For vessels subjected to external pressure or vacuum conditions, structural instability must be evaluated. The code provides explicit geometric factors and material charts to determine the allowable circumferential and longitudinal compressive stresses. Protection Against Cyclic Loading (Fatigue)

The PDF contains mandatory appendices that provide specific guidance on: at elevated temperatures.

: Division 2 rules cover only vessels to be installed in a fixed location for a specific service. The user who prepares or causes to be prepared the design specifications retains operation and maintenance control during the useful life of the vessel.

The is the global benchmark for pressure equipment design. While Division 1 focuses on a strict "design-by-rule" philosophy, Division 2 introduces advanced engineering concepts that permit higher allowable stress intensities. Key Purpose and Scope

Following recent code updates, Division 2 is split into two distinct classes:

The standard document is divided into nine major parts, structured to guide the workflow from material selection to final hydrotesting: : General Requirements Part 2 : Responsibilities and Duties (User and Manufacturer) Part 3 : Material Requirements Part 4 : Design by Rule Requirements Part 5 : Design by Analysis Requirements Part 6 : Fabrication Requirements Part 7 : Inspection and Examination Requirements Part 8 : Pressure Testing Requirements Part 9 : Pressure Relief Devices Integration with Finite Element Analysis (FEA)

Contains formulas for standard geometries (shells, heads, nozzles) under internal or external pressure.
