How to get high quality pipe nipples?

What is a pipe nipple?

pipe nipple is a fitting, consisting of a short piece of pipe, usually provided with a male pipe thread at each end, for connecting two other fittings.

The length of the pipe nipple is usually specified by the overall length with threads. It may have a hexagonal section in the center for wrench to grasp (sometimes referred to as a “hex nipple”), or it may simply be made from a short piece of pipe (sometimes referred to as a “barrel nipple” or “pipe nipple”). A “close nipple” has no unthreaded area; when screwed tightly between two female fittings, very little of the nipple remains exposed. A close nipple can only be unscrewed by gripping one threaded end with a pipe wrench which will damage the threads and necessitate replacing the nipple, or by using a specialty tool known as a nipple wrench (or known as an internal pipe wrench) which grips the inside of the pipe, leaving the threads undamaged. When the ends are of two different sizes it is called a reducer or unequal nipple.

Threads used on pipe nipples are BSPBSPTNPT, NPSM and Metric.

Types Of Pipe Nipples and Their Uses

But no matter what the basis for the word, it is now in common use in plumbing. And what’s more, there are several different types/subsets of pipe nipples to contend with.

  • Barrel nipple: This is a type of a short tubular with a taper thread outside at each end and which is un-threaded in the middle.
  • Weld nipple: Weld nipple is used as another method of connecting tube fittings. These kind of nipples are suitable for use under extreme conditions of vibration, pressure surges and changes of temperature.
  • Swage nipple: The basic purpose of a swage nipple is to bringing the flow of fluids from one pipe size to another. These are available with plain, beveled or threaded ends.
  • Hexagon nipple: Hexagon nipples are available in a variety of threads, materials and lengths.

I’m sure there are more, but we’ll stick with those for now.

In its most basic form, a nipple is a short length of pipe with male pipe threads at both ends for connecting other fittings. You may also see them referred to as “barrel nipples”. Generally speaking, there is a short distance of unthreaded pipe between the two threaded ends, depending on how far apart you need the attached fittings to be.

When there is no bare pipe (read “unthreaded”) between the two connecting ends, the part may be called a “close nipple” or a “running nipple”. In that case, connected fittings come close to touching one another and very little of the nipple can be seen.

Although some constructions require such tight placement, close nipples can be difficult to work with, since unscrewing them requires holding tight to part of the threaded area. That can damage the threads. Plumbers who need to use them often invest in an internal pipe wrench (also known as a “nipple wrench”), which expands inside the pipe to hold it in place without damaging the threads.

In cases where you can spare a little space between threaded ends, you can use a “hexagonal nipple”, which has a hexagonal section in the middle. It functions like a nut that can be gripped by a normal wrench, providing a greater mechanical advantage than normal rounded pipe. A hexagonal nipple with more distance between the threaded ends is called, no surprise, a “long hex nipple”.

For projects which require a change in pipe dimension, you can buy a “reducing nipple.” Sometimes called an “unequal nipple”, it takes a female fitting with a larger connection and attaches it to a smaller one. Care should be taken when using these parts since a reduction in pipe diameter can mean more pressure and greater flow rate in the smaller pipe/fitting. The nipple usually has a hexagonal center, although not always.

There is a specialty nipple called a “hose nipple” for processes which require connection to tubing. That fitting features a male threaded connection on one end and a hose barb on the other. The hose barb may be the same size as the pipe connection or it may be reduced.

The final variant we will talk about is the “welding nipple,” which has a threaded connection on one end and normal cut pipe at the other. As the name implies, this part is designed to be welded to piping, a fitting or a tank. The unthreaded end of the pipe provides more surface area for the use of solder or other welding materials to make the connection stronger. The benefit of the welding nipple is that once the unthreaded end is connected, you can connect pipes or other fittings to the threaded end much more easily.

What are swage nipples?

Swage nipples also named reducing nipple, one end large diameter one end small, they are made from forgings or formed by seamless pipes. The end of swage nipple is plain, beveled and threaded. 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.

There are also available as Concentric and Eccentric type.

What is a eccentric swage nipple?

The Eccentric Swage Nipple is designed with precise configurations and is generally known for their close tolerance. This type of swage nipple is perfect for critical applications which involve vibration, high pressure, temperature and impulse. The most common of these swage nipples is to join fittings to pipes or cables. Owing to robust construction, longer service life and easy fittings, these swage nipples loosely fits together and form a permanent joint.

What is threaded nipple?

Threaded nipple is a length of straight pipe with male threads on both ends. It is one of the most popular category of pipe fittings. It is a connector or a coupling threaded on both ends. threaded nipples are used to allow plumbing to be connected to a water heater or other plumbing. They are used to fit straight end hose or pipe. A combination of threaded nipples are recommended for low-pressure discharge and suction service for various compatible liquids and not for compressible products like air, nitrogen or steam.
