1-1/2 inch x 36 inch Galvanized Steel Nipple

1-1/2" x 36" Galvanized Steel Nipple – Threaded Pipe Extension for Corrosion-Resistant Piping Systems

The 1-1/2" x 36" Galvanized Steel Nipple is a schedule 40 pipe segment with male NPT threads on both ends, designed for applications requiring extended reach and corrosion resistance in pressurized and non-pressurized systems. Hot-dip galvanized per ASTM standards, this fitting is used in potable and non-potable water distribution, compressed air systems, and mechanical installations where exposure to moisture or corrosive environments is expected.

Manufactured from welded or seamless carbon steel pipe and coated with a zinc-rich layer, this nipple offers enhanced protection against oxidation and premature deterioration. Its long length allows for fewer joints, reducing potential leak points in extended runs or suspended installations.

Key Features

• ✅ Material: Carbon steel base with hot-dip galvanized exterior, compliant with ASTM A53 or equivalent
• ✅ Threaded Ends: Male NPT x Male NPT per ASME B1.20.1 for compatibility with standard fittings and valves
• ✅ Nominal Size: 1-1/2 inch
• ✅ Length: 36 inches (3 feet)
• ✅ Wall Thickness: Schedule 40 standard weight
• ✅ Pressure Rating: Suitable for WOG (water, oil, gas) systems in accordance with system design parameters

Typical Applications

• Used in water supply lines, risers, and downfeed loops in both residential and commercial buildings
• Installed in compressed air systems, non-potable water systems, and irrigation piping
• Frequently used in outdoor or exposed locations where added corrosion protection is required

Installation Guidance

Thread sealant or PTFE tape should be applied to male threads to ensure a pressure-tight joint. Proper alignment and torque are essential to prevent thread damage. Pipe supports must be provided in accordance with code requirements to avoid stress on the fittings.

The 1-1/2" x 36" Galvanized Steel Nipple offers an extended reach connection with corrosion resistance suited for general construction, HVAC, plumbing, and light industrial applications. Designed to meet recognized mechanical and building standards, it is a reliable component in both new installations and retrofit scenarios.
