Description
Pipe-run is a component that is available within all design scopes, it forms a fragment of the piping system between two junctions where the flow can be changed. Within the following scopes: Heating systems, Cooling systems and Water supply systems a Pipe-run may consist of multiple segments (vertical and horizontal), separated by pipe-run division points. It can be drawn as a single pipe-run or as a Pipe-runs pair/ Three pipe-runs. Within the Sanitary drainage systems scope a Pipe-run of the Gravity sewerage or Ventilation conduit type always consists of a single segment.
It is possible to specify default values for Distance from floor (set in storey data). In addition, the user has full control over the arrangement of the pipe-runs using dedicated editors available in the 2D editor and 3D view windows.

Examples of use
Pipe-run dividing point and midpoint
- One Pipe-run may consist of several sections connected by means of midpoints.
- Two Pipe-run are separated by a pipe-run dividing point - a junction/node.
- Any number of additional points can be placed on a Pipe-run using the context menu and functions available there: Insert midpoint and Insert dividing point.
- Midpoints can be changed into dividing points and vice versa:
Default distances between pipe-run and floor and between pipe-run and ceiling
In the Data table window it is possible to specify for a Storey the default distance from the floor separately for each Pipe-run type component and the default distance from the ceiling (for arranging ceiling panels) in the following fields:
- for Heating systems:
- ΔHpipe-run,,S and ΔHpipe-run,, R - Default distance of pipe-runs (except for supplying ceiling panels) from the floor specified in storey data: S - supply, R - return.
- ΔHpipe-run,pan. - Pipe-run to ceiling distance - ceiling panel distribution.
- for Water supply systems:
- ΔHpipe-run,,HW - Default pipe-run distance from the floor (set in storey data) for Pipe-run: Hot water.
- ΔHpipe-run,,CW - Default pipe-run distance from the floor (set in storey data) for Pipe-run: Cold water.
- ΔHpipe-run,,Circ - Default pipe-run distance from the floor (set in storey data) for Pipe-run: Circulation.
4. Default pipe-run distance.
Pipe-run laying distance
- The Distance between pipe-runs can be specified for Pipe-runs pair/Three pipe-runs in the Data table window. After each component inserted, the last specified Distance is memorized.
5. Distance for Pipe-runs pair.
Determining the vertical alignment of the pipe-runs - Heating systems, Cooling systems and Water supply systems
The alignment and elevations of a pipe-run can be managed using dedicated editors that are displayed after selecting a component in the 2D editor and 3D view window:
- shows the elevation of the pipe-run end.
- shows the elevation of the section.
- shows the distance between pipe-run point/section and floor. 
6. Display of the elevations of a Pipe-run in the 2D editor and 3D view window.
InstalSystem 5 offers three methods of managing the alignment of a distribution system that allow the most convenient method to be selected to suit the individual design context. The method should be selected in the Vertical layout of pipe-run editor in the Data table window for the Pipe-run:
- Auto mode:
- Editors showing the elevation of pipe-run ends and distance from the floor are greyed out and the values presented cannot be modified.
- The value of Elevation can be modified in the Data table window for the Pipe-run and this change automatically modifies the values in all editors for the selected component.
- Manual elevations of sections mode:
- In the editors available in the 2D editor and 3D view window it is possible to specify the elevation and distance from the floor of a pipe-run section.
- Based on the difference between the specified section elevations, vertical pipe-runs are automatically created.
- Editors of pipe-runs connected on one end to terminal units are greyed out and these cannot be edited.
- The 2D editor and 3D view windows do not display editors with elevations of vertical sections of pipe-runs.
7. Vertical layout of pipe-run - Manual elevations of sections.
- Manual elevations of nodes:
- Editors in the 2D editor and 3D view window enable specifying the elevations and distance from the floor of the ends of a Pipe-run section.
- Vertical sections of pipe-runs are NOT automatically created - the entire pipe-run layout is controlled by the user.
- Editors of pipe-runs connected on one end to terminal units are greyed out and these cannot be edited.
8. Vertical layout of pipe-run - Manual elevations of nodes.
Attention! Every change of elevations and modification of Pipe-run layout requires running a Check connections operation available on the Main tools bar in section Calculations.
Determining the vertical alignment of pipe-runs - Sanitary drainage systems
The elevations and gradient of a pipe-run can be managed using dedicated editors that are displayed after selecting a component in the 2D editor and 3D view window:
- shows the elevation of pipe-run sections, values presented in the editors correspond to the fields: Elevation of first node and Elevation of second node available in the Data table window of the component.
- shows the gradient of the pipe-run and corresponds to the Real gradient field available in the Data table window of the component.
5. Display of elevations and gradient of a Pipe-run in the 2D editor and 3D view window.
When laying the pipe-runs, they adopt a gradient according to the direction of flow to the sewage outlet, taking into account the settings made in the General data window on the Sanitary drainage systems/ Calculation standards and options tab:
- The default minimum gradients specified for the selected component locations are adopted. In addition, the pipe-run laying algorithm takes into account the elevation and gradient values specified by the user in the editors described above.
- The Method of conducting of branches is taken into account:
- for the towards the floor setting - pipe-runs are arranged towards the terminal units with minimum gradient. If necessary, vertical pipe-runs at the terminal units are added taking into account the value specified in Distance from the floor of the connection points to the stack field,
- for the towards the wall setting - pipe-runs are arranged downstream of the terminal unit with the gradients specified in the General data window, and they are then connected to the collective branch by means of a vertical pipe-run (if drawing it is necessary for the continuity of the system).
9. Alignment of pipe-runs - Sanitary drainage systems.
Laying pipe-runs in a single vertical plane
- Appropriate setting of elevation values of individual types of pipe-runs in the Data table window for a Storey in sections: Heating/Cooling or Water supply and specifying the minimum value in the Distance field in the Data table window of a Pipe-runs pair/ Three pipe-runs, enable aligning pipe-runs in one vertical plane, e.g. in a wall one over the other.
Inclined pipe-runs
- The Vertical layout of pipe-run function enables full control over the alignment of a pipe-run, which, together with the possibility of marking points on a component, makes it possible to draw inclined pipe-runs and to design the connections of systems located on inclined attic elements.
Basic rules of connecting pipe-runs to other system components
The Main tools bar in the Edit group offers three methods of automatic connecting of terminal units to the pipe-run arrangement drawn beforehand:
- Automatically connect terminal units - connects selected Pipe-run components and terminal units within the following scopes: Heating systems, Cooling systems and Water supply systems.
- Automatically connect terminal units in tee system - connects selected Pipe-run components and terminal units of a water supply system in a tee joint system.
- Connect in series - connects Ceiling panel or Wall panel components selected beforehand using a Serial connection type pipe-run. For more information, see: Designing panel (ceiling, wall) heating/cooling systems.
For all components connected to a system (e.g. Terminal unit, Mixer, Manifold), a horizontal pipe-run section 5cm long is drawn, followed by a bend to arrive at the defined elevation of the Pipe-run. Exceptions from this rule:
- Connection of a Radiator with an integrated angled valve - a horizontal pipe-run section is drawn of a length of: Distance from wall + 5cm, followed by a bend to arrive at the defined elevation of the Pipe-run.
- Connection of a Water supply faucet - a horizontal pipe-run section 1cm long is drawn, followed by a bend to arrive at the defined elevation of the Pipe-run.
11. Connection of a Water supply faucet. - Connection of a Riser - if the pipe-run connection is made directly, with no midpoints, the pipe-run elevation adopted corresponds to the actual value in accordance with the data given in the Data table window of the Pipe-run.
- Connection of a Mixer/Control loop - the Automatically connect terminal units operation results in connecting only the points that are on the primary side of the Mixer.
Pipe-run in auto mode
When pipe-runs have been drawn in a project in such a way that within one storey there are vertical pipe-runs (created not by inserting a Riser, but by connecting four pipe-runs or pipe-run pairs), pipe-runs to be connected to these vertical sections are subject to defined drawing rules:
- when drawing components with the Auto mode enabled, the Pipe-run is connected to the vertical pipe-run with its elevation retained.
- when connecting a pipe-run to pipe-runs the coordinates of which overlap, the Pipe-run drawn is connected to the component of the lowest elevation.
12. Connection to vertical pipe-runs.
No-flow and bypass pipe runs
No medium flow pipe-run
- Is used in Water supply systems, Heating systems and Cooling systems for drainage and removal of condensate and is available in the appropriate project scopes.
13. No medium flow pipe-run.
- One end of this type of pipe should be connected to a standard pipe-run, the other end to one of the following elements:
- Expansion vessel;
- Safety valve;
- Outlet of no-flow pipe-run.
- Can be fitted with Shut-off valves.
By-pass pipe-run
- Is used in Heating systems and Cooling systems for redirecting the medium flow and is available in the appropriate project scopes. Is not used for mixing (is a kind of No medium flow pipe-run).
14. By-pass pipe-run. - Can be connected to Pipe-run (supply) and Pipe-run (return) or two pipes of the same type (valve bypass).
- Can be fitted with the several types of valves, including Shut-off valves and Relief valve.
