  • 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 wish to understand it mathematically or in bookish language and the most importantly if you possess patience and passion for the subject then this Course is for you. This Course is divided in 3 nos. of videos. In these Courses we will discuss
  • The concepts of Displacement Filed, Stress & Strain Field,
  • Modulus of Elasticity and its significances
  • what is 'Tensor'? stress as a Tensor
  • Longitudinal stress, Radial stress, circumferential (Hoop) stress
  • Moment of Inertia
  • stress stain curve and practical approach to look towards it.

  • This Course is continuation of Course-1 and hence applicable for all Mechanical, production engineers irrespective of their experience. This Course is extremely recommended for the under graduates, fresh graduates, piping engineers, engineers working at site and stress engineers. We go 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 to 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 of the Piping engineers do not read the code carefully, some of them "Read" the code but cannot "interpret" it. The equations provided in the codes are followed as it is. However, all these equations are closely related to basic stress concepts and engineering theories which we learn in schools, universities and if an engineer understands "Why" behind the code equations, are written in a particular way then he/she gets an ability to relate them with new challenging problems. Also, it makes the understanding of code clear.
  • 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 do copy the load cases or try to learn them by heart.
  • This Course talks about
  • how to write load cases their nomenclature
  • there are various methods of combination such as scalar algebraic.
  • Also, it tells about the answers of many critical questions like 'why a particular load case is written in a particular way'?
  • how to write the load cases using Caesar II software
  • What are the different types of load cases?
  • How the allowable stresses are understood by the software when you call a particular load case by a particular name
  • How to write the load cases when a spring is introduced in the system.
  • How to write load cases when force present in the system.
  • This model also relates the load cases with the code equations. This Course is extremely useful to the engineers with experience less than 5 years for those who wish to understand the mathematics and 'Why' behind the load cases.

  • Today's world is software driven. Engineers are no exception to it. It has been observed that engineers cannot give the solution without having software with them. Then it becomes essential to know the advantages and the limitations of the tool we are using. Hence knowing the stress analysis software and its advantages/limitations, the way it has been programmed etc. is very important. CAESAR II is one of the finest stress analysis software using beam element.
  • In this Course we will learn
  • basic elements true

  • difference in pipe element and rigid element

  • Course number 7 is continuation of Course number 5. In Course number 5 we had learnt the theory about the load cases, how to write them, and its combination methods. In this Course we are going to learn how to build the load cases in CAESAR II software.
  • What are the different features of this wizard?
  • How to make the most out of the various advantages provided by the software
  • How to apply wind, earthquake, forces in the load cases

  • After completing Course number 1 to 7 successfully, we have reached a stage where we should start doing experiments. For a stress engineer, it is essential to keep trying, doing experiments, making changes to the model, and observing results. At the initial stage, this 'trial and error' method is very effective to learn stress analysis. Engineers should start predicting the results of small models and verify them with CAESAR II software. The answers we get teach us a lot. This Course is designed keeping in mind that the listener is new to the software.
  • study the effects of temperature, supports and layout on the results
  • how to reduce the forces and moments
  • basic techniques how to solve a stress system, comparing the results
  • Learn few handy commands like Copy, duplicate and rotate
  • liberal stress and its effect on allowable stress

  • Our trainer strongly believes that when any stress analysis problem comes up, the solution should first be formed in your mind. Then one should model it accurately into the software and compare results. If results match your predictions, you are on the right track; if not, adjust your understanding based on the software output. In this journey, it is important to understand how previous generations performed analysis without sophisticated software. In this Course, we will learn how to calculate SPAN of a pipe based on 'allowable stress', 'allowable deflection', and natural frequency. Further, we will learn the Guided Cantilever Method, which was used to determine the minimum required flexibility in piping systems before software existed. Charts and graphs were developed based on this method. We will understand the theory, solve a problem using hand calculations, verify the same problem using Caesar II software, and compare results to learn the accuracy and limitations of the method.

  • Front End Engineering and Design (FEED) stage or initial stage of detailed piping design involves providing 'pipe rack design' even before isometric or 3D models are available. A stress engineer is often asked to determine the number of expansion loops needed for adequate flexibility. Modelling pipe rack piping in stress analysis software at this stage can be difficult.
  • to predict the number of loops on a line
  • calculated the forces and moments on the anchor base using graphical methods and evaluated them using software results
  • what should be the distance between the two anchor points on the pipe rack
  • what should be the height of the loop
  • what about the sizing a 3D loop (three-dimensional loop)?
  • This Course demonstrates solving an expansion loop sizing problem using nomographs and validates it against the CAESAR II expansion loop sizing Wizard. It highlights the advantages, limitations, and practical applicability of the graphical method. Extremely useful for piping design engineers, piping designers, project managers, and stress engineers.

  • The final outcome of extensive stress analysis is the 'IFC isometric' (Issued for Construction). These isometrics show the final pipe route and types of supports approved and recommended by the stress engineer. Supports include rest supports, guide supports, limit stops, springs, snubbers, and struts. Each support has unique features, so understanding the stress software's language and converting it into appropriate physical supports is essential.

  • Few piping engineers and stress engineers think springs in the piping system are only to absorb pipe expansion. Actually, spring hangers mainly support the dead weight of the pipe and allow free expansion. Engineers may know where to use springs by experience but often struggle to select the correct spring from software or vendor catalogue. Decisions like using spare springs require understanding of variable spring concepts, hot load, and cold load.
