Primarily covers vessels made of steels according to EN 13445-2 .
Generally uses lower safety factors than ASME VIII, leading to thinner walls for similar pressures. EN 13445-3
It is a harmonized standard under the European Pressure Equipment Directive (PED) . Primarily covers vessels made of steels according to
Annex B provides the "Direct Route" for design using Finite Element Method (FEM) analysis for complex geometries. Scope and Application Annex B provides the "Direct Route" for design
is the European standard that specifies requirements for the design of unfired pressure vessels . It provides formulas, calculation methods, and rules to ensure the structural integrity of pressure-bearing components under various loading conditions. Key Content & Sections
