Pipe Thermal Expansion Calculator

Linear Thermal Expansion Formula

All piping materials expand when heated and contract when cooled. If this movement is restricted by rigid anchors, the resulting thermal stress can destroy the pipe or equipment. That's why engineers design expansion loops or joints based on the thermal coefficient ($\alpha$).

Variables:

• $\Delta L$ = Change in length (Expansion).
• $L$ = Original length of the pipe (converted to inches in the calculator).
• $\alpha$ = Coefficient of thermal expansion for the specific material ($in/in/^\circ F$).
• $\Delta T$ = Temperature change ($T_{operating} - T_{install}$ in $^\circ F$).
