ASME B16.11 covers ratings, dimensions, tolerances, marking and material requirements for socket-welding and threaded forged fittings.
Forged threaded elbow dimensions and weight are designed in ASME B16.11 standard, and in types of straight & reducing elbow, female/female & male / female elbow, 90 & 45 degree elbow. Their size are from 1/8″ to 4″ and afford pressure in Class 2000, 3000 & 6000.

The NPT (National Pipe Thread) thread is a tapered thread used primarily in the United States. It is used for pipe fittings, hydraulic fittings and pneumatic fittings. The NPT thread is characterized by its 60-degree tapered angle and size indicated in inches. Here is a correspondence table for NPT fittings, with male and female diameters in millimeters:
Male diameter (mm)
| TPN | Female diameter (mm) | |
|---|---|---|
| 1/8″ NPT | 9.73 mm | 9.25 mm |
| 1/4″ NPT | 13.46 mm | 12.85 mm |
| 3/8″ NPT | 17.09 mm | 16.51 mm |
| 1/2″ NPT | 21.34 mm | 20.78 mm |
| 3/4″ NPT | 26.67 mm | 26.11 mm |
| 1″ NPT | 33.25 mm | 32.69 mm |
| 1 1/4″ NPT | 41.91 mm | 41.33 mm |
| 1 1/2″ NPT | 48.26 mm | 47.63 mm |
| 2″ NPT | 60.33 mm | 59.69 mm |
| 2 1/2″ NPT | 73.02 mm | 72.39 mm |
| 3″ NPT | 85.73 mm | 85.02 mm |
| 4″ NPT | 113.27 mm | 112.52 mm |
ASME Threaded Elbow is actually a fitting that is being installed in between the two lengths of tube or a pipe to allow in changing the direction of a flow.
ASME B16.11 threaded tees are used to connect 3 pipes which meet at a point. It can also be applied to combine the flow from two inlets to one outlet or for mixing of liquids.
As one of the most common pipe fittings, usually the threaded tee is a fitting in which the side inlet pipe enters at a 90-degree angle, or an angle other than 90 degrees.
