U-Bolts
In this section, U-bolts library can be created.
A U-bolt library is a JSON file with a name, related to a piping library, units, factors and a list of U-bolts.
The factors will multiply the allowable forces of the U-bolts during calculation based on the current level (B, C, D, T).
1. Organisation
On the left panel, you can create folders, sub-folders and U-bolt libraries.
The - button is used both for removing folders and libraries.
You can drag a file/folder on another folder.
2. U-bolt sizes
Click the + button (1) to add a new pipe size from the selected piping library or click the - button (2) to remove a size.
3. U-bolt
Click the + button (3) to add a U-bolt for a specific pipe size or click the - button (4) to remove one.
Types
| Property | Description |
|---|---|
| Fixed | blocked in all directions |
| Guide | blocked perpendiculary to the pipe |
Forces
For fixed U-bolts :
| Property | Description | Unit Metric | Unit USA |
|---|---|---|---|
| Fs | Prestressing force in the fixed U-bolt | kN | kips |
For guided U-bolts :
| Property | Description | Unit Metric | Unit USA |
|---|---|---|---|
| Fa | Allowable pulling force in the guided U-bolt | kN | kips |
| Fam | Allowable force in pulling direction (mid point) | kN | kips |
| Fbm | Allowable force in shear direction (mid point) | kN | kips |
| Fb | Allowable shear force in the guided U-bolt | kN | kips |
Curves
