That was a great tutorial. After 60 years, I finally learned something about pipe threads.

Good tutorial !!! simple & effective. Thanks Sir.

Very Well done video, and good explanations. Thank You!!!

Excellent video considering SW does not have default NPT settings, helped a lot! Thank you.

Hi David, see this: kzread.info/dash/bejne/aYSjscirds-Ykco.html

Great job Alex MOLODETS!!!! Thank You Very Much! Alex what are the material settings you have I picked AISI 304 steel just like you have and mine looks not as attractive as yours. 304 you used for the previous video of the internal thread and here you use AISI 316 Stainless Steel Sheet (SS) and by just choosing this material nothing looks a cool as it looks on your model. Please suggest if it is all possible :)

Where did you get the value p/8 from for the width of the root? I think the h value you got should be measured from root to crest, not from base to crest. H is measured from base to peak.

Alex, very good tutorial, short and sweet. I just have a question on the root length formula of P/8 or 1/n/8 at 6:44 min, do you know which section of the standard ASME B1.20.1 it is mentioned? I can see that Section 2.3 gives you the total height of the sharp V thread, H, as 0.86602540xP and section 2.4 gives the truncated thread height h = 0.8P. Can you explain how did you derive the root length as P/8?. One more detail that I noticed is the location of the cutting tool shown at 8:13 min. I would pick the point on the triangle from the intersection between the pitch diam and the mid point of the side and snap it with the end of the piece as shown on figure 3 of the standard ASME B1.20.1 (Fig. 3 American National Standard Taper Pipe Thread Notation ).

Great catch, I reviewed ASTM F1489 and I agree with your first point. However, for the start of cutting tool, I would draw a line between the mid points of sides and apply the pitch dia to the mid point of the line, which maintain the effective thread length L2. Then snap the point to the end of the shaft.

Nice tutorials. Just watched 3 of your vids! Do you have a machinist handbook recommendation? Thanks

The BEST video to watch! Yuu can make ANY MNPT thread with this example! Should we RADIUS the end of the cutting tool?? Would be AWESOME to see making a pipe nipple that uses Mirror. I ask this because when I mirror my doggone thread on the mirrored side is BACKWARDS! I have seen many KZread Videos that do NOT make them backwards. I am using SolidWorks 2012.. Got suggestions??

Thanks, Dave, NPT thread form is not rounded. Roots and crests are flat. Of course, in SolidWorks we can round them, but it would not be NPT threads anymore. Rounded roots and crests are in BSW - British Witworth threads, where the tooth angle is also different. It's 55 degrees, as opposed to 60 degrees in NPT.

ANSI B1.20.1 shows the treads should be truncated and define the min and max of truncation. The truncation is shown as a flat (not curved) spot in the thread; however, in reality, the roots and crests get rounded as the tools wear. So, as long as the tools can maintain the min and max truncation tolerance you are good. BTW: When I was taught to cut threads on the lathe using single-point cutting (60° taper cutting tool) I was instructed to grind a flat at the apex of the 60° angle of the cutting tool to be within the "width of flat F equivalent truncation" table from the Machinery's Handbook.

Thanks

Great tutorial, just let me do u a question, may be obvious. Does this NPT Male thread fits the female one that u did in the internal NTP tutorial?

@encole7224

6 жыл бұрын

As long as it's the same size, NPT threads will fit male to female.

excellent couple of videos, however I have a doubt, in the video of male thread the profile of the thread was left in vertical orientation, that is to say parallel to the "OD of pipe .375" (min 6:30), and in the video of female thread the thread profile is aligned to the preparation of the cone (min 9:12 in the other video). Is this correct? Shouldn't they both be aligned to the cone?

@encole7224

Thank you for your comment. I real life, the thread is made by a single point cutter moving at a taper, so the line is indeed at an angle. In CAD you are correct, the root line should be at an angle because the thread is cut in one sweep feature.

Is there any way to make this a template in solidworks in the same way you can make modifications to the hole-thread wizard for custom threads so that you dont have to go through this process each time you want to add an NPT thread to something?

@encole7224

Each variable in a sketch can be assigned to a global variable such as the thread size, for example. This way, when the thread size is given a new value, say 1/2 or 1" or 1-1/4, all dimensions in every sketch will automatically change based on that global variable. This can be done using Equations.

Convert entities step is confusing. My version of Solidworks doesn't look like that. The Helix move is not immediately available after Convert Entities

I really appreciated this video. however I found one thing interesting. it seems the crest width(or thickness) varies based on the thread length. in this video, it was set at 0.7. the longer thread length, I have the thicker crest. Any one has insight for this issue that I have?

@encole7224

2 жыл бұрын

Make sure the taper angles are the same: the solid extrusion taper and also the Helix angle (in the thread) are the same. Is one angle is different, then the swept cut will create different crest width with every turn.

Hi, if will take high length of threads than it doesn't work well

Ok I know I am missing something simple, but what if you want the thread longer than .700 I would like to make it 1 inch. but when I try to do that it makes the crests of the threads fat. The .700 I am referring to is at 4:06 in your video.

Thank you for your comment. For a longer fitting, adjust the pitch diameter accordingly. It will become smaller for a longer thread.

Why do you use a .7in thread length when in the table it is defined as 1.05in (L4) in the table?

@encole7224

Shorter length is to make the part more compact. 0.7 length is sufficient for a number of full turns including a thread relief.

Yes but then the distance from the tool and the axis should be longer when posiioning the tool. The table value can only be used when the table length is used.

Hi! how did you determine the first diameter on minute .29 the one that is 2.50. Thanks

@encole7224

That 2.5" diameter is totally arbitrarily. In this video example this 2.5" is the outer diameter of the hypothetical pipe. NPT thread at the ends of a pipe are typically smaller diameter than the overall pipe. The important dimension is 2.375" diameter, which is the nominal dia. for NPT size 2". 2.5 is larger, so I chose this number as a good starting point. Makes sense?

Hola! Do you refer to taper angle? If yes, just calculate 1/16 angle (half of that per side 1/32 = 1.789 degrees) and enter it directly into your dimension.

Hi, I'd like to ask, for the atn formula, why atn(1/16)/2? Where did you get it? Or it is a fixed?

@encole7224

5 жыл бұрын

It's trigonometry determining the actual angle. The taper angle is defined by a unit of 1 length over 16 units. The angle between two lines is the arc-tangent of their lengths. Atn(1/16). Divided by 2 because 1/16 angle is for the entire cone, not just one side. It actually should be atn(1/32).

Akram, thank you for the question. In real production the tooth will be cut with a single point cutter moving at the taper angle. Thus creating the root of the tooth aligned with the taper. In CAD, yes, the sketch technically should be aligned to the taper. For a quick video it's easier to create a model with parallel sketch. Good observation.

HOW TO GET THAT EDIT EQUATION DIALOG BOX. IN MY CASE ITS NOT APPEARING

@encole7224

3 жыл бұрын

On 2016 and later SW versions double click on the dimension you want to change. It's a fast double click. This will open a little dialog window, in the same spot where the dimension is. Type the equal sign "=" into the dialog window. From there you will have options to add a Function, Measure or look up File Properties. Choose -> Function (it's a dropdown menu) and select the atn(), or whatever function you need. In SW versions earlier than 2016, double click the dimension and select the down arrow in the text field there.

Isn't your equation for the taper angle wrong? Shouldn't it be divided by 2, then ran through atan?. atn(1/32), not atn(1/16)/2.

@encole7224

You are correct, the taper angle is atn(1/32). Good catch, thank you! For practical purposes the angle tolerance will accept either equation. 1.7882 vs. 1.78991 are within manufacturing tolerance. The actual angle is acceptable for passing go-no-go gauge within 1.78 degrees +/- 0.05 degrees, the block tolerance on drawings.

You are correct. In practice, although, the difference between arctan(1/32) and arctan(1/16)/2 is 0.0017 degrees. It is well below the manufacturing tolerance, so the angle will work out in the real world. The math was an oversight in the video, thank you for pointing it out.

Great tutorial. But this is dumb. Solidworks NEEDS a NPT option in hole wizard. Its such a common engineering thread for plumbing. Smh
