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 they have placed in service and addresses inspection, repair, alteration, relocation, and reconstruction. API-653 […]
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 […]
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 […]
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 […]
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 […]
