Bangdong  can often provide the items listed below for a same-day delivery.  Large quantities, custom sizes, may be subject to a longer lead time for delivery.

Since Steel Nipple are manufactured by cutting a specified length of pipe and applying the desired end connections, the dimensions and material follow from pipe specifications.  .  Similar to pipe, however, pipe nipples may come in either a seamless or welded construction.

For swages, like reducing pipe nipples, they come in two types: concentric and eccentric.  These are shown below.  Also, rather than being manufactured to pipe material specifications, carbon steel swages come in A234, and they are always seamless in construction.  Lastly, please note that since each end of a swage is of a different size, the wall thickness (schedule) of each side can also be different.

Concentric	Eccentric

The end connections need to be specified by the customer as well; plain both ends (PBE), threaded both ends (TBE), beveled ends (BBE), threaded one end (TOE), beveled one end (BOE), plain one end (POE) or a combination thereof, depending on the ends of the piping system into which the pipe nipple will be fitted.

A PBE pipe nipple (plain both ends), has two plain ends, with no thread, typically used to fit a socket weld connection.

A TBE pipe nipple (thread both ends) has two threaded ends, used to fit female threaded connections 

A BBE (beveled both ends) has a bevel on each side of the pipe nipple and is used for welding purposes similar to a buttweld fitting. 

When listing the end connections of a swage, unlike a pipe nipple, the order matters.  The end connection of the larger OD is listed first, and the smaller OD second.  There are several end connections/combinations available for swages: threaded both ends (TBE), threaded by plain (TXP), plain by threaded (PXT), plain both ends (PBE), beveled by threaded (BXT) or other combinations of plain, threaded, and beveled.  The end connections of the swage depends on the end connections of the piping system into which the swage will be fitted.

Note: Industry language sometimes includes specifications such as "PSE x TLE", which simply means plain short end by threaded long end; the "S" stands for short and the "L" stands for long.   

Carbon Steel Nipples and swages commonly come without a coating (also referred to as plain or black), but they can also come galvanized, which has a metallic finish.  Pipe Nipples and swages made of stainless and other materials are not typically coated.
