DESIGN AND ANALYSIS OF A FLEXIBLE PIPE CONNECTION ON CREEP RANGE
Objective An equipment manufacturer required CADE to conduct the validation design of a flexible pipe connection, between a reactor and a steam generator, to meet the requirements of the end user. This connection had to join the output of two pieces of equipment working at high temperatures and consider the displacement of one of the […]
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 […]
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 […]
