Introduction to ASME B31.3 Course

Hello and welcome to introduction of Process Piping Code ASME B31.3
This is ali Nouri and I hope you are doing well.
You know, at the first step of a project including pressure piping, governing Code will be specified by owner and then, this code plays the major role for establishing rules of project.
So what does the code provide us to handle the project from A to Z?
To answer this question, first, we should talk about philosophy behind ASME Code and then review history caused divisions of B31. In this course it will be discussed why we trust in code requirements instead of considering our own safety factors based on our engineering knowledge.
Actually, The Code specifies engineering requirements considered necessary for safe design and construction of pressure piping, and in this course I am going to explain how “safety factors” implemented in Code and how different codes used different methods for considering adequate safety for our project due to its scope of work.
The safety and reliability level of each project vary from another. You can imagine that the pipeline which transfers natural gas shall be protected more than a pipeline transfers crude oil. Because any failure in gas pipeline may lead to terrible explosion and many casualties while it may cause local burning in crude oil pipeline. Therefore, the safety and reliability of gas pipeline is more than liquid hydrocarbon pipeline designed & constructed based on B31.8 and B31.4 respectively. However, many engineers who use those Codes don’t know how safety factor implemented in formula in different codes that make one of them more safe and reliable than other.
The objective of this course is To illustrate how safety factors implemented in divisions of ASME B31 that makes one of them more reliable & safer than another based on scope of project

Code specifies pressure design of piping components and this course covers step by step wall thickness calculation of pipe based on B31.3. Furthermore, you will be familiar with other methods used for wall thickness calculation in another codes such as B31.1, B31.4 and B31.8 and through this comparison it will be revealed that how different methods used for safety consideration. In addition, you learn how to specify thickness and rating of fittings.
You must probably are familiar with the concept of the rating / class of pipeline such as 150#, 300#, 600#, 900#, 1500# and 2500#
Do you know what does it mean?
What Do you know about the concept of rating or class of flange?
In ASME B31.3 course, I will show you how to determine the rating of flange step by step using ASME B16.5 and you will find what level of pressure will be sustained by specific rating of flange
at each temperature.
and this concept will be discussed in this course
Based on definition presented by code, each component has its own design pressure and temperature led to higher rating or wall thickness that may vary from other components’ design pressure and design temperature. You may be surprised that under conditions specified by Code, operating pressure could surpass design pressure and I completely explain how it could be possible.
***
There is a clear boundary between Code and standard. However, I have seen engineers who say standard B31.3! In this course you will learn you how to use Code & standard and specify related standard for each piping components referring to code.
In addition to Code and standard, we use another type of documents in project named specification. For example, specification for piping material, specification for hydrostatic test pressure, specification for paint, PWHT, NDT and extra. Those specs specialized for specific project with unique site conditions such as high and low temperate, humidity and wind velocity, but principles shall be in accordance with governing code and specs might be rigorous in due to aspects of project. During course you will find the Code reference for project requirements for PWHT, NDT extent, preheating and the amount of pressure testing. You will acquire ability to use PMS (Piping Material Specification) perfectly that so valuable to handle piping work from design to construction and commissioning.
***
Code in not design Handbook and I help you to enhance your ability to use Code gradually during this course. There are ambiguities using Code without any guild and it will be my duty to remove them by this course.

hi Ali

[@mukhlismirghani-ce9fv]

Nice Job 👍when this course will take place? And how many sessions, can't wait to attend

[@naren058]

Waiting pls do 31.8 also

[@India-pp5iw]

Can you provide me the material
