Nipples are crucial for joining and extending pipelines in various pipe fittings. They are small pieces of pipe with male threads on both ends. They are used to connect or extend different pipe sections and are also available in several varieties, each designed for specific needs; pipe nipple manufacturers offer originality and functionality in plumbing systems.
What are pipeline nipples?
Pipe nipples are short sections of the pipe used to connect two pipes or fittings. They are available in various materials, including steel, brass, and copper, and are easily used for gas and liquid applications. Pipe nipples should be rated for the maximum pressure of the gas when gas applications are used. The material used must be compatible with gas, like steel or brass. On the other hand, in liquid applications, any material compatible with liquid, like copper or PVC, can be used.
Pipe nipples are present in various sizes ranging from 1/8 inch to 2 inches in diameter. Along with diameter, they can also be purchased in different lengths ranging from 1 inch to 12 inches.
Before installing them, it is important to use a binder, which can prevent leakage. A tape known as Teflon tape is the most commonly used sealant or binder for pipe nipples. Also, wrapping the tape in a clockwise direction around threads of the pipe nipple will help to prevent the binder from unraveling if the pipe nipple is held tightly. Pipe nipples are an inexpensive and versatile method to connect pipes and fittings.
15 Distinct Types of Pipes Fitting Nipples
1. Threaded Nipples
Threaded nipples are the most commonly used type of pipe nipples. They have exterior threads on both sides, so they can easily connect to pipelines.
Its important features include:
– Threaded nipples are used to connect two female threaded pipes.
– Their availability in different lengths, diameters, and sizes allows them to meet different requirements.
– Different raw materials, such as brass, stainless steel, and galvanized steel, are used in their formation.
2. Ready Cut Pipe Nipples
Ready-cut pipe nipples, as the name indicates, are pre-cut to reduce the use of the hand for cutting. They are already cut in uniform lengths and are precise.
Their importance includes:
– As it is time and labor-saving, it is used in residential and commercial areas.
– It encourages smooth coupling because of its precise and uniform length.
3. Weld Nipples
Welded nipples are made to be welded onto pipes. Its one end is fitted with male threads, whereas the other is left plain for welding. These nipples are frequently utilized in industries where welding is required to link pipes safely. Its features include:
– It is made to join permanently using welding procedures like TIG or arc welding.
– Frequently utilized in industrial settings where strong, leak-proof couplings are necessary.
– It is available in different materials, such as copper, stainless steel, and carbon steel.
4. Close Nipple
Close nipples are quite short and have male threads at both ends. They are perfect for attaching two very near female-threaded fittings. These nipples provide a small and effective connection by eliminating the necessity for a larger pipe.
– Ideal for confined areas where minimal extension is required.
– Provides a strong, compact, and secure connection without sacrificing security.
5. Hex Nipple
The central hexagonal portion of hex nipples, also called hexagon nipples, sets them apart. This design makes better flow management possible and acts as a grip surface for wrenches during installation. Applications requiring a tighter seal and flow adjustability frequently use hex nipples.
– Hex nipples are best suited for a system where pressure is high to provide a secure connection.
– It is made of different materials, such as nickel-plated steel, brass, and stainless steel, along with some other materials.
6. Swage Nipple
In pipes having different diameters, swage nipples are used because they have male threads of various sizes at both ends. This will give an easy transition between other threads’ pipes to join pipes with different diameters. Swage nipples are particularly useful when a pipe size is decreased and come in handy when a pipe size decrease is necessary.
Its benefits are:
– It maintains a smooth transition flow by joining different pipe sizes.
– These nipples require fewer extra fittings and make plumbing installation easy and simple
– It is commonly used for plumbing systems in different sectors, such as the chemical, gas, and oil sectors.
7. Seamless Pipe Nipple
These pipe nipples are made from a single piece of material, so they are continuous, smooth, and have an inside surface.
Its important features include:
– It improves fluid flow efficiency due to its reduction in the pipe’s internal friction and pressure fluctuation.
– As welded seams are not present, they provide better strength and a longer duration.
– In applications that require high corrosive resistance and proper flow channels, seamless pipe nipples are the best options.
8. Grooved Pipe Nipple
It has grooves on both ends, which makes it a faster and safer installation with grooved pipe couplings. Its important traits include:
– They are best for systems that require daily checks and balances. They can easily be assembled and disassembled.
– They offer a better connection regardless of increased pressure.
– They have different applications like industrial pipes, HVAC, and fire prevention systems.
9. Combination Nipple
– Combination nipples or hose nipples allow the direct connection with tubes or hoses. They enable direct connection with tubes or hoses and offer flexibility and adjustability.
Their significant features include:
– Its sharp ends prevent leakage and connection breakage and give a firm grip on hoses.
– It is used for various purposes, like pneumatic installations, irrigation systems, and fluid transfer.
– They are present in various sizes and materials to match different hose and tubing needs.
10. Male Adapters
– They allow connectivity of pipes or fittings with female threads. Also known as male thread adapters. Its important features include:
– They have female and male threads, one on both ends.
– They provide flexibility for joining pipes of different sizes or thread types.
– They commonly connect components in industrial, plumbing, and irrigation applications.
There are some other types of pipe nipples used for different purposes.
- Extension Nipples
- PEX Nipples
- Stainless Steel Nipples
- Brass Nipples
- PVC Nipples
11. Extension Nipples
Extension nipples, as their name indicates, increase pipe length. They have male threads on both ends. They are available at different lengths so that we can customize them according to our necessary extension.
12. PEX Nipples
The PEX nipples are made especially for PEX (cross-linked polyethylene) pipe systems. They include PEX-compatible ends that thread or solder into place, making attaching them to PEX pipes simple. Plumbing systems in homes frequently use PEX nipples.
13. Stainless Steel Nipples
These nipples are important in their resilience to corrosion and long-lasting nature. They are best for different uses, such as gas, oil, and water pipelines. These nipples are utilized in settings where corrosion and rust are issues.
14. Brass Nipples
Brass nipples are best for their range of applications because of their resistance to corrosion and high temperatures. They are frequently used in industrial settings, water heaters, and plumbing systems.
15. PVC Nipples
PVC piping systems are intended to employ PVC nipples. They resist corrosion and are lightweight. They are also very simple to install. PVC nipples are widely utilized in drainage, irrigation, and other PVC pipes.
