What is a swage nipple?
A swage nipple also named reducing nipple, one end is large diameter and one end is small, they are made from forgings or formed by seamless pipes.Swage nipples are used to bring the flow of fluids from one pipe size to another pipe size. The swage nipple is divided into concentric swage nipple and eccentric swage nipple. Concentric swage nipple is mainly used for vertical pipeline; eccentric swage nipple is mainly used in horizontal pipelines.The function of swage nipples are the same as reducer the only difference is that they are generally used to connect butt welded pipe to a socket welded or screwed pipe.The swage nipple generally adopts the MSS SP-95 standard or the BS 3799 standard.
Swages contain a bore, usually matching that of the pipe onto which they are fitting. Because each end is of a different size, the bore – as well as the wall thickness and schedule – of each side can also be different. The swage ends can be plain (PBE, for plain both ends), threaded (TBE, for threaded both ends), bevelled (for butt-welding; BBE, for bevelled both ends), or a combination thereof, depending on the ends of the piping system into which the swage will be fitted.
Swage nipples are reducers for piping systems that are given their name due to the process of their manufacture.Swaging is a metal-forming technique in which the metal is plastically deformed to its final shape using high pressures, either by pressing or hammering, or by forcing the material through a die.
Swaging differs from forging in that the swaged metal is cold worked, and the output of the swaging operation is usually the finished shape: they are cold formed from two pieces slamming into each other at high pressures.These pieces are longer than reducers, and are used more extensively in higher pressure applications.
Some of the common grade swage nipples we manufacture include A234 WPB, A403 WP304,WP316 and A420 WPL6 in size range of 1/4″ through to 8″ for concentric swage nipples and 1/4″ to 4″ for eccentric swage nipples.We can offer swage nipples with plain, beveled or threaded ends. Thickness and outside diameters of swage nipples shall correspond to those of the appropriate nominal pipe size. Swage nipples are offered in threaded ends per ASME B1.20.1 and beveled ends per ASME B16.25.
We provide swages in all sizes, types, ends, and bores, in a wide range of stainless steel and other alloys.
