Application Of Api 653 Code To Approach Modifications On Existing Atmospheric Storage Tanks
Application Of Api 653 Code To Approach Modifications On Existing Atmospheric Storage Tanks Table of Contents API-653 Scope API 653 “Tank inspection, repair, alteration, and reconstruction” standard covers steel storage tanks built according to API 650 code and its predecessor API 12C. It provides minimum requirements for maintaining the integrity of such tanks after […]
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 […]
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 […]
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 […]
