Fitting allowance for the piping trades

This video goes through an example of how to calculate the end to end measurement of a pipe given the center to center measurement and using fitting allowance as a guide.

Mr T, thank you and God bless you for simplifying these vital calculations. This will be a breeze transfering to PVC piping!

I’ve been working with pipes for years and well. This was great I never knew it before but you learn something new every day… Great showman… Keep on rocking.

Great video. I'm a third year. I was trying to explain this to a first year who thought the thread engagement was the FA. I used to think the same exact thing when I first started out. This illustrates the differences perfectly. Thank you!

Seriously. One of the most helpful videos on YouTube! Thank you 🙏

Thank you for making this video the guy who taught me didn’t really explain the actual equation needed to find it

[Chrominance]

This was a better explanation than the one on my schools website. Well done.

Great video I’m an apprentice and was having a hard time with this while working with copper but this makes a lot of sense

As someone starting their own side business in the trades I greatly appreciate you for these videos!

I'm going to write down the link for the salesman at Lowe's plumbing department. He explained the principles but wasn't aware of formula and standards table. Awesome video. My trellis frame for vertical vegetable gardening constructed of 1/2 inch galvanized steel is well on its way to completion! Thank you.

AHHH dang This made me understand fitting allowance much better!

All those fractions in the calculations are a perfect example of why metric is easier and simpler.

Wish I could like this video a thousand times

Ur videos are so helpful.. keep on uploading plz

The east side of the pipe (FA), at 3:16 the inside line is touching the fitting, the west side is different. Is that critical?

Hello, excellent explanation for the measures required in threaded pipe installation. My query has to do with the fitting as such, that is, from where they obtain the dimensions of each threaded accessory, depending on whether it is, ANSI # 150 or ANSI # 300, or 2000 #, 3000 # or 6000 #, according to the Manufacturers' catalogs can vary from one to the other, I tried to take the data and dimensions of ASME B1.20.1 but the FC and TE of each fitting differ with the manufacturer's catalogs even with the example in the video.

For the example in the video that is a FC = 2 "and a TE = ⅞", if I'm wrong please correct me, according to the tables I got corresponds to a fitting, 90 degree elbow of the threaded type NPT 3000 # and it would be to couple a pipe of nominal diameter or size NPS = 1¼ ", FC = 2" but TE = ¹¹⁄₁₆ and in other cases TE = ⅝ ".
I appreciate the clarification and, if possible, provide the source table of the information with the dimensions of the fittings.

So how do we find the measurements for the thread engagement, you sort of just said we will just say it's 7/8" but how do I know what the thread engagement is on a T or a union?

[vkarabin]

Question.. how to remove pipe between two fittings without having to remove more then what’s necessary?.. thanks

[Renefuentes]

Thank you very much! Very informative!

[Ommarrie]

Can you do a video on calculating end to end measurement with a union?

[atgimm]

Thank you so so so so so much. My teacher couldn't even teach this !
