Overview

Engineering reference data for Wrought Steel Pipe Bursting Pressure in material science and properties.

Key Formulas

Stress

σ=FA\sigma = \frac{F}{A}

Force per unit area.

Strain

ε=ΔLL0\varepsilon = \frac{\Delta L}{L_0}

Change in length per original length.

Hooke's Law

σ=Eε\sigma = E \varepsilon

Stress proportional to strain in elastic region.

Thermal Expansion

ΔL=αL0ΔT\Delta L = \alpha L_0 \Delta T

Length change due to temperature.

Variables

Symbol Description Unit
σ\sigma Stress Pa
ε\varepsilon Strain —
EE Young's modulus Pa
α\alpha Thermal expansion coefficient 1/°C
ΔT\Delta T Temperature change °C

Pressure Ratings by Pipe Schedule

The bursting pressures are calculated using Barlow's formula. Working pressures are derived by applying a *safety factor of 8 to the bursting pressure values.

Working Pressure=Bursting Pressure8\text{Working Pressure} = \frac{\text{Bursting Pressure}}{8}

Standard Weight (STD) — Schedule 40

Extra Strong (XS) — Schedule 80

Double Extra Strong (XXS)
