Fatigue Analysis Of Process Equipment Using Finite Element Method
FATIGUE ANALYSIS OF PROCESS EQUIPMENT USING FINITE ELEMENT METHOD OBJECTIVE A significant supplier of process equipment and pressure vessels requested CADE’s services to perform design validation for fatigue of a process reactor, aimed to be installed in a petrochemical plant. Validation of mechanical design, previously conducted by the manufacturer, was carried out according to ASME […]
Vibration Analysis on Process Units With Dynamic Equipment
Vibration Analysis on Process Units With Dynamic Equipment PROBLEM DEFINITION Industrial building structures in which dynamic process equipment is installed (Pumps, Compressors, Stirred Reactors / Tanks, Centrifugal Separators, Thin Film Evaporators, Coke Drum Towers, etc.) usually show large amplitude vibrations (even observable to the naked eye) that need to be corrected, or prevented, along design […]
Structural Analysis of Railway Rolling Stock Incorporating Suspension System
Structural Analysis of Railway Rolling Stock Incorporating Suspension System Advantages of incorporating the suspension system to finite element analysis CADE normally uses the Finite Element Method (FEM) to undertake simulation modelling and analysis of complex structural elements. This method is often used to analyse critical elements and mechanical parts, whose performance may be conditioned by […]
Stress Intensity Factor (SIF) For Special Geometries in Piping Stress Analyisis
Stress Intensity Factor (SIF) For Special Geometries in Piping Stress Analyisis SIF according to ASME B31J for special geometries not covered in ASME B31.1 and ASME B31.3 codes PROBLEM DEFINITION Piping Design is a critical component of engineering projects and process plants. In order to get safety pipe systems, the flexibility analysis (stress analysis) is […]
ROOT CAUSE ANALYSIS AND CORRECTIVE MEASURES OF DISSIMILAR WELD JOINT FAILURE IN A HIGH PRESSURE STEAM PIPE
Root Cause Analysis And Corrective Measures Of Dissimilar Weld Joint Failure In A High Pressure Steam Pipe PROBLEM DEFINITION During the operation of a petrochemical plant (located in Middle East), recurring appearance of cracks in dissimilar metal welding joint of a critic, high pressure steam pipe has been detected (2010-2014). Cracks appear periodically over the […]
