Structural Integrity Assessment During Local PWHT
Structural Integrity Assessment During Local PWHT Post weld heat treatment (PWHT) is a thermal treatment usually performed in steels that have been welded. Its object is to ensure that the welding properties are suitable for its expected operation according to the mechanical and structural requirements prescribed in the corresponding design codes. This kind of treatment is usually performed on pressure equipment and pipes within refineries, petrochemical and power plants. Depending on used material and thickness of […]
3D Point Cloud Generation to Modify Existing Systems
3D POINT CLOUD GENERATION TO MODIFY EXISTING SYSTEMS OBJECTIVE In projects for the modification or upgrading of existing industrial facilities, CADE regularly performs 3D laser scans in plants, in order to obtain precise and reliable data to generate 3D point clouds. In previous years, it was necessary to start from customer-supplied models or manual data […]
Piping Stress Analysis and Finite Element Analysis (FEA) For Creep Effect Evaluation
PIPING STRESS ANALYSIS AND FINITE ELEMENT ANALYSIS (FEA) FOR CREEP ASSESSMENT The owner of a steel plant in DURGAPUR (India) requested CADE to assess the remaining life and mechanical integrity of eight gas piping systems in a power generation cycle (60MVW), including the evaluation of hanger/support points and equipment terminal connections as well. For this […]
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 […]
