Standard Discipline Designator

[kengkoykolokoy]

Good Day!

 

I would like to ask question for:

1. Is there any discipline for GAS/LPG?

2. Should i go with "X" - Other Disciplines?

3. Is the GAS/LPG discipline covered by mechanical or plumbing?

 

I hope that you will be able to help me.

 

Appreciated in advance

I do believe that there are jobs in the petroleum industry that require AutoCAD, but getting a job in that field may prove difficult. I can't say for certain. If you're into mechanical and plumbing, you can try finding a job in those fields or possibly work for an electric company. You should just go for whatever discipline you feel like you will be happiest in. There are many jobs that require a draftsman, you just have to look for them.

gas and low pressure gas are part of mechanical, since you are using pipes to transport these materials

guys thank you for the reply.

 

this is my first time drawing gas lines. i just wanted to know what kind of SHEET ID for gas. example: M-NNN, A-NNN, So for gas its like "X-NNN" ?? em i right about here?

when i look at the standard disciplines, there is no discipline for gas.

sorry i did not mentioned this before.

 

@Nardino, so it means i will be using Mechanical Disciplines?

[Nardino]

so the drawing numbers for the gas lines would be M-.....

I've been in the MEP industry for over ten years. The firm I work for does Plumbing, Fire Protection, Mechanical, and Electrical. One thing that has always bugged me is the usage of the term mechanical. In it's broadest meaning, in the MEP industry, it can cover Plumbing, Fire Protection, and HVAC but it is also interchangeable for just HVAC, ductwork and piping.

 

To answer the OP's question, GAS/LPG is usually covered by Plumbing so the designator would be "P".

The 'designation' is whatever you choose it to be. It does not have to conform to anything (except if being submitted for approval somewhere which has specific requirements).

[Nardino]

With all due respect, I disagree with RobDraw. The letter P is specifically designated for plumbing drawings. As a mechanical engineer for the last 41 years, and having started in the business as a mechanincal draftman, using pencils and T-squares, this has been the designation. P for plumbing, M for gas lines. I suggest a look at the US National cad standards might shed some light on how to name any drawings.. Regards to all..........

[RobDraw]

Disagree all you want but this is the way it is usually done here and other MEP firms and has been for more years. We are large MEP engineering consulting firm. You must consider that there are different standards out there. BTW, the US National CAD Standard is not a standard because no one follows it to the letter.

We follow the NCS to a tee - almost literally. And P = Plumbing where I'm employed. Not trying to add fuel to the fire, just stating is all. I think it has to do with larger firms like mine having committees for quality control. It's the "politics" part of a corporate environment, and national standards is always the referencing bible (NCS for CAD, ASHRAE, NEC, etc).

[Nardino]

Do as you wish. Of course as you say you are working in a very large company and this is what your company follows. So follow it. No problem.

Tanner, the key word is "almost". My point is that once you deviate from it, it no longer is a standard but a guideline.

[Nardino]

I hope there is no fire in here. Just a difference of opinion.

Well, NCS standards is only a guideline period. Ha, we try and explain this all the time to our CAD Standards Committee. Just can't get it through their stubborn heads!! lol, but they are so dead set on it that we've just given up the fight.

 

Smaller firms... hell, put it on "A-XXX" if you want. Contractor will eventually figure it out.

With all due respect, have a look in the US NCS under the P = Plumbing designation, it includes Process Piping. You are not required to use the level 2.

it seems that this is a good discussion.
