Overview

Engineering reference data for Identification Scheme Piping Systems 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	—

The ANSI A13.1 Standard defines pipe identification through color coding and letter sizing based on fluid hazards and pipe dimensions. Below are the specific classifications and guidelines extracted from the standard.

Color Scheme Classification

Pipes are color-coded according to the hazard level of the fluid they carry. The table below summarizes the classifications and associated color schemes.
