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 micro-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 micro-editors that are displayed after selecting a component in the 2D editor and 3D view window:

  • Rzedna konca dzialki-new3.png - shows the elevation of the pipe-run end.
  • Rzedna-odcinka-new2.png - shows the elevation of the section.
  • Odleglosc-od-podlogi-new2.png - 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 micro-editor in the Data table window for the Pipe-run:

  • Auto mode:
    • Micro-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 micro-editors for the selected component.

  • Manual elevations of sections mode:
    • In the micro-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.
    • Micro-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 micro-editors with elevations of vertical sections of pipe-runs.
      7. Vertical layout of pipe-run - Manual elevations of sections.

  • Manual elevations of nodes:
    • Micro-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.
    • Micro-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.

      The following video shows the joint use of the functions described above.

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 micro-editors that are displayed after selecting a component in the 2D editor and 3D view window:

  • Editor drainage.png - shows the elevation of pipe-run sections, values presented in the micro-editors correspond to the fields: Elevation of first node and Elevation of second node available in the Data table window of the component.
  • Editor 2drainage.png - shows the gradient of the pipe-run and corresponds to the Real gradient field available in the Data table window of the component.
    9. 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 micro-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).
      10. 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:

11. Connecting panels in an attic.


  • 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.
    12. 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.
    13. Connection to vertical pipe-runs.

No-flow and bypass pipe runs

No medium flow pipe-run

  • May be used in Water supply systems, Heating systems and Cooling systems for draining, manual venting etc., and is available in the relevant project scopes.
    14. 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 relevant project scopes. Does not provide mixing of supply to return or vice versa in designing stage, acts rather like a kind of No medium flow pipe-run.
    15. By-pass pipe-run.

  • Can be connected to Pipe-run (supply) and Pipe-run (return) or two pipes of the same type (when used to bypass a valve).
  • Can be fitted with the several types of valves, including Shut-off valves and Relief valve.
