Pipe ( nipples) ends

This article describes the available and different pipe end configurations, the scenarios in which they are most often used and the factors to consider when choosing a specific pipe end. The type of pipe end chosen determines how the pipe connects to other components and for which applications and components the pipe is best suited.

Most commonly used pipe ends

Pipe ends usually fall into one of the following standard three categories..

Threaded Ends (TE)
Bevelled Ends (BE)
Plain Ends (PE)

In contrast, a pipe may have a description of TBE, which means both ends are threaded.
A pipe, on the other hand, may have a description BBE, meaning that both ends are provided with bevelled ends
pipe, on the other hand, may have a description PBE, meaning that both ends are provided with plain ends


TE	BE	PE

The listed pipe ends are all standard configurations and apply to single random lengths of approximately 4.8 to 7 metres and to double random lengths of approximately 11 to 13 metres.

Shorter and longer lengths are available with several ends, but for calculation purposes it is wise to use these standard lengths; other lengths with different ends are available, but are likely to be more expensive.

Most commonly used pipe nipples ends

compared to pipe, pipe nipples are available in all kinds of standard variations.

At this point, the abbreviations of pipe and nipples should be explained. As may be noted, the abbreviations all start with the type of end T ..B.. P..., which is the only correct designation. In practice, however, other nomenclatures are often applied, and when an order is placed it may be unclear what should be delivered.

The table below shows the correct abbreviations, with the explanatory text.

TBE	Threaded Both Ends
BBE	Bevelled Both Ends
PBE	Plain Both Ends
TOE/BOE	Threaded One End Bevelled One End
TOE/POE	Threaded One End Plain One End
BOE/TOE	Bevelled One End Threaded One End
BOE/POE	Bevelled One End Plain One End
POE/TOE	Plain One End Threaded One End
POE/BOE	Plain One End Plain Bevelled One End
by the way nipple TOE/BOE is the same as nipple BOE/TOE etc.
unwanted
BET	Both Ends Threaded
OET/OEB	One End Threaded One End Bevelled
OEP/OEB	One End Plain One End Bevelled

When ordering a pipe nipple In addition to specifying the right ends, it is necessary to determine and correctly specify the diameter, wall wall thickness and material.

Most common swage nipples ends

TBE	Threaded Both Ends
BBE	Beveled Both Ends
PBE	Plain Both Ends
TLE	Threaded Large End
TSE	Threaded Small End
BLE	Beveled Large End
BSE	Beveled Small End
PLE	Plain Large End
PSE	Plain Small End

Generally, there is no problem if both ends are of the same type. However, if ends of two different types are needed, the nomenclatures must be combined correctly.

For example, ordering a swage nipple PLE/TLE would not make sense, because both refer to the large diameter end. The correct one would be PLE/TSE, which stands for a swage nipple with a large plain end and a threaded smaller end, or a similar combination, depending on the application.

Besides specifying the correct ends, it is necessary to define whether it should be a concentric or eccentric swage nipple. and to specify the diameters, wall thickness and material.correctly.
