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.
Pipeline Thickness Calculations as per ASME B31.4
Pipeline Thickness Calculations as per ASME B31.8
Pipeline thickness calculations for External Pressure
Buoyancy calculations
Anchor Force Calculations
Virtual anchor length calculation
Support Span Calculations

Stress Intensification Factor (SIF) is a complex and often least understood topic in pipe stress analysis. This course shares the key concepts and research insights.
What is flexibility factor
What is SIF
How to calculate it using appendix D of ASME B31.3
The limitations of ASME B31.3 appendix D
Markl's work in SIF
Overview of Finite Analysis method to get SIF
The myths and truths about SIF
How SIF is used in stress equations
Should we consider SIF in Sustained and occasional cases?
Mitre bends and its SIF
How flexibility of the bend changes with its connection to flanges
Discussing technical paper authored by the faculty

Flange leakage is a critical safety aspect. Though a complete guarantee is impossible, industry-approved practices help minimize leakage.
Pressure equivalent method and manual calculations
NC 3658 method manual calculations
Verifying CAESAR II results against hand calculations
Understanding the basics of why flange leaks occur and the required loop height
ASME Section VIII method input in CAESAR II
ASME Section VIII method manual calculations
Reference documents from flange leakage analysis
Supporting measures to avoid flange leakage

Mechanical engineering curriculum rarely covers earthquake or seismic events. When pipelines cross seismic zones, strain-based analysis due to seismic wave propagation is required.
Limitations of software to perform seismic analysis for buried pipeline
Basics about earthquake
Types of seismic waves
Boundary separation of tectonic plates
Fault types
Seismic wave propagation calculations

In addition to manual calculations, pipeline engineers perform advanced calculations due to limitations of beam element software and to avoid expensive FEA methods.
Pipeline penetration resistance calculations
Upheaval buckling calculations
Crossing (Road / Rail) calculations

A good pipeline engineer must be aware of potential hazards along the pipeline's route. While geo-specialists usually handle these, understanding them is important.
What is Geo-Hazard
Landslides
Soil Liquefaction
Lateral Spread
Fault / Fissures
Blasting
Water Hammer
Karst, Sink Holes
