ASME Design and Analysis to B&PV and Power & Process Codes

ASME Design and Analysis of Equipment to Boiler & Pressure Vessel (B&PV) Code and Power (B31.1) & Process Piping (B31.3) Code. This Includes (Stress, Buckling, Thermal, Vibration, Fatigue and Fracture) Finite Element Analysis.

ASME Section VIII provides guidelines for pressure vessel design, analysis and construction, including tanks, boilers and heat exchangers. We provide both ASME BP&V Section VIII Division 1 (Closed-Form Design-By-Rule Methods) and ASME BP&V Section VIII Division 2 (Design-By-Analysis). The table below highlights a few key differences.

ASME Fatigue Design / Analysis

Fatigue (from cyclic loading) is one of the most frequent causes of failure in pressure vessels, piping and process equipment. A vibrating component or system often leads to fatigue – which eventually leads to equipment malfunction, or catastrophic failure. Fatigue cracks usually initiate at the surface, and for this reason, the condition of the surface and the environment are important factors influencing fatigue behaviour. Fatigue design / analysis is performed per ASME Section III Class 1 and Section VIII Division 2.
