Course Description

In this course, you are going to learn How to Read P&ID (Piping and Instrumentation Diagram), Block Flow Diagram (BFD), and Process Flow Diagram (PFD). If you want to learn to read Process Flow schemes (PFS) and Process Engineering Flow schemes (PEFS), this course is for you, also.

Read, Interpret and understand P&ID like Professional Engineer.

  • Understand the drawing’s components

  • What are P&ID, PFD, and BFD, and Why is it used? What information do these drawings provide?

  • Learn P&ID and PFD Symbols

  • Read Tank farm and Process Plant P&ID and PFD

  • Read P&ID for Column, Heat Exchanger, Pump, Tank, etc.   

Learn to Read P&ID, PFD, and BFD by Using Industry Standard Drawings with real-life examples.

There is hardly any course available that teaches how to read P&ID in-depth, and without the help of a good mentor, it is challenging to learn and understand these drawings.

If you are working in Oil and Gas or any similar Process industries, you know the importance of reading P&ID and PFD. In this course, you will learn to read from real-life drawings so that there will be no disconnect between what you will learn and what you will see while on the job.

What are you going to learn in 39 lectures? 

This course has more than 3 Hours of high-quality video content. The course is designed in such a way that even if you don’t have any previous experience, you will still be able to master each topic covered.

The course starts with essential parts of the drawing specially designed for those starting afresh.

Reading P&ID and PFD is nothing but understanding the symbols on the drawing. Before moving to the actual drawing, you will learn the P&ID symbols that are used in these drawings.

P&ID and PFD, selected as examples, cover all major components of process facilities, such as refineries, power plants, petrochemical complexes, and offshore oil platforms.

You can test your knowledge using a quiz designed based on the fresh P&ID that is not used in an example.

When you finish the course, you can confidently read and understand any P&ID, PFD, and BFD that you will encounter at work.

I know we are all short of time, so I have covered only the most valuable information in this course and tried my best to keep this course short.

So, you have more time to enjoy the things you like most.

This course was thorough and structured. The symbols of equipment and their uses were explained clearly and why something is given at certain part in P&ID it was explained clearly. It will really help me in my project work of reviewing and working with PFD & P&ID.

By Derek Byrne on 7/29/2026

I wish I found this course sooner, it is very clear for a Project Contols non-engineer to understand. I learned something withing this first 5 minutes. Very excited to take this class.

By Gary Futral on 4/12/2026

It's a great match! I like the differentiation of the spare called out as a steam turbine pump. Minimized/simplified instrument controls is good. There seems to always be a discussion as to how far to go with the intrumentation controls on PFDs. Some people don't want any. Not sure why.

This course “How to Read P&ID, PFD & BFD used in Process Plant like Pro” is very well structured and easy to understand. The instructor explains concepts clearly, starting from basics and gradually moving to practical understanding, which is extremely helpful for beginners as well as working professionals.

Explicado muy bien. Solo podría dar una observación y sería colocar otro ejemplo completo "en un video, a nivel de refuerzo" donde se explique una planta cualquiera para reforzar lo aprendido.

By Mustafa Shareef on 12/5/2022

The course is very good and gives you a lot of information mainly for all levels. The explanation is perfect and well-structured. One point: don't depend on the sections in the course, they are not arranged as per the introduction.

By Jorrick van Pol on 9/2/2022

Het voldeed aan mijn verwachtingen, echter is de uitspraak van sommige woorden verwarrend. "Valve" wordt uitgesproken als "Wall". Maar dit is niet te overkomen door het accent van de tutor.

By Ivy Joy Ferolino on 5/16/2021

I'm a beginner in this field and this is very helpful. It is very detailed and informative. My only concern is that I could not understand some words because of the pronunciation. But overall, I am very satisfied with this lecture. Thank you very much! Keep it up! :)

By Mohammed Azhar Gundu on 11/23/2020

The course covers all the aspects related to PFD, P&ID drawings with simple explanation and easy to understand technique. It was definitely very helpful for me in my career.

By Mohammed Shabbir Hussain on 11/3/2020

Mr. Varun had delivered in smooth manner, It was very well explained.
I recommend to every fresher & non-technical person to take up this course.

By Dave Meet on 10/27/2020

Nice content with full of practical information.

By Lance Kaneoka on 10/20/2020

A lot of sections could be combined. I think that ID tags should have be covered more with examples set up and explained. but other than that I found it to be helpful.
