Difference Between Swage Pipe Nipple and Pipe Nipple

Pipe fittings play a crucial role in making a reliable and efficient piping system, and among these fittings, swage nipples and pipe nipples are essential components. We will explore the key differences between eccentric swage nipples and pipe nipples, shedding light on their uses, materials, and configurations.

Swage Nipples and Pipe Nipples:

Swage Nipples: Swage nipples, often referred to simply as swages, are short pieces of pipe with male threads at both ends. They are available in various materials, including stainless steel and carbon steel, and are commonly used to connect a variety of sizes and types of pipes. Swages come in two main types: eccentric and concentric.

Eccentric Swage Nipple: This type of swage nipple has one end larger in diameter than the other, making it ideal for applications where a reduction in pipe size is needed without changing the overall length of the pipe.

• Concentric Swage Nipple: In contrast, a concentric swage nipple has both ends with the same diameter, maintaining a constant size throughout the length of the swage. This type is suitable when a reduction in size is required, and the overall length is not a critical factor.

Pipe Nipples

Pipe nipples, on the other hand, are short sections of pipe with male threads at both ends. They come in various materials, including stainless steel and carbon steel, and are used to connect two female-threaded components, often pipes or fittings. Pipe nipples can have different end connections, such as beveled ends or threaded ends, depending on the application.

Key Differences:

1. Size and Diameters:

• Swage nipples are commonly used to connect pipes with different diameters, providing a seamless transition.

• Pipe nipples, on the other hand, primarily connect pipes of the same diameter.

2. Threads:

• Both eccentric and concentric swage nipples have male threads at both ends, facilitating easy installation.

• Pipe nipples are characterized by male threads at both ends, allowing them to be screwed into female-threaded components.

3. Material:

• Swage nipples and pipe nipples are available in materials such as stainless steel and carbon steel, offering durability and corrosion resistance.

4. Applications:

• Swage nipples are particularly useful in applications where a reduction in pipe size is required, and they find utility in both horizontal and vertical pipelines.

• Pipe nipples are versatile connectors used in various piping systems for seamless integration.

5. End Connections:

• Swage nipples may have different end connections, such as beveled ends, to accommodate specific requirements.

• Pipe nipples may have various end connections, including threaded ends, ensuring compatibility with different components.

Conclusion:

In summary, while both eccentric swage nipples and pipe nipples serve critical roles in piping systems, their designs and applications differ. Understanding these differences is necessary for selecting the appropriate fitting for a given piping configuration. Whether connecting pipes of different sizes or maintaining a consistent diameter, the choice between eccentric swage nipples and pipe nipples depends on the specific requirements of the application.
