Natural gas pipe sizing

This one covers wrought iron pipe sizing for natural gas systems. This method is the branch length method (402.4.2) and conforms to the IFGC 2009 code book. The charts are the same in the 2012 code book, just different page numbers.

7yrs later and this is STILL extremely helpful and so very easy to understand. This is the best instructional video I've seen in YT thus far. It just sucks that I had to watch 8 before, finding this.

Old video...but for all of you checking this out. On table the numbers displayed is for CF/hr not BTU's... 1100 BTU equals 1 CF/hr. You must divide the 350,000 BTU's for 1100 to find the CF/hr to use the table. He missed that step and therefore had a size or two larger pipes that he needed. Good luck!

GFM you are the man ! I can get my gas masters today thanks to your help sir. I couldn't learn this by just reading the IFGC I tried . Thank you sir !

[@Gemini2Two]

Great instruction. My memory has been refreshed. You explained this better than most journeymen plumbers I have worked with. Thank you!

Just a homeowner redoing my gas pipes to accommodate adding a tankless water heater and high output gas fireplace, but found this really helpful. Oversized everything to 1" and reduced right before appliances. Gas company came out to hook up at meter and said I could have just had them bump up the pressure instead. Whatever, I sleep well at night and no more rusty 40 year old gas pipe hanging from coat hanger wire under the house and which some idiot thought needed insulated with rolled newspapers.

Fabulous! You were clear and methodical. The sites I visited prior to this didn't make sense. Now I know the sizes I need to feed my generator.

Thoroughly represented on PowerPoint and explained. Helped me comprehend and apply the 2012 IFGC methodology to calculate a rough-in we had to do on a New Orleans, multi-unit structure. Tom Jones, ColdAirNOW!. Thank you for the time take to prepare this excellent presentation.

I would stay in the 70' column/row for all pipe size calculation. End up with the same the same result. The way I was taught. Using your video to teach a few apprentices. Thank you for posting this video.

[@lonestar6821]

Very informative, nicely explained in plain simple language. Thanks 🙏

[@b_rad5678]

Best explanation / detail I've heard.

[@ralphwaters8905]

That methodology is a clever and simplified way to get a consistent pressure drop per foot of pipe throughout the system. Once you understand that, it all makes perfect sense.
