The standard provides a comprehensive framework for the structural design of metallic industrial piping. It is a under the European Pressure Equipment Directive (PED) 2014/68/EU , meaning that piping designed in accordance with its rules is presumed to comply with the essential safety requirements of the directive.

The standard is a critical document for engineers, designers, and manufacturers working with industrial metallic piping systems. As Part 3 of the broader EN 13480 series, it specifically addresses the design and calculation requirements necessary to ensure the mechanical integrity and safety of piping networks under various operating conditions. Overview of EN 13480-3

specifically dictates how to calculate the required wall thickness of pipes, the design of bends, tees, reducers, and the necessary calculations for flexibility analysis (expansion loops, stresses due to thermal expansion, etc.).
