Advantages of Pipe Nipples
High strength
Stable performance
Quick connection speed
Easier to manage compared to other fittings
Close Nipple (or Fully Threaded Nipple)
A close nipple has no unthreaded space in the middle. The entire length of the nipple is threaded. When you screw two female fittings onto a close nipple, they will touch, or come very close to touching. This creates the tightest possible connection between two fittings.
Barrel Nipple
This is the most common type of pipe nipple. It has a short, unthreaded section in the middle. The threads on each end are tapered. This unthreaded area makes it easier to grip the nipple with a pipe wrench without damaging the threads.
Hexagonal Nipple
As the name suggests, a hexagonal nipple has a hexagon-shaped section in the middle. This hexagon serves the same purpose as the unthreaded area on a barrel nipple: it provides a surface for a wrench. However, because it is a hex shape, you can use a standard wrench or socket instead of a pipe wrench. This can prevent scratching or damaging the nipple.
Weld Nipple
A weld nipple is different because it is not designed to screw in on both ends. One end is threaded, while the other end is plain. The plain end is designed to be welded directly onto a pipe, tank, or fitting. This creates a permanent, very strong connection.
Swage Nipple
A swage nipple is used to connect pipes of two different sizes. It is a reducing connector. For example, you could use a swage nipple to connect a 1-inch pipe to a 3/4-inch pipe. They can have different end connections, such as threaded on both ends, plain on both ends, or one of each.
Grooved Nipple
This type has grooves near the ends instead of, or in addition to, threads. These grooves are used with grooved couplings (like a Victaulic coupling) to create a flexible yet secure connection. This system is often faster to assemble and disassemble than threaded systems.
Common Materials for Pipe Nipples
Carbon Steel
Carbon steel is strong, durable, and relatively inexpensive. It is the most common material for pipe nipples used in industrial applications. Black steel nipples (a type of carbon steel) are often used for gas lines and sprinkler systems.
01
Galvanized Steel
Galvanized steel is carbon steel that has been coated with a layer of zinc. This zinc coating protects the steel from rust and corrosion. Galvanized nipples are very common in water supply lines and outdoor applications.
02
Stainless Steel
Stainless steel contains chromium, which gives it excellent resistance to rust and corrosion. It is also very strong and can handle high temperatures. This makes it ideal for food and beverage processing, chemical plants, and marine environments.
03
Brass
Brass is an alloy of copper and zinc. It is highly resistant to corrosion and is a good conductor of heat. Brass nipples are a top choice for drinking water plumbing because they do not release harmful chemicals and resist corrosion from water.
04
PVC (Polyvinyl Chloride)
PVC is a type of plastic. PVC nipples are lightweight, cheap, and completely immune to rust. They are used in low-pressure, low-temperature water applications, such as irrigation, drainage, and home plumbing (DWV - Drain, Waste, Vent).
05
The Manufacturing Process
Cutting the Pipe: The process starts with a long piece of pipe of the desired material (e.g., carbon steel, stainless steel). An automated saw cuts the pipe into short, precise lengths called "blanks." The length of the blank depends on the final size of the nipple.
Chamfering the Ends: The cut ends of the blank are often sharp and rough. A machine grinds the inside and outside edges of each end. This process, called chamfering, creates a beveled edge. A beveled edge makes it much easier to start threading the nipple into a fitting.
Threading: This is the most critical step. The blank is placed in a threading machine. Cutting dies rotate around the ends of the pipe, cutting grooves to create the threads. The most common thread type in North America is NPT (National Pipe Thread). NPT threads are tapered, which means they get slightly wider toward the end. This taper helps create a tight seal when the nipple is tightened into a fitting.
Finishing and Cleaning: After threading, the nipples may have metal shavings or cutting oil on them. They are cleaned and deburred to remove any sharp edges. For galvanized nipples, this is the stage where they are dipped in molten zinc.
Quality Control and Inspection: Each nipple is inspected. Inspectors check the thread quality, length, and overall finish. They use special gauges to ensure the threads meet industry standards (like ASME B1.20.1 for NPT threads). This final check guarantees the nipple will create a secure, leak-free connection.
Application of Pipe Nipples
Plumbing:
Pipe nipples are used in residential and commercial plumbing for connecting water supply lines, drain systems, and fixture connections.
Industrial Piping:
They are crucial in various industries, including oil and gas, chemical processing, and pharmaceutical, for transporting fluids and gases.
HVAC Systems:
Pipe nipples play a vital role in heating, ventilation, and air conditioning systems, facilitating the flow of refrigerants and other fluids.
Adapting Pipe Sizes:
They allow for connecting pipes of different diameters or connecting pipes to equipment with varying thread types.
Extending Piping Systems:
Pipe nipples can be used to extend existing pipe runs or to create offsets in a piping layout.
Repairing Damaged Sections:
In case of damage or leaks, nipples can be used to replace a section of damaged pipe or to create a connection around a damaged area.
