Pe Temperature Pressure Rating

Overview

Engineering reference data for Pe Temperature Pressure Rating in material science and properties.

Key Formulas

Stress

$\sigma = \frac{F}{A}$

Force per unit area.

Strain

$\varepsilon = \frac{\Delta L}{L_0}$

Change in length per original length.

Hooke's Law

$\sigma = E \varepsilon$

Stress proportional to strain in elastic region.

Thermal Expansion

$\Delta L = \alpha L_0 \Delta T$

Length change due to temperature.

Variables

Symbol	Description	Unit
$\sigma$	Stress	Pa
$\varepsilon$	Strain	—
$E$	Young's modulus	Pa
$\alpha$	Thermal expansion coefficient	1/°C
$\Delta T$	Temperature change	°C

Temperature-Pressure Rating Data

Practical Example: Water Supply System

Consider a water supply system with an area pressure of 4 bar. Using the table above:

• For cold water (temperature ≤20°C), select PE pipes with *PN 6 (maximum operating pressure 6.0 bar at 20°C).
• For hot water (temperature ≤50°C), select PE pipes with *PN 16 (maximum operating pressure 8.0 bar at 50°C).
