1 inch x 30 inch Galvanized Steel Nipple

1” x 30” Galvanized Steel Nipple – Fabricated for Long-Span Threaded Connections

The 1” x 30” Galvanized Steel Nipple is engineered for use in extended pipe runs where threaded connections are required. Fabricated from Schedule 40 welded steel pipe and hot-dip galvanized per ASTM specifications, this nipple is designed to resist corrosion and maintain mechanical integrity in both commercial and industrial piping systems.

It is commonly deployed in water supply networks, hydronic heating loops, and non-potable utility systems where strength, dimensional accuracy, and longevity are critical performance factors.

Key Technical Features

• ✅ Hot-Dip Galvanized Finish Zinc coating applied after threading provides long-term corrosion resistance in both interior and exterior environments.
• ✅ Schedule 40 Wall Thickness Supports pressure-rated applications and resists deformation under mechanical stress.
• ✅ NPT Threading Machine-cut male threads conform to ANSI B1.20.1 for compatibility with standard pipe fittings and valves.

Specifications

• Nominal Pipe Size: 1 inch
• Length: 30 inches (measured end-to-end including threads)
• Material: Carbon Steel (ASTM A53 or equivalent)
• Finish: Hot-Dip Galvanized (ASTM A123 / A153)
• Connection Type: Male Threaded (both ends)
• Thread Standard: NPT (National Pipe Taper)

Installation Guidelines

Threaded installation requires the use of an approved thread sealant or PTFE tape. Threads must be free of debris, and fittings should be tightened to manufacturer-recommended torque specifications. Over-tightening may compromise sealing surfaces or damage mating threads.

Applications

This galvanized steel nipple is utilized in hot and cold water lines, process piping, air systems, and mechanical equipment connections. Its extended length is particularly suited for bridging distances without additional couplings or elbows in straight-run configurations.

Material Note

Galvanized steel is favored in non-corrosive water and air distribution systems due to its durability and low maintenance requirements. The zinc coating also offers cathodic protection, which helps prevent rust from spreading if the surface is scratched.

The 1” x 30” Galvanized Steel Nipple provides reliable performance in threaded piping assemblies requiring corrosion resistance, structural strength, and extended reach. Specify this component for applications demanding field-proven longevity and system compatibility.
