1 inch x 3 inch Stainless Steel Nipple

1" x 3" Stainless Steel Nipple – Threaded Schedule 40 Pipe Segment

The 1" x 3" stainless steel nipple is a Schedule 40 pipe segment with NPT threads on both ends, manufactured for direct connection between two female-threaded fittings. Constructed from corrosion-resistant stainless steel, this fitting is suitable for use in potable water systems, chemical transport lines, and mechanical piping networks where strength, durability, and non-reactivity are required.

Fabricated to meet dimensional and material standards for threaded pipe, this component offers consistent performance in high-pressure or corrosive service environments. The smooth internal bore supports optimal flow characteristics while the threaded ends conform to ANSI/ASME B1.20.1 standards for compatibility with other pipe and fittings.

Performance Characteristics

• ✅ Material Composition: Made from 304 or 316 stainless steel depending on spec, offering superior resistance to corrosion, scaling, and pitting.
• ✅ Thread Specification: NPT male threads on both ends, machined for reliable mechanical engagement and seal integrity.
• ✅ Pressure Compatibility: Suitable for use in pressure-rated piping systems; actual pressure limits depend on temperature, media, and wall thickness.
• ✅ Clean Bore Finish: Ensures minimal turbulence and pressure drop, supporting flow efficiency in high-demand systems.

Installation Guidelines

Apply PTFE tape or pipe thread compound on male threads before insertion to ensure a leak-tight connection. Use a pipe wrench on the unthreaded portion during installation to avoid thread deformation. Always confirm material compatibility with the system media and follow local code requirements.

Applications

Commonly used in water supply systems, processing plants, chemical handling lines, food-grade plumbing, compressed air systems, and HVAC installations. Stainless steel is especially recommended for areas with high humidity or chemical exposure where galvanized or black steel fittings are prone to corrosion.

Material Reference

Type 304 stainless steel is widely used for general-purpose corrosion resistance, while Type 316 includes molybdenum for enhanced resistance in chloride-rich environments. Both meet ASTM and ASME specifications when used in piping applications.
