Data
The Data window lets you create all materials and all piping sections of the model.
It also lets you select one or more predefined specifications.
1. New project
When starting a new model, the Data window opens :
1.1 Material definition
Let’s define a new material.
Click on the + button and enter the description of the new material (Ex : My material).
A new name has been created for this material (Ex : 100).
Click the - button (next to Name) to remove it.
Define the description, the type, the temperature max, the density and the Poisson’s ratio.
Click the + button (next to Properties) to add a new row of properties for a specific temperature or click the - button (end of row) to remove one.
| Property | Description | Unit Metric | Unit USA |
|---|---|---|---|
| Max. temperature | Temperature max | °C | °F |
| Density | Density | kg/m³ | lb/ft³ |
| Poisson | Poisson’s ratio | - | - |
| EH | Modulus of Elasticity | kN/mm² | 10^6.psi |
| EX | Thermal Expansion | 10^-6.mm/mm/°C | 10^-6.in/in/°F |
| SH | Non-Class 1 Allowable Stress | N/mm² | ksi |
| SY | Yield Stress | N/mm² | ksi |
| SU | Ultimate Tensile Stress | N/mm² | ksi |
| SM | Class 1 Allowable Stress | N/mm² | ksi |
| CR | Creep | N/mm² | ksi |
| GH | Shear Modulus (composite only) | kN/mm² | 10^6.psi |
| E2 | Circumferential Modulus of Elasticity (composite only) | kN/mm² | 10^6.psi |
| CO | Thermal Conductivity (Class 1) | kJ/hr/m/°C | btu/hr/ft/°F |
| DI | Thermal Diffusivity (Class 1) | mm²/s | ft²/hr |
See Units for more information.
ATTENTION, temperatures must be entered in ascending order!
Properties of High Density Polyethylene materials (HDPE) also depend on load duration. The properties are built-in for 5 different specifications:
- ISO : EN 15494:2015 with coefficient = 1.25
- ASTM : ASTM with factor = 0.63
- ASME : ASTM with factor = 0.5 (= values given in Appendix XXVI)
- EDF1 : guide EDF D305914006648 [E]
- EDF2 : guide EDF D305921021240 [A]
The user has to enter the density, Poisson’s ratio’ and thermal expansion coefficient, which are supposed to be constant.
To save time, you can also directly select a material from database :
Click on the Database button, select a Library and a Material. The tables will be filled automatically :
Only libraries with Target = Piping will be shown !

1.2 Piping definition
To add new pipe sizes, click on + button (1) and give it a name (Ex : 4”).
Each size exists in different schedules. click on + button to add schedules :
| Property | Unit Metric | Unit USA |
|---|---|---|
| Schedule | - | - |
| Outside diameter | mm | in |
| Thickness | mm | in |
| Linear mass | kg/m | lb/ft |
To know the UNIT of a property, just let the mouse over the property name.
For example : mm for the Outside diameter
ATTENTION, the name of the pipe size is very important (Ex : 4”). It will be used as a reference for all other piping elements.
ATTENTION, the sizes must be defined in an ascending order.
To add bend properties for each pipe size, click on + button and select a pipe size :
Standard radius and mass can be entered :
| Property | Unit Metric | Unit USA |
|---|---|---|
| Long radius | m | ft |
| Small radius | m | ft |
| Mass | ton | kips |
ATTENTION, for a better readability, we recommend to enter the sizes in ascending order.
To add reducer properties for each pipe size, click on + button and select a pipe size :
Click on + button (next to Mass) to add all possible reduction from the current size to a smaller one.
Length and mass can be entered :
| Property | Unit Metric | Unit USA |
|---|---|---|
| Length | m | ft |
| Mass | ton | kips |
ATTENTION, for a better readability, we recommend to enter the sizes in ascending order.
To save time, you can also directly select a pipe size from database (2) :
Select a Library, a Pipe size and a Schedule. The tables will be filled automatically :
Click here for more information about creation of library of piping elements.
Finally, you can define the sections of the model by defining pairs of Piping size/Material + special properties of the project.
Click to + button and select pipe sizes (Ex : 4”) :
For each size, define the schedule and the material. A pipe knows now its section and its material.
Select then the node connections of the pipe, which depend on the material :
Steel
- None
- Butt weld - flush
- Butt weld - as welded
- Fillet weld
- Full fillet weld
- Threaded
- Brazed
Composite
- None
- Bell and spigot adhesive bonded
- Bell and spigot adhesive bonded with laminated fiberglass overlay
- Bell and spigot gasket with laminated fiberglass overlay
- Butt and strap
HDPE
- None
- Concentric fabricated reducer
- Thrust collar
- Electrofusion coupling
You may define the mismatch for butt-weld as welded connections, and the fillet length for fillet weld connections [mm or in].
Select then the Long weld type of the pipe between :
- None
- Butt weld flush (steel only)
- Butt weld as welded (steel only)
Based on this property, define the Long weld mismatch [mm or in].
Other properties :
| Property | Unit Metric | Unit USA | Default |
|---|---|---|---|
| Linear mass + insulation | kg/m | lb/ft | Linear mass of the pipe |
| Insulation thickness | mm | in | 0 |
| External corrosion | mm | in | 0 |
| Internal erosion | mm | in | 0 |
| Bend thickness | mm | in | Thickness of the pipe |
1.3 Spec driven mode
Another way to define Materials and Piping elements is to use a predefined Specification.
The goal of a specification is to supervise the engineer’s work by predefining all piping elements, sections, materials, bend radius, reducer lengths, tees…
Click to + button and select a specification :

Now, you can use these 2 dropdown lists to select the current section :
