Pipe Expansion Calculator — Calculate Thermal Expansion in Pipes

Pipe Expansion Calculator

Calculate thermal expansion in pipes for plumbing, HVAC, and industrial applications. Determine expansion length, stress, and required compensation with our comprehensive calculator.

Step 1: Pipe Specifications

17

Material Expansion Coefficients

Steel: 11-13, Copper: 17, PVC: 70, CPVC: 66, PEX: 140, Aluminum: 23. Standard values shown based on selected material.

Step 2: Temperature Specifications

1.5

Thermal Expansion Formula

ΔL = α × L₀ × ΔT, where α is expansion coefficient, L₀ is original length, and ΔT is temperature change. For fixed pipes, expansion creates stress: σ = E × α × ΔT.
