Thermal Expansion Calculator

Thermal expansion can be compensated for with deflection legs, particularly in above-ground installations of PE piping systems.

Our Thermal expansion calculator will identify how much your pipeline is going to expand and contract, and what you should allow for with deflection legs.

When to Use This Thermal Expansion Calculator?

  • Calculate how much the HDPE pipe will expand or contract with temperature changes
  • Design systems that allow for movement due to thermal expansion
  • Prevent stress, buckling, or misalignment in long pipe runs
  • Plan for expansion loops, offsets, or anchors
  • Ensure your installation meets thermal movement requirements
