Swage Nipple
ASTM A105 Swage Nipple is a type of carbon Steel Pipe Fittings and commonly used for connection two pipes with different diameters. It belongs to pipe reducers and are used in small pipe size more often.
It has two types: Concentric Swage Nipple and Eccentric Swage Nipple.
Like Pipe Reducer, Concentric swage nipple is symmetrical, both ends are aligned along the center, used in vertical pipes, Eccentric swage nipple is not symmetrical, ends are off center of one another and used in horizontal pipes.


ASTM A105 Swage Nipple Dimensions
Diameter: DN8-300/ NPS 1/4-12
Schedule: SCH10, SCH20, SCH30, STD, SCH40,SCH60,XS, SCH80,SCH100, SCH120, SCH140, SCH160, XXS.
Type: SMLS, BW, Swage. SW, Threaded.
Compared to Butt weld pipe reducer, it has small dimension range and large end connection types.

What is ASTM A105
A105 is a kind of carbon steel and common in forged steel fittings. This kind of nipple can withstand high temperatures and pressure, high strength and ductile.
ASTM A105 Swage Nipple are made with high quality material and latest technology to achieve its best performance to achieve its best performance. Compared to A105, A105N has better steel toughness and lower cracking tendency after normalizing.
To prolong its service life, customers prefer to coat them with zinc. Galvanized Swage Nipple not only has comparable service life with stainless steel, but also has good appearance and competitive price. And it is more than enough for ordinary needs. Anti rust oil is in our service as well.

Pipe Nipple End Types
ASTM A105 Swage Nipple are available with various ends, and two ends of it can be the same or different based on the requirements of sites or designs.
The end connection types and abbreviations are listed below:

- P.B.E stands for “Plain Both Ends”.
- P.L.E stands for “Plain Large End”.
- P.S.E stands for “Plain Small End”.
- B.B.E stands for “Beveled Both Ends”.
- B.L.E stands for “Beveled Large End”.
- B.S.E stands for “Beveled Small End”.
- T.B.E stands for “Threaded Both Ends”.
- T.L.E stands for “Threaded Large Ends”.
- T.S.E stands for “Threaded Small Ends”.
- B.O.E stands for “Beveled One End”.
- P.O.E stands for “Plain One End”.
- T.O.E stands for “Threaded One End
Pipe Nipple End Finishes Available
- NPT or BSP
- Beveled Weld,
- Squared Cut (for socket weld)
- Grooved
The most common types are PBE, BBE and TBE .
Swage Nipple ASTM A105 has extensive application in machining or project practice, especially in small diameter pipeline system, it is often used instead of reducing coupling.

Difference between Swage Nipple and Reducer
Difference between Swage Nipple and Reducer
Swage Nipple and Reducer are both pipe fittings used to connect pipes of different diameters, but they differ in structure and application. Swage Nipple is a short piece of pipe with different diameters at both ends, usually threaded or beveled, often used for small bore pipe size reductions. Reducer, on the other hand, is a butt-weld fitting with a larger body, available in concentric or eccentric types, and is mainly used in larger pipeline systems to smoothly change the flow diameter. In short, swage nipples are compact and suitable for small pipelines, while reducers are more common in large pipe networks.
