Hydraulic Pipe Networks
Calculate hydraulic and heating pipe networks
With this online tool you calculate hydraulic and thermal parameters of heating, district heating and pipe networks. The calculation supports design, analysis and optimisation of piping systems and is based on the open-source framework pandapipes.
The tool is suitable for engineers, specialist planners, building technicians and energy consultants who want to size and evaluate pipe networks efficiently.
What is pipe network calculation used for?
Correct hydraulic design is essential for energy-efficient and trouble-free operation of heating and district heating systems.
Typical applications:
- Heating systems
- District heating networks
- Industrial plants
- District and local heating networks
- Refurbishment of existing systems
- Hydraulic balancing
Which calculations are available?
- Pipe network calculation
- Pressure loss
- Volumetric flow
- Pipe diameter
- Flow velocity
- Heat losses of pipes
- Hydraulic balancing
- Pump sizing
- Heating circuit calculation
- District heating networks
- Ring networks
- Distribution networks
- Network analysis
How does the calculation work?
- Upload a network file or select a sample network
- Enable the desired calculation options
- Start the pipe network calculation
- Analyse the results
- Download the report
The evaluation provides all key hydraulic parameters for planning and optimising the pipe network.
JSON import and automatic conversion
When uploading a network file, the JSON is automatically converted into the format required for calculation. You do not need to convert the file manually.
Supported inputs:
- Calculation JSON of this tool (
pipeswithfrom/to,nodes,sinks) - Export from the Schema Editor (devices as
nodes, pipes asedges, version 2) - Typical third-party formats as a graph (
nodesplusedges/links/connectionswithsource/targetorfrom/to)
Missing hydraulic values (e.g. heat transfer coefficient, exact volumetric flows) are completed with sensible defaults or estimates. Conversion notes appear in the result notes.
What results are output?
- Pressure losses
- Volumetric flows
- Flow velocities
- Pipe dimensions
- Heat losses
- Pump power
- Hydraulic balancing
- Network statistics
- JSON report
Typical benefits
- fast pipe network calculation directly in the browser
- support for modern heating and district heating systems
- practical pipe sizing
- optimisation of energy consumption and pump power
- suitable for planning, modernisation and training
