The EBAA Iron restraint calculator is an essential utility for engineers, technicians, and professionals in the piping industry. Its primary purpose is to calculate the minimum restrained length of a pipe, ensuring it remains secure and stable under different conditions. This calculation is crucial in preventing potential accidents and damages that could result from pipe movement or failure.
The formula used in the EBAA Iron restraint calculator is as follows:
Formula EBAA Iron restraint calculator
L = Sf • P • A • Tan (θ/2) / (Fs + ½Rs)
Where:
- L: The calculated minimum restrained length of the pipe.
- P: The internal pressure.
- A: The cross-sectional area of the pipe (in square meters).
- θ: The bend angle (in degrees).
- Fs: The frictional resistance acting on half the pipe diameter.
- Rs: The bearing resistance acting on the pipe.
- Sf: The safety factor.

General Terms Table
| Term | Description |
|---|---|
| Internal Pressure (P) | The pressure inside the pipe. |
| Cross-Sectional Area (A) | The area of the pipe’s cross-section (in square meters). |
| Bend Angle (θ) | The angle at which the pipe is bent (in degrees). |
| Frictional Resistance (Fs) | The resistance to movement caused by friction. |
| Bearing Resistance (Rs) | The resistance to movement caused by bearing. |
| Safety Factor (Sf) | A factor that ensures additional safety in the calculation. |
Example of EBAA Iron restraint calculator
Let’s illustrate how to use the EBAA Iron restraint calculator with an example:
Suppose you have a pipe with the following parameters:
- Internal Pressure (P) = 200 kPa
- Cross-Sectional Area (A) = 0.1 m²
- Bend Angle (θ) = 45 degrees
- Frictional Resistance (Fs) = 10 N
- Bearing Resistance (Rs) = 15 N
- Safety Factor (Sf) = 1.5
Using the formula mentioned earlier, you can calculate the minimum restrained length (L) to ensure the pipe’s stability under these conditions.
