Swaged Nipples

Swage nipples feature a gradually reducing or expanding design, allowing them to smoothly connect pipes of different diameters.

High Quality Swaged Nipples

SSM provides Swage nipples, which are pipe fittings used to connect two sections of pipe with different diameters. They are typically cone-shaped or tapering pieces of pipe with different diameters at each end, one end connecting to a larger diameter pipe and the other to a smaller diameter pipe. Swage nipples can be used to change the pipe size in a pipeline system or as connectors within the system.

Product Description

Nominal Pipe Size (NPS/DN)
Swage nipples typically have nominal pipe sizes ranging from NPS 1/8 (DN 6) to NPS 12 (DN 300).

Minimum size: NPS 1/8 (DN 6)
Maximum size: NPS 12 (DN 300)

Materials
Swage nipples are usually made from carbon steel, stainless steel, or alloy steel.

End Connection Types

Swage nipples can have threaded, butt-welding, or other types of connections.

Manufacturing Specifications:
Manufacturing Standard: MSS SP-97
Material Standards: ASTM A234/A234M, A403/A403M, A420/A420M, A815/A815M, A858/A858M, or the corresponding ASME Specification.

End Size Configuration

Swage nipples come in different size combinations based on the design of the ends. Common combinations include:

  • 1/8 x 1/4 (DN 6 x DN 8)
  • 1/4 x 1/2 (DN 8 x DN 15)
  • 1/2 x 3/4 (DN 15 x DN 20)
  • 3/4 x 1 (DN 20 x DN 25)
  • 1 x 2 (DN 25 x DN 50)
  • 2 x 3 (DN 50 x DN 80)
  • 3 x 4 (DN 80 x DN 100)
  • 6 x 8 (DN 150 x DN 200)

Types of Swage Nipples

Concentric Swage Nipple

Both ends have the centerlines aligned, suitable for continuous flow of fluids.

Eccentric Swage Nipple

The centerlines of the two ends are not aligned, commonly used to prevent fluid accumulation or for drainage systems.

Swage Nipples Applications

Swage nipples are widely used in the following industries and scenarios:

  • Oil and Gas: For connecting different pipe diameters in high-pressure and high-temperature environments.
  • Chemical and Petrochemical: Used in chemical media transportation systems; swage nipples can be selected for corrosion-resistant materials for pipeline connections in aggressive media.
  • Water Treatment and Drainage Systems: Help adjust pipe sizes, especially the eccentric type, which prevents water accumulation.
  • Boiler and Pressure Vessel Systems: Used for pipe connections in high-temperature and high-pressure boilers or pressure vessel systems.
  • Shipbuilding and Marine Engineering: Used for pipeline connections that transport seawater or other corrosive fluids in marine environments.

More Information About Swage Nipples

Advantages

  • Applicable for Various Pipe Sizes: Swage nipples can connect pipes with different diameters, solving the issue of size differences, often used to reduce or expand pipe dimensions.
  • Multiple Materials: They can be made from carbon steel, stainless steel, alloy steel, and other materials, suitable for different media and operating conditions (e.g., high temperature, high pressure, corrosive environments).
  • High Flexibility: The ends can be configured for different types of connections, such as threaded, butt-weld, or socket-weld, meeting various pipeline system requirements.
  • Compact Structure: Compared to other reducers (such as reducing tees), swage nipples are smaller, easier to install, and save space.
  • Suitable for High-Pressure Systems: Due to their structure and material selection, they can generally withstand high pressure and temperature, making them ideal for high-pressure pipeline systems.

Disadvantages

  • Pressure Loss: Due to the sudden change in pipe size, turbulent flow or vortices may form, leading to pressure loss or flow rate changes.
  • Corrosion Risk: Although corrosion-resistant materials can mitigate corrosion, swage nipples may still experience wear or corrosion in harsh environments, especially if inappropriate materials are chosen.
  • Limited Connection Types: Some swage nipples (e.g., threaded connections) may not be as reliable in high-pressure or high-temperature conditions compared to butt-weld connections, leading to potential sealing failures.
