2 inch x 18 inch Galvanized Steel Nipple

2” x 18” Galvanized Steel Nipple – Fabricated for Structural Integrity

The 2” x 18” Galvanized Steel Nipple provides a reliable threaded extension in pressure and non-pressure piping systems. Manufactured from schedule-rated steel pipe and hot-dip galvanized to ASTM standards, this nipple is designed for demanding applications requiring corrosion resistance and mechanical strength.

It is commonly specified for use in water distribution, HVAC piping, fire protection systems, and utility infrastructure where code compliance and long service life are priorities. Each unit is precisely cut and threaded to ensure consistent fit and thread engagement in field installations.

Technical Advantages

This steel nipple is engineered to meet the performance expectations of professional contractors and mechanical installers. Key attributes include:

• ✅ Hot-Dip Galvanized Coating Protects the steel substrate against rust and corrosion, especially in wet or buried environments.
• ✅ Threaded Ends (NPT) Complies with ANSI B1.20.1 standards for tapered threads, ensuring leak-resistant joint integrity.
• ✅ Consistent Wall Thickness Manufactured from standard Schedule 40 pipe, providing dependable structural performance across a range of system pressures.
• ✅ Machined Accuracy Threads are precision-cut for proper mating with couplings, tees, valves, and other threaded fittings.

Specifications

• Nominal Size: 2”
• Length: 18”
• Material: Carbon Steel with Zinc Coating
• Finish: Hot-Dip Galvanized per ASTM A153
• Connection Type: Male Threaded x Male Threaded (NPT)
• Pipe Specification: ASTM A53 or equivalent

Installation Considerations

Threaded installation requires proper sealing techniques using approved PTFE tape or pipe joint compound. Threads should not be overtightened to avoid galling or stress fractures. All installations should conform to applicable mechanical and plumbing codes to ensure system integrity and inspection approval.

Typical Applications

This 2” x 18” galvanized nipple is suitable for use in potable water systems, fire sprinkler lines, compressed air systems, and general-purpose steel piping networks. It is also widely used in industrial and commercial applications where extended reach or connection between fixtures is needed.

Material Compliance Note

Galvanized steel components are widely accepted in mechanical systems where lead-free and corrosion-resistant materials are mandated. The zinc coating provides sacrificial protection, enhancing the lifespan of the steel even in moisture-prone environments.

The 2” x 18” Galvanized Steel Nipple is a precision-engineered component for demanding applications where alignment, sealing, and durability are critical. Specify it for code-compliant, field-proven performance in your next project.
