  • This Module introduces various aspects of Pipeline Stress Analysis, starting with a comparison of Piping and Pipeline which highlights the main differences. The approach towards Pipeline Stress Analysis is different and must be well understood.
  • Pipelines and their failures
  • Difference between Piping and Pipeline stress analysis
  • Pipeline fittings
  • Introduction of Pipe-Soil interaction
  • Restrained and Unrestrained sections
  • Water hammer effects on Pipeline
  • Introduction to Seismic wave propagation
  • Pipeline buckling, soil liquefaction, etc.

  • This Course is useful for all engineers who wish to make their basics clear in Pipe stress analysis. If you wish to "Experience" the "Stress Concept" and not only understand it mathematically or in bookish language, and most importantly if you possess patience and passion for the subject, then this Course is for you. This Course is divided into 3 videos. In these Courses we will discuss:
  • The concepts of Displacement Field, Stress & Strain Field
  • Modulus of Elasticity and its significance
  • What is 'Tensor'? Stress as a Tensor
  • Longitudinal stress, Radial stress, circumferential (Hoop) stress
  • Moment of Inertia
  • Stress-strain curve and practical approach

  • This Course is continuation of Course-1 and hence applicable for all Mechanical and Production engineers irrespective of their experience. This Course is highly recommended for undergraduates, fresh graduates, piping engineers, site engineers, and stress engineers. We go a little deeper into concepts like:
  • 3D state of stress
  • Mohr's circle
  • Theories of Failures
  • Maximum Shear Stress Theory
  • Von Mises theory
  • Importance of stress analysis
  • Also, a simple problem is solved by hand calculations to calculate the stresses in the system. The intention of this Course is to make the participant look at the problem without taking help of software.

  • A highly recommended Course for all stress and piping engineers. There are various codes based on their applications. For example, ASME B31.1 is for Power Piping, B31.3 is for Process Piping, B31.4 is for Liquid Hydrocarbon transportation etc. It is like "learning languages very close to each other". If you know one language and its grammar well, then it is simple to grasp other languages. Unfortunately, most Piping engineers do not read the code carefully. Some read the code but cannot interpret it. The equations provided in the codes are followed as is. However, all these equations are closely related to basic stress concepts and engineering theories learned in schools and universities. If an engineer understands why code equations are written in a particular way, they can relate them to new challenging problems and understand the code clearly.
  • Primary stresses and their characteristics
  • Secondary stresses and their characteristics
  • Occasional stresses and their characteristics
  • Which type of stress is more critical
  • Mode of failure of each type

  • This Course is continuation of previous Course and hence must be heard after completing Course 3. This talks about the code equations in detail.
  • Why equations are written in a particular way
  • What is the significance of + and - sign?
  • What is 'stress range'?
  • Stress relaxation
  • Self-springing of material
  • What are liberal stresses
  • Scope and Exclusions of ASME B31.3
  • Primary stresses equation and its allowable
  • Secondary stresses equation and its allowable
  • Occasional stress equation and its allowable

  • Defining the load cases is very important in pipe stress analysis as it is a relation between the software and the code requirements. Defining right load cases and understanding the mathematics behind the load cases is very essential. Most of the time it has been observed that engineers copy the load cases or try to learn them by heart.
  • How to write load cases and their nomenclature
  • There are various methods of combination such as scalar algebraic
  • Also, it answers critical questions like 'why a particular load case is written in a particular way?'
  • How to write the load cases using CAESAR II software
  • Different types of load cases
  • How allowable stresses are understood by the software when calling a particular load case by name
  • How to write load cases when a spring is introduced in the system
  • How to write load cases when a force is present in the system
  • This model also relates the load cases with the code equations. This Course is extremely useful for engineers with less than 5 years of experience who wish to understand the mathematics and the 'Why' behind the load cases.

  • Today's world is software driven. Engineers are no exception. Engineers often cannot give solutions without using software, so knowing the advantages and limitations of the tool is essential. CAESAR II is one of the finest stress analysis software using beam elements.
  • Basic elements
  • Hand calculation of thermal force and stresses, evaluating them with scissor to answer
  • How software works
  • Important features of configuration setup
  • What is 'degree of freedom'
  • Introduction to modelling commands
  • Node and connecting Node, its application
  • How to apply wind and earthquake loads
  • Advantages and limitations of the software
  • Difference between pipe element and rigid element

  • This module explains in detail how to read pipeline-related documents and interpret them to create the CAESAR II model quickly.
  • Key points in Pipeline Design Basis
  • Alignment sheets
  • Pipeline P & ID
  • Station Approach Drawing
  • Monolithic Insulation Joint

  • This module is a continuation of the previous module where we learn how to create a CAESAR II model accurately and quickly. It is presented as a case study showing the pipeline model along with launcher, receiver, and MIJ using CAESAR II software.

  • After completing MODULE 1 to 9 successfully, engineers should start experimenting, modifying models, and observing results. At the initial stage, 'trial and error' is effective for learning stress analysis. Engineers should predict results of small models and verify them with CAESAR II. This MODULE is designed for beginners in the software.

  • Stress engineers often lack knowledge of soil properties, which is essential for buried pipeline analysis. The buried module in software is usually known only for 'Data Entry'.
  • Overview of buried pipe behavior
  • Soil properties and their significance
  • CAESAR II buried module – Basic method and ALA method
  • Comparison between above two methods
  • Discussion on technical paper

  • Engineers should first conceptualize a solution mentally, model it accurately in software, and then compare results. This module teaches traditional methods of pipeline stress analysis before sophisticated software existed.
