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

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

The 1-1/2" x 2" Galvanized Steel Nipple is a short-length, schedule-grade pipe segment with male NPT threads at both ends. Manufactured from carbon steel pipe and coated with a zinc galvanizing layer, this nipple is used to connect female-threaded pipe and fittings in applications requiring corrosion protection and mechanical strength.

These nipples are fabricated to meet dimensional and threading tolerances specified under ANSI/ASME B1.20.1 and are suitable for potable and non-potable fluid systems, as well as low-pressure steam, gas, and compressed air lines.

Performance Characteristics

• ✅ Galvanized Zinc Coating Protects against oxidation in moisture-prone environments, extending the service life of exposed piping segments.
• ✅ Schedule-40 Wall Thickness Supports standard system pressure ranges and mechanical durability in structural or support locations.
• ✅ Threaded Male Ends Cut to NPT specification to ensure compatibility with standard iron pipe threads and accessories.
• ✅ Precision Machining Ensures uniform thread depth and clean engagement to minimize leak potential at joints.
• ✅ Code-Conforming Design Fabricated to industry standards for residential, commercial, and light industrial installations.

Technical Specifications

• Nominal Size: 1-1/2" x 2"
• Material: Galvanized Carbon Steel
• Thread Standard: ANSI/ASME B1.20.1 NPT
• Wall Thickness: Standard Schedule 40 unless otherwise specified
• Finish: Hot-dip galvanized coating per ASTM A153 or equivalent

Installation Guidelines

Apply approved pipe joint compound or PTFE thread seal tape to male threads. Use a properly sized pipe wrench to tighten without overtightening to prevent thread deformation or splitting. Inspect for burrs or coating inconsistencies before installation. Galvanized nipples are not suitable for high-temperature applications or systems requiring welding after installation.

Typical Applications

This galvanized nipple is commonly used in water distribution systems, exposed outdoor piping, pump connections, and air compressor lines. It is ideal for piping assemblies that require a corrosion-resistant threaded joint between short runs or transitions in plumbing infrastructure.

Material and Code Note

Galvanized steel components may be subject to local or regional restrictions for use in potable water systems. Verify compliance with applicable codes prior to system design or installation.
