Pressure Vessel
Design by Analysis
Designed for Compliance, Simulated for Certainty
Pressure Vessel Design by Analysis (DBA) is an advanced approach used to evaluate pressure vessels and related components through detailed finite element analysis. Unlike conventional rule-based design, DBA allows engineers to assess actual stress behaviour, deformation, plastic collapse risk, fatigue life and structural integrity under realistic loading conditions.
For high-pressure, high-performance or weight-sensitive pressure vessels, traditional design methods may be too conservative or may not fully capture complex geometry and load combinations. Design by Analysis helps validate vessel performance more accurately, support safer design decisions and reduce unnecessary material usage while maintaining compliance with ASME VIII Division 2 requirements.
RF Station provides pressure vessel design by analysis services to support design validation, life assessment, optimization and compliance preparation for pressure vessels, reactors and critical pressurized components.
