Step-by-Step: Piping Stress Analysis with CAESAR II
Expires After: 1 year

This course about the step need to be taken before starting the Piping Stress Analysis using Computer, for any pping system that need to do fomral analysis. I gather this step-by-step based on more of 28 years of my experience performing Piping Stress Analysis using CAESAR II and AUTOPIPE.

 

We will start with Stress Sketch preparation, in Lesson-1, which is basically collecting or gathering all of data required to do Piping Stress Analysis such as pipe datas, equipment datas, design data, and piping general arrangement drawings. Then, we can calculate the initial nozzle movement for lines connected to equipment as well as pipe support settlement or also anchor movement, in Lesson-2.

 

Once the datas all above are ready, then we can start to make a Piping Stress sketch where we will mark nodes point and pipe support type at every possible location in the piping system as well as all of necessary information which will be needed when inputting into CAESAR II or AUTOPIPER Computer program. This is part of Lesson: 3:.

 

At this stage, our Sress Sketch is completed and ready for the stress guy to input into the CAESAR II or AUTOPIPE. However, before he start, we need to decide what LOAD CASE needed for analysis. In this Lesson-4 we will show the LOAD CASES for CAESAR II Program. Then the process of Input Data into CAESAR II program or AUOTPIPE can commence.

 

After completed the input, we start the analysis by hitting the RUN button, followed by reviewing the OUTPUT. I this Lesson-5: Quality Check we will be doing quality check of the INPUT and OUTPUT. Once quality check completed, the result can be validated and all of necessary information will be recorded and sent to respective and related discipline as required.

 

Finally, in Lesson-6, there will be some sample of load cases as well as sample configuration for system connected to equipment such as pumps, pressure vessel, and compressors. This lesson wil conclude our course in step by step and should provide you with quite information of what to do when starting the piping stress analysis job for first time.

Piping Stress Analysis for Beginners
Expires After: 1 year

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, stress criticality, how to make a critical line list chart, understanding about the type of stress category as well as Allowable Stress, 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.

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 others component 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 a pipe support. So, when the pipe joined with fittings, such as elbows, reducer, 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 Introduction to Piping Engineering since we will be learning everything about and related to 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 and pipe support.

 

☘☘☘


 

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 to Pipe Support
