A beginner !! Help needed!!

Hi Jaglan,

The training section on the site is a good place to start, read through everything (maybe print out the sections, so you can make notes on them). You may not understand everything at first, but it should give you a broad overview of what is required.
Come back to the forum and ask specific questions on specific topics, there are many people on this forum willing to help.

Books - we have a listing of book available on Amazon, pipingdesigners.com/contents/piping-books.html

This list is by no means complete and will be updated from time to time, so keep an eye on it.

Also is it possible for me to shift my career from construction line to design & would I need a post graduation for it ?

Yes, anything is possible!
A post grad is NOT an absolute requirement, but this may depend on the the requirements of any prospective employer.
To get started in piping design, you will need to find a company willing to employ and train you, as this would be a trainee/junior position, do not expect big wages!
Most companies will start you off as a drafter, doing P&IDS, PFDs and what ever work nobody else wants to do ... this is all part of the learning curve - embrace it, go with the flow, ask lots of questions and try to identify a senior designer within the company that would be willing to act as your mentor. A good mentor is key.

Before starting in a junior position, most companies will expect that you have CAD abilities, be sure that you have some training in the basics - 2D & 3D Autocad ... although you probably wouldn't expect to do any 3D work for a long time.

You will hear people telling you to learn PDMS / SmartPlant / Cadworx etc, etc ... don't worry about it ... learn what PFD's & P&ID's are first, learn how they relate to equipment layouts, how they relate to line lists, learn why layouts are laid out like they are, learn to draw, to sketch (field sketching is a valuable skill), learn to take surveys ... the list is long, and that's before you can even start designing piping systems.

Also look at online courses, such as SPED - www.iniped.com both of these offer online training and certification.

What I mention above is just for starters ... there is a lot to learn, but don't let that discourage you, I mention all this, so you are going in with your eyes open.

This is a long road ... but is ultimately, a rewarding career.

One last thing, do you know any piping designers?
Try to get to know on on your site, or in your area ... by him/her a coffee and talk about your goals - they may be able to give you valuable information as to how things are done in your country.

Jaglan,

"I am reading p&id's everyday but don't know how to relate them to plant layout and skimming the contents of Piping Handbook (McGraw-Hill Handbooks) by Mohinder L. Nayyar. I hope I am on the right track."
I would like to offer the following comments and I hope I can help you.
1. There is very little direct relationship between a P&ID and the actual plant layout. With experience a good plant layout designer can look at and "read" the P&ID. Then using prior knowledge of the rules of equipment relationships and equipment spacing he or she will be able to start arranging the equipment to form a preliminary Plot Plan. this will then be followed by some trial and error adjustment when the high value lines (Very large, Alloy, very high pressure, high temperature, sloping or gravity lines, etc) are plotted onto the preliminary plot plan. You will then adjust the equipment as required then re-plot the key lines. Do this until you get it right.
2. The "Piping Handbook (McGraw-Hill Handbooks) by Mohinder L. Nayyar." is not a good text book for learning what you say you want to do.

Good Luck,
James O. Pennock
