AS4041 isn't just about the pipe wall thickness. It governs of metallic pressure piping systems. Unlike ASME B31.3 (process piping) or B31.1 (power), AS4041 is a unified code for general pressure piping, but with a strong lean toward high-energy fluids (steam, water, oil, gas) up to PN500 (~72.5 psi to ~7250 psi, but often higher by derivation).
: AS4041 sets out the mathematical formulas and safety factors used to determine pipe wall thickness, pressure ratings, and the effects of external loads like wind or seismic activity.
AS4041 is risk-informed – its requirements tighten as the product of pressure × diameter × fluid hazard increases.
AS4041 is an Autonomous System number assigned to Cogent Communications, a global Tier 1 internet service provider. Cogent Communications is a multinational company that provides internet connectivity, network services, and data center services to customers worldwide.
