ASME B16.11 Threaded Pipe Fittings Stainless Steel Pipe Nipple

Threaded pipe fittings provide permanent welded connections for pipes. Threaded joints probably represent the oldest method of joining piping systems. Same as Socket Weld fittings, threaded fittings are mainly used for small pipe diameters (Small Bore Piping); generally, for piping whose nominal diameter is NPS 2 or smaller.
They are available in three pressure ratings: 2000lbs, 3000lbs and 6000lbs.

ASME B16.11 is the standard contains ratings, dimensions, tolerances, marking and material requirements for forged fittings, both socket-welding and threaded. ASME B16.11 Threaded Pipe Fittings are available in pressure ratings Class 2000, 3000, and 6000;
Socket welding fittings are available in pressure ratings Class 3000, 6000, and 9000.
Generally, both fittings size range is 1/8″- 4″or DN6-DN100.
There are various types of ASME B16.11 socket-welding fittings, such as Elbow, Cross, Tee, Coupling, Half Coupling, Boss, Cap, Union and Sockolet; while ASME B16.11 threaded fittings can be furnished in product forms of Elbow, Cross, Tee, Coupling, Half Coupling, Boss, Cap, plug and bushing.

Threaded nipple is a short piece length of pipe or tube. Its size is specified according to the length of this section of pipe and the diameter. It can be with threaded or flat ends. And both ends can be the same or different.

 

There are two shape : threaded one end (TOE) and threaded both end ( TBE).

Specifically, TOE means threaded at one end when translated. Thus, we can say that a nipple TOE is a nipple that has one threaded end.

In this case, we have the acronym TBE for “threaded both ends” which means threaded at both ends. In other words, this is the most typical type of nipple as described above for connecting two parts or fittings with female threading.
