Pipe Thermal Expansion Stress Calculator
Pipe thermal expansion stress calculation is crucial for ensuring the safety and longevity of piping systems. It involves determining the stress induced in a pipe due to thermal expansion…
How to Use This Calculator
- Enter the pipe’s diameter, length, and temperature change.
- Select the material of the pipe.
- Click “Calculate”.
Formula & Methodology
The formula used in this calculator is based on the following equation:
σ = α * E * ΔT * (1 – μ) / (1 – μ * μ)
Where:
- σ is the stress,
- α is the coefficient of thermal expansion,
- E is the modulus of elasticity,
- ΔT is the temperature change,
- μ is Poisson’s ratio.

What is Poisson’s ratio (μ)?
Poisson’s ratio is a measure of how much a material contracts in the transverse direction when it is stretched in the longitudinal direction. It is a dimensionless parameter that ranges from -1 to 0.5 for most materials.
