Step-by-Step: Piping Stress Analysis with CAESAR II
Expires After: Does not Expire

This course about the step by step of performing piping stress analysis using Computer programs such as CAESAR II. At this point, you would have already known which piping system to be analysed, based on Critical Line list created by Lead Piping Stress Engineer. So, you are now having with you the calculation number, line number, and most importantly knows the starting point and end point of the calculation. Both starting and end point are treated as an Anchor point.

 

☘☘☘

 

2 major things need to be prepared and make it ready in order for you to be able to start your Piping Stress Analysis calculation with CAESAR II:
1. Stress Sketch, completed with required information.
2. CAESAR II Program, has been setup to the project requirement.

 

☘☘☘

 

Firstly, is to have a Piping Stress Analysis Isometric Stress Sketch ready fo the job, this process called as a Stress Sketch preparation which is basically making the piping isomteric ready to be input into CAESAR II. The work starts with collecting or gathering all of required data; such as pipes, fittings, valves data, equipment design data, process condition, pipe support standard, piping general arrangement drawings, civil/pipe rack drawings, and could also the piping isometric. With this information, we can start the process of making the stress sketch.

   

☘☘☘

 

Secondly, once the stress sketch ready, we need to make sure also, that CAESAR II is ready. Meaning, has been installed properly, has been setting up in accordance to the specific project requirement and ready to be used for the analysis.

 

☘☘☘

 

It is very important to note here that, at this stage, the piping stress critical line list should have been prepared and officially approved by the Project Manager, along with other related project piping standard and specification to be used for the specific project.

 

☘☘☘

 

The course will be divided into 5 lessons as detail below:

1. Preparing Stress Sketch
2. Calculate Initial Movement
3. Determining Load Cases
4. CAESAR II Input and Analysis
5. Final Report

Piping Stress Analysis for Beginner
Expires After: Does not Expire

Being able to perform Piping Stress Analysis either using Computer Program such as CAESAR II, or AUTOPIPE, or even to do some manual calculation, requires some understanding of basic knowledge in piping stress analysis such as, what is Piping Stress Analysis? Why do we need to do stress analysis? What kind of skill or knowledge that we need to know in order to be able to do such a job?

 

☘☘☘


Before we answer those questions, however, there are things that we should have known prior to that, for example, the knowledge about some basics piping stuff, such as piping material, pipe sizes and schedule, pipe fittings, and pipe support, which is given in my separate courses, with the title of Piping Engineering for Beginners. If you have not gone thru that course, or you still in doubt, my advice is to visit the course and get to know that stuff, before you proceed with this course.

 

☘☘☘


I have been thinking a lot to create this course using my real and practical experience performing Stress Analysis of piping systems for Oil and Gas Projects such as LNG Project, Gas Plant Project, Petrochemical Project, Oil Refinery Project, Geothermal Project for over 29 years of experience. I still remember the feeling when I was like thrown into the deep end of the pool at my very first job as Stress Boy: confused. I just want every new fresh Engineer can at least know where to start when given the task of piping stress analysis. In other words, can be more prepared. After this course, I will prepare the Step-By-Step gudie to do Piping Stress Analysis. Although this course mainly and especially for beginners, but this could be a kind of refreshment for the experienced guy.

 

This course will divide into nine lessons starting with the function and method of stress analysis, followed by the understanding of the internal pressure design of piping, Allowable Stress, Stress Category, Pressure and Temperature use for analysis, Initial nozzle movement, pipe loading combinations, Allowable load, and some of stress consideration need to be aware of during performing Stress Analysis.

 

☘☘☘


1. Purpose and Method of Analysis
2. Internal Pressure
3. Pipe Loading
4. Pipe Properties
5. Stress Category
6. Allowable Stress
7. Initial Movement
8. Allowable Forces and Moment
9. Property of Piping Stress

Basic of Piping Engineering
Expires After: Does not Expire

The design of a piping system has been known since centuries ago when people from China utilized bamboo as a means to bring the water from the source to watering the paddy field. History also stated that the people from Indus Valley had been using a piping system to deliver the water into the houses. Don’t forget to mention the people from Egypt who bring the water from The Nile River for irrigation purposes.

 

In modern life, piping has been used to transport water from sources to the distribution points and then eventually end up at our houses. Piping also being used to transport oil from the wells to the gathering point and then to the Refinery Plant for further processing, before sending it to the end-user. In Oil Refinery Plant or Gas Plant, for instance, piping is visible being used to transfer liquids from one equipment to another equipment at various locations. Crucially, piping also plays a major role in protecting life and property as fire protection piping networks in residential, commercial, industrial, and other buildings.


Ok. So piping is important, we know now. But what exactly piping is? What do you call as piping? More importantly, what is a piping system? Is that pipe only? or pipe with something else? We will find out soon below.

 

According to Mohinder L. Nayar in his famous Piping Handbook, Seventh Edition, we call a piping system if we have a set of pipes along with other components and accessories with the same sets of design condition and which interconnected each other. The piping system shall consist of pipes, flanges, fittings, bolting, gaskets, and other piping components, as well as pipe support. So, when the pipe joined with fittings, such as elbows, reducers, and then connected to flanges, valves, and properly supported by pipe supports, then we can call as piping.

In this course, we will learn about the piping system which normally used in Oil and Gas Industry. We basically will learn about pipe material, pipe size and schedule, pipe fittings, flanges, gasket, bolt, and nuts, and finally, we will discuss about pipe support. That’s why the course title is Basic Piping Engineering since we will be learning everything about and related to basic of piping.

 

At the end of this learning, Students would be expected to have a good understanding about the type of piping normally used in Oil and Gas Industry. Furthermore, this course will also a very good starting point before proceeding to the next course about piping stress analysis.

 

☘☘☘

 

The course has been carefully prepared in order to be easier to follow and understand and will consist of 7 (seven) lessons:

 

1. Pipe Material
2. Pipe Properties
3. Pipe Sizes and Schedules
4. Pipe Fittings
5. Pipe Flanges
6. Gasket, Bolt and Nuts
7. Standard Pipe Support
