Pe Pipe Dimensions

Overview

Engineering reference data for Pe Pipe Dimensions in piping systems.

Key Formulas

Continuity

$A_1 v_1 = A_2 v_2$

Mass conservation in pipe flow.

Pressure Drop

$\Delta P = f \frac{L}{D} \frac{\rho v^2}{2}$

Darcy-Weisbach equation.

Pipe Area

$A = \frac{\pi D^2}{4}$

Cross-sectional area of a pipe.

Variables

Symbol	Description	Unit
$D$	Pipe diameter	m
$v$	Flow velocity	m/s
$\Delta P$	Pressure drop	Pa
$f$	Friction factor	—

Pressure Ratings

The PN (Pressure Nominal) grade indicates the maximum allowable operating pressure in bars for PE pipes with water at 20°C.

PE Pipe Dimensions (ISO 4427)

Nominal outside diameter and corresponding inside diameters for various pressure grades.

Pressure Unit Conversions

For reference, 1 bar is equivalent to:

• $10^5 \text{ Pa} = 100 \text{ kPa} = 0.1 \text{ N/mm}^2$
• $10.197 \text{ m H}_2\text{O}$
• $0.9869 \text{ atm}$
• $14.50 \text{ psi}$
• $750 \text{ mmHg}$
