Stress Analysis-Caesar-II


Outstanding Features

Pipe Stress Analysis is an intensive five-day course designed to give a thorough understanding of basic and advanced concepts of piping stress and flexibility analysis as per industry standards. Stress analysis is a critical component of piping design through which important parameters such as piping safety, safety of related components and connected equipment as well as piping deflection can be addressed.

Course Overview

The purpose of this course is to train engineers on stress analysis related topics. Piping system design and analysis is a major part of design engineering. Piping stress analysis is a critical aspect of piping design, and allows you to address issues related to piping safety, and connected equipment, and piping stresses. The objective of such analysis is to prevent premature failure of piping and piping components, and to ensure that the stress is kept within acceptable limits as per the code and equipment vendor standards.The program will cover concept theory, Load Case Preparation, Stress Calculations, Code Requirements, and exposure to Industry Leading Pipe Stress Analysis Software.

Target Audience

Engineers who are responsible for performing piping stress analysis and others who must have a good understanding of its requirements are invited to attend including: Piping Graduate EngineersPiping Design EngineersPiping DraftsmenPiping Layout EngineersPipe Stress and Flexibility Engineers
