Description

What is a Stainless Steel Reducer Nipple?

A reducer nipple is a short length of pipe with male threads on both ends, featuring different diameters at each end to facilitate the connection of pipes with varying sizes. The stainless steel construction ensures high strength, excellent resistance to corrosion, and compatibility with extreme temperature and pressure conditions.

Key Features of Stainless Steel Reducer Nipple

  • Material Strength – Manufactured using high-quality stainless steel (SS304, SS316, SS316L, etc.) for enhanced durability.
  • Corrosion Resistance – Superior resistance to rust, oxidation, and chemical exposure.
  • High-Pressure Tolerance – Capable of handling high-pressure applications efficiently.
  • Threaded Ends – Comes with NPT, BSP, BSPT, or custom threads for easy and secure installation.
  • Leak-Proof Connection – Ensures a reliable and leak-free transition between different pipe sizes.
  • Temperature Resistance – Performs efficiently in extreme hot or cold environments.
  • Versatile Application – Used across multiple industries for various fluid, gas, and chemical transportation needs.

Available Material Grades

  • SS304 – Most commonly used stainless steel grade with excellent corrosion resistance.
  • SS316 – Higher corrosion resistance with molybdenum for superior performance in harsh environments.
  • SS316L – Low-carbon variant of SS316, preventing carbide precipitation and enhancing weldability.
  • SS321 – Titanium-stabilized stainless steel offering improved strength and oxidation resistance.
  • SS904L – Highly corrosion-resistant stainless steel ideal for aggressive chemical environments.
