Description

What is a Stainless Steel Swaged Nipple?

A Stainless Steel Swaged Nipple is a pipe fitting that allows for the connection of two pipes of different diameters or sizes. The “swaging” process refers to the method of tapering or reducing the diameter of the nipple to fit the adjoining pipes. This is accomplished by applying pressure to the nipple to shape it to the required size. Stainless Steel Swaged Nipples are made from stainless steel, a material known for its exceptional corrosion resistance, mechanical properties, and aesthetic appeal.

Stainless Steel Swaged Nipple Technical Specification

Material Grade

  • Standard Materials:
    • AISI 304 (UNS S30400)
    • AISI 316 (UNS S31600)
    • AISI 316L (UNS S31603)
    • AISI 321 (UNS S32100)
    • Other customized alloys as per requirements.
  • Material Composition:
    • AISI 304: Chromium 18%-20%, Nickel 8%-10.5%, Carbon ≤ 0.08%, Manganese 2%-2.5%, Silicon ≤ 1%.
    • AISI 316: Chromium 16%-18%, Nickel 10%-14%, Molybdenum 2%-3%, Carbon ≤ 0.08%, Manganese 2%-3%, Silicon ≤ 1%.
    • AISI 316L: Chromium 16%-18%, Nickel 10%-14%, Molybdenum 2%-3%, Carbon ≤ 0.03%, Manganese 2%-3%, Silicon ≤ 1%.

Size Range

  • Nipple Lengths: Available in custom lengths as per client specifications, typically ranging from 1-12 inches.
  • Diameter Range:
    • Outer Diameter: 1/8″inch, 1/4″inch, 3/8″inch, 1/2″inch, 3/4″inch, 1″inch, 1-1/4″inch, 1-1/2″inch, 2″inch, 2-1/2″inch, 3″inch, 3-1/2″inch, 4″inch
    • Wall Thickness: Sch 10, Sch 40, Sch 80, Sch 160, and custom thicknesses available.

Pressure Rating

  • The pressure rating of Stainless Steel Swaged Nipples is dependent on the wall thickness, material grade, and application conditions. The standard pressure ratings are as follows:
    • AISI 304: Up to 1500 psi (for Schedule 40 at ambient temperature).
    • AISI 316/316L: Up to 3000 psi (for Schedule 40 at ambient temperature).
  • High-pressure variants are available upon request for specialized applications.

Temperature Resistance

  • AISI 304: Temperature range from -100°F to 900°F (-73°C to 482°C) for continuous service.
  • AISI 316/316L: Temperature range from -100°F to 1200°F (-73°C to 649°C) for continuous service.
  • Higher temperature resistance is achievable with special alloys or coatings.

End Connections

  • Threaded Ends: NPT (National Pipe Thread), BSPT (British Standard Pipe Thread), BSPP (British Standard Pipe Parallel).
  • Socket Weld: Suitable for use in high-pressure systems where welding is preferred.
  • Butt Weld: Available for pipe-to-pipe connections.
  • Flanged Ends: Compatible with flat face or raised face flanges.

Surface Finish

  • Polished Surface: Available in different grades of polishing including 180 Grit, 240 Grit, 320 Grit, and mirror-finish (600 Grit) for applications where aesthetics or smoothness are essential.
  • Passivated Surface: The surface is treated to remove free iron and enhance corrosion resistance, ideal for food, pharmaceutical, and chemical industries.

Benefits

  1. Corrosion Resistance: High resistance to various types of corrosion, especially in harsh or corrosive environments.
  2. Durability: Strong and long-lasting, with the ability to perform under high-pressure and high-temperature conditions.
  3. Easy Installation: Swaged Nipples reduce the need for complicated fittings, allowing for quick and easy installation and disassembly.
  4. Leak-Proof Performance: Ensures a reliable seal, reducing the risk of leaks in critical piping systems.
  5. Versatility: Available in different material grades and configurations to meet the needs of various industries.

Applications

  • Oil & Gas
  • Chemical Processing
  • Water Treatment
  • Food & Beverage
  • Pharmaceutical
  • Marine & Offshore
