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.
