1/2 inch x 24 inch Galvanized Steel Nipple

1/2" x 24" Galvanized Steel Nipple – Schedule 40 Threaded Pipe for Piping Extensions

The 1/2" x 24" Galvanized Steel Nipple is a Schedule 40 pipe segment with male National Pipe Taper (NPT) threads on both ends. Manufactured from welded or seamless steel pipe and hot-dip galvanized in compliance with ASTM standards, this nipple provides corrosion-resistant performance in fluid, air, or mechanical systems requiring extended pipe runs.

Designed for use in potable water, low-pressure steam, HVAC, and general mechanical piping applications, the galvanized coating offers protection against external oxidation, making it suitable for interior or limited exterior exposure where moisture may be present.

Product Features and Benefits

• ✅ Hot-Dip Galvanized Finish – Provides corrosion resistance for extended service life in wet or humid environments.
• ✅ Precision NPT Threads – Conforms to ANSI/ASME B1.20.1 for secure, pressure-rated connections to standard fittings.
• ✅ Uniform Wall Thickness – Fabricated to Schedule 40 dimensions for consistent pressure handling and mechanical integrity.
• ✅ Steel Construction – Made from ASTM A53 or A106 Grade B pipe for structural reliability and compatibility with galvanized systems.
• ✅ Standard Length – 24-inch overall length provides extension capabilities between components or fixture tie-ins.

Common Applications

This galvanized nipple is used in water supply lines, compressed air systems, mechanical room piping, irrigation manifolds, and fire suppression components where steel pipe is required. It is suitable for both above-ground and protected outdoor installations and is commonly specified in municipal, commercial, and light industrial construction.

Installation Considerations

Apply PTFE tape or approved thread compound to the male threads to ensure a tight, leak-resistant joint. Avoid excessive torque to prevent thread galling or deformation. Ensure all mating components are properly aligned and compatible with galvanized pipe and fittings to prevent dissimilar metal corrosion.

The 1/2" x 24" Galvanized Steel Nipple is a reliable component in threaded piping assemblies requiring corrosion protection and mechanical durability. It supports field assembly where precise extension lengths and robust joint integrity are critical.
