeline). The second topo consists of the piping from the center of the tee to line endpoint 3.

The line in the figure above contains three topos because there are two branches in it. The first topo again consists of the line from endpoint 1 to endpoint 2. The second topo consists of the line from connect point 1 of weldolet 1 to endpoint 3. The third topo consists of the line from connect point 1 of weldolet 2 to endpoint 4.
