1 inch x 72 inch Galvanized Steel Nipple

1 Inch x 72 Inch Galvanized Steel Nipple – Schedule 40, Threaded Ends

The 1 inch x 72 inch galvanized steel nipple is a straight-length Schedule 40 pipe segment with threaded male National Pipe Thread (NPT) ends. It is designed for use in water distribution, compressed air lines, and other non-potable applications requiring moderate pressure and corrosion protection. This fitting allows for rigid system connections without requiring field threading or welding.

Material Characteristics and Use Considerations

Galvanized nipples are manufactured from carbon steel pipe coated with a zinc layer through hot-dip galvanization. The zinc barrier provides protection against external corrosion in exposed or humid environments. This type of nipple is intended for systems that do not convey potable water and where internal corrosion resistance is not critical:

• ✅ Schedule 40 Wall Thickness Meets ASME B36.10 standards for carbon steel pipe dimensions.
• ✅ Threaded Both Ends (TBE) NPT threads per ANSI/ASME B1.20.1 allow for direct coupling to compatible pipe, valves, or fittings.
• ✅ Hot-Dip Galvanized Coating Applied to external surfaces for enhanced protection in atmospheric and mechanical system installations.

Installation Guidance

Threaded connections should be assembled using PTFE tape or compatible pipe joint compound to ensure a leak-resistant seal. Use appropriate torque when tightening to avoid galling or damaging the threads. This nipple can be cut to length in the field if shorter runs are required, but any modified ends must be re-threaded and re-galvanized if corrosion resistance is to be maintained.

Applications

Commonly used in mechanical rooms, HVAC system piping, and industrial distribution systems. Suitable for use in:

• Hydronic heating loops
• Low-pressure gas lines (when approved by code)
• Fire protection standpipes (non-potable)
• Pump manifold assemblies

Material Limitations and Compliance Notes

Galvanized steel nipples are not recommended for use in drinking water systems due to the potential for zinc leaching and internal corrosion. Not suitable for aggressive chemical environments or pressurized steam applications. Always confirm with local plumbing code and authority having jurisdiction (AHJ) before specifying in regulated systems.
