Calculations & Checks
How the software calculates, what it checks, and how to read every result.
-
How Pihasa Assistant Calculates
What the software calculates, what it checks, and what it leaves to the engineer. The starting point for understanding any result on a support datasheet.
-
Units, Loads and Movements
The conventions behind every field on a support datasheet — which units apply, what each load means, and how movement signs are interpreted.
-
Hot Load, Cold Load and Variability
Why the load on a variable spring changes as the pipe moves, what variability measures, and how to bring it down when a selection exceeds the limit.
-
Travel and Travel Reserves
How the software positions a spring within its travel range, what the recommended range is for, and when to define travel reserves of your own.
-
Temperature and Material Quality
Why the same clamp carries less load at 500 °C than at ambient, how the software corrects for it, and what the two separate checks on material quality are.
-
What the Software Checks
The full list of verifications Pihasa Assistant runs on a support, what each one protects against, and why passing them all is not the same as a validated design.
-
Hydrostatic Test Check
Why the hydrostatic test is a separate load case, which components the software checks against it, and what to do when a support fails.
-
Vertical Deviation Angle
What the deviation angle measures on a hanging support, why the software warns about it, and which support types it does not apply to.
-
Rods, Take-outs and Weights
How the software turns elevations into a rod length, when a rod is split into sections, and how assembly weights and the bill of materials are built.
-
Troubleshooting Calculation Warnings
What each warning on a support datasheet means, why it appeared, and the options for resolving it — from no valid model found to exceeded lateral load.
