Accurately determine the length change of unrestrained pipes subjected to temperature variations with our free online calculator. Essential for proper pipeline design, preventing stress and failure due to thermal expansion. Simply input material properties, initial length, and temperature changes to get instant, reliable results for various materials like steel, copper, or PVC.
Formula:
The formula for unrestrained pipe length change due to thermal expansion or contraction is:
ΔL = α × L × ΔT
Which can also be written as:
ΔL = α × L × (Tfinal - Tinitial)
Where:
- ΔL = Change in pipe length (e.g., meters, feet)
- α = Coefficient of thermal expansion of the pipe material (e.g., 1/°C or 1/°F)
- L = Original length of the pipe (e.g., meters, feet)
- ΔT = Change in temperature (Final Temperature - Initial Temperature) (e.g., °C, °F)
- Tfinal = Final temperature of the pipe
- Tinitial = Initial temperature of the pipe
Note: Ensure the units for the coefficient of thermal expansion (α) are consistent with the chosen temperature units.
