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.

Yep. The only thing someone has to learn is sock-in (TE), which I always used 5/8 of an inch for 1/2 - 1-1/4 pipe. For anything bigger, I’ve always used 1/4” per inch increase. But fitting thread depth with 2-3 threads added is always a nice reference.

Yes, that would work as well. The reason you would need the fitting allowance is because generally measurements are given center to center and for longer distances between fittings getting the face to face measurement might be difficult.

That’s how I measure and plumb all my runs. My question is since it’s NPT and the threads are tapered meaning they theoretically aren’t tighten/bottom out to the end of the thread engagement how much of the thread engagement from both of the fittings should I add to my face to face measurement to allow the fittings to be sufficiently tighten while maintaining the center to center of the fittings for a run I’m trying to make.

What is the cut length of the pipe? 2) A length of NPS ∅1½ inch pipe is to be cut run between two 90° degree 6.000# threaded fittings. The fittings measure 7 ft 2¼ inches center to center.

Hi Homoud: A butt weld wll have no fitting allowance so you will essentially be taking the center to center measurement of the pipe and substracting the fact to center measurement of each fitting.

Or you can just measure with a measuring tape the fitting allowance. Put a dot on the centre part and where the end of the hub is and measure it and that’s your allowance.

what if it is a cast iron pipe joint using mj clamps? would it be on e-e minus the fc?
@tradestutor11915 жыл бұрын
Hello: When dealing with cast iron the clamps themselves count for very little. Lets say you had two 90 degree cast iron elbows and you were looking to cut a piece of pipe (E-E) which would fit between the two 90's in order to get the correct centre to centre measurement. You would take the C-C measurement and minus the face to centre of one 90 degree and then the face to centre of the other 90 degree. Essentially you would be taking the centre to centre measurement and subtracting two face to centre measurements as both 90's should be the same. to account for the coupling required (one on each side) you would subtract about 1/4 inch for each one, for a total of 1/2 inch. This 1/4 inch accounts for the rubber piece within the coupling that separates the pipe from the fitting. I hope this helps.

Mr Precise Lockheed you could take your digital dial calipers and measure and mark the TE on both ends. Then it will work providing you put exactly the number of wraps of Teflon tape on both ends of the pipe and then precisely torque both joints together. I can tell by your comment you aren't that particular.

@JM-rl6bq5 жыл бұрын
Correct me if I'm wrong, but say you're going face of a fitting to center, would you have to add the TE for the "face of fitting" portion then subtract the center? So, as an example 3/4" Black Iron 90 has a TE of 1/4 and the measurement from the face of fitting to the center is 45 inches, then could you just subtract the FA (on the other 90; saying it works out to be 1 1/4) from the TE to get the E-E measurement? Thus, gives an E-E of 44 inches? Does that make sense?
@tradestutor11915 жыл бұрын
I think the face to center measurement you are referring to is different than the one I refer to in the video. When I say face to center I'm referring to the face of the fitting to the center of the fitting. It sounds like the measurement you are referring to is the face of the fitting to the center of the piping arrangement. If that is the case then a different set of calculations would be required. The numbers in your example do seem to work if I'm understanding correctly what you did.
@boby1154 жыл бұрын
If we know the thread engagement is at 7/8 " & distance between the two elbow faces is 2 ' 3/4" why don't we just add it up? (7/8" + 7/8" + 2' 3/4" (6/8")=2' 18/8" (2' 2 1/4")
