Introduction In the high-stakes world of industrial engineering, safety and compliance are non-negotiable. For any project involving high-pressure fluid or gas transport in Australia and beyond, one document stands as the technical bedrock: AS 4041 . Formally titled "Pressure Piping," this standard governs the design, materials, fabrication, installation, testing, and operation of pressure piping systems.
