Description

What is a Stainless Steel Long Nipple?

A stainless steel long nipple is a type of pipe fitting with male threads on both ends, designed to join two female-threaded fittings or pipes. The “long” aspect indicates that it has an extended length compared to standard nipples, allowing it to bridge larger gaps between piping systems. These fittings are manufactured according to stringent industry standards to ensure reliability and efficiency in demanding environments.

Key Features of Stainless Steel Long Nipples

  • Corrosion Resistance: Stainless steel long nipples resist oxidation, rust, and chemical corrosion, making them suitable for harsh environments.
  • High Strength and Durability: Engineered to withstand high pressures and temperatures without deforming or failing.
  • Leak-Proof Connections: Precisely machined threads ensure a tight and secure fit.
  • Wide Range of Sizes: Available in various lengths and diameters to accommodate different piping requirements.
  • Versatile Applications: Used across multiple industries, including chemical, oil & gas, food processing, pharmaceuticals, and marine.
  • Standards Compliance: Manufactured according to ASTM, ASME, and other global standards for guaranteed quality and performance.
