A nipple is a short piece of pipe that is used as a fitting to connect piping in plumbing applications. Nipple fittings are produced in various materials, although stainless steel nipples are the most common due to their strength and durability.
Stainless steel nipples are usually made with male pipe thread (MPT) connections on both ends, connecting two separate female threaded pipes and fittings. The connection allows for a watertight seal between the fittings.
Stainless steel nipples are primarily used in low-pressure piping systems, and the type of nipple used will vary with the size, temperature, and working pressure of the system. Therefore, depending on the specific application, there are various types of pipe nipples to choose from. This article will outline the uses of different types of stainless steel nipples.
Different types of stainless steel nipples are designed for different uses and applications. While there is some potential overlap between different pipe nipples, each has specific design features that determine the most appropriate use.
Barrel Pipe Nipple
Barrel nipples are tapered NPT threaded on both ends and have an unthreaded section in the middle. These are some of the most common types of pipe nipples, and due to their inherent strength and easy-to-remove design can be used in various applications to fit female threaded piping together.
T.O.E Pipe Nipple
T.O.E stands for threaded one end. T.O.E pipe nipples have one threaded end and one non-threaded end. Unlike other types of T.B.E (threaded both end) nipples, these are not used to fit piping together and are commonly used as legs for oil tanks.
Close Pipe/Running Pipe Nipple
A close pipe nipple is a stainless steel nipple that does not have an unthreaded section in the middle. These types of pipe nipples are also known as running nipples. These pipe nipples are designed such that connected fittings come very close to one another, leaving very little of the pipe nipple exposed.
Generally, close or running pipe nipples are difficult to work with as they can easily become damaged upon removal unless specialty equipment is used.
Shoulder Pipe Nipple
Shoulder pipe nipples are longer than close nipples and have a very small section of unthreaded pipe in the middle. However, this unthreaded section is not large enough to fit a pipe wrench to remove the nipple.
Hexagonal Pipe Nipple
Also known as a Hex pipe nipple, these are designed with a hexagonal-shaped middle section. This allows one to securely grasp the nipple with a wrench to tighten or remove it. This design feature provides a greater mechanical advantage than that of a normally rounded nipple. Hence, hex pipe nipples are used in various applications where nipples need to be regularly removed or replaced.
Reducing/Unequal Pipe Nipple
Reducing or unequal pipe nipples are designed to allow a female fitting with a large connection to attach to a relatively smaller one. These are normally used for piping systems where a change in pipe dimension and flow pressure is necessary.
Hose Pipe Nipple
A Hose pipe nipple is designed with a male threaded connection on one end and a hose barb on the other end. These are normally used for piping systems that require a pipe to be connected to tubing.
Welding Pipe Nipple
A welding pipe nipple has a male threaded connection on one end and a standard cut pipe on the other end. Once the unthreaded end is welded and connected, fitting a pipe to the threaded end becomes much easier. Welding pipe nipples are normally used in piping systems that require welding to connect components.
Conclusion
Given that there are so many different types of pipe nipples and so many possible applications, choosing the right one can be rather confusing. The list of pipe nipple types above, along with their potential uses, should help you choose the correct stainless steel nipples for your piping system so that you can avoid leakages, inefficiency, or some damage.
Stainless steel j-joints are used for threaded connections between industrial fittings and pipe fittings
Stainless steel nipples are used for threaded connection between industrial fittings and pipe fittings and are available in various grades, diameters and threads.
In its most basic form, the stainless nipple is a short threaded fitting with male threads at both ends for connecting other fittings. Generally speaking, there is a small threaded distance between the two threaded ends, depending on how far the fittings are to be fitted apart.
When there is no hollow tube between the two connecting ends, the part may be called a "closing nipple" or a "working nipple". In this case, the connected fittings are close together and only a very small part of the nipple can be seen externally.
Although some constructions require such a rigid fitting, the clamping of these nipples can be difficult, and the unwinding requires a tight hold of part of the thread area. This can damage it.
In cases where there is little space between the edges of the stainless steel nipple and it is threadless, this type of nipple is usually called a hexagonal nylon or a nylon with a hexagon as it has a hexagonal section in the middle.
It functions as a nut that can be fitted with a normal wrench, providing a greater mechanical advantage than a normal rounded pipe. The hexagonal or hexagonal stainless steel nipple, with a larger distance between the threaded ends, is called a "long hexagonal nipple".
For projects that require a change in tube size, you can buy a "reduction nipple". These nipples serve to move from a larger thread to a smaller one. Care must be taken when using these parts, as reducing pipe diameter may mean higher pressure and greater flow in the smaller pipe / fitting. Stainless reducing nipples often have a hexagonal center, albeit not always.
We also offer special stainless nipples called "hose nipples" for processes that require hose connection to a pipe. This nipple has a male threaded connection at one end and a hose end on the other end. Accordingly, the hose nipples may be equipotential and reductive depending on whether the hose is to be of the same size as the tubular connection or to be reduced.
A particular type of nipples are "weld nipples" which have a threaded connection at one end and a normal tube on the other. As the name suggests, this part is designed to be welded to pipelines, fittings or reservoirs. The unripe end of the weld nipples provides a larger area for the use of a solder or other welding material to make the bond stronger. The advantage of welding nipples is that, once welded, you can connect pipes or other fittings to the end of the thread much easier.
Ways to Install Hex Nipples for Optimal Performance
Hex nipples are an essential component in plumbing systems that help to connect two different pipes. They are versatile and can be used for a wide range of gas and liquid transfer applications. It is essential to install them correctly to ensure that they work optimally. This blog post will provide tips on installing hex nipples to ensure that your plumbing system functions efficiently.
Advantages of Hex Nipples optimal performance
Hex nipples provide optimal performance when it comes to plumbing and pipe fittings. A hex nipple is a short length of pipe with male threads at both ends and a hexagon-shaped middle section that allows for easy installation between threaded connections. Here are some advantages of using a hex nipple for optimal performance:
Easy Installation
Hex nipples are designed with two male thread ends and a hexagonal middle which facilitates the tightening/loosening process during installation, making them easier to install than regular straight fittings since their shape provides you more leverage while turning them into place by hand or wrench. This makes them ideal for use in tight spaces where traditional fittings can be difficult to access or maneuver around obstacles.
Durability & Longevity
Since they have two threaded end connections, they provide superior strength and resistance against leakage compared to other types of fittings, such as compression joints or flanges, which may require gaskets or seals that can become damaged over time, leading to leaks. Additionally, due to their construction materials (usually brass) they also offer corrosion resistance so there's no need for frequent maintenance or repairs due to wear down over time like there would be with plastic fittings.
Economical Cost
With its durability and ease of installation features combined, Hex nipples are considerably less expensive compared to other types of fitting solutions available in the market today because they require fewer replacement parts over the years – saving money in the long term.
Choose the Right Size
The first step in installing hex nipples is choosing the right size. Measure the diameter of both pipes that you want to join to determine the correct size and length of your hex nipples. It is essential to select the correct size to ensure that the nipple fits snugly without gaps, which may affect the performance of your overall plumbing system.
Clean the Pipes
Before you install hex nipples, make sure that the pipes are clean and free from debris. Use a wire brush to clean the ends of the pipes thoroughly. This step ensures that the nipple fits smoothly and is free from any dirt or contaminants that may affect the performance of the entire plumbing system.
Apply the Right Sealing Materials
To ensure that your hex nipples work efficiently, use the appropriate sealing materials. The most common types of sealants used in plumbing systems include Teflon tape, pipe dope, and joint compound. Applying the right sealant ensures that there is no leakage or seepage from the joints. When using Teflon tape, wrap it around the nipple clockwise to ensure that it does not unravel when inserting it into the pipe.
Tighten Properly
After applying the sealant and inserting the hex nipple into the pipe, you need to tighten it. Use a pipe wrench to tighten it firmly. However, be careful not to over-tighten it, as this may strip the threads and cause leaks. Tighten it just enough to maintain a secure connection and allow proper flow of fluids.
Test for Leaks
After installing the hex nipple, test for leaks. Turn on the water or gas supply and observe for any signs of leaks. Check for leaks around the joint and tighten it a bit more if necessary. Recheck to ensure that there are no leaks or seepages from the joint.
Conclusion
Installing hex nipples may seem like a daunting task, but with the above tips, it is a straightforward process. Proper installation and maintenance are crucial for the optimal performance of your plumbing system. However, if you are not comfortable installing hex nipples or any other plumbing system component, it is always advisable to call a professional plumber to do it for you.
