2 inch x 12 inch Galvanized Steel Nipple

2" x 12" Galvanized Steel Nipple – Threaded Schedule 40 Pipe Segment

The 2" x 12" Galvanized Steel Nipple is a straight pipe segment with male NPT threads on both ends, used to connect two female-threaded fittings or components in pressure-rated systems. Manufactured from Schedule 40 carbon steel and hot-dip galvanized to ASTM A153 standards, this nipple provides enhanced resistance to rust and mechanical damage in water, air, and oil service applications.

Each nipple is precision-machined to conform to ANSI/ASME B1.20.1 for NPT threads and ASTM A733 for dimensional tolerances, ensuring consistency across installations and reducing the likelihood of joint failure.

Key Performance Characteristics

• ✅ Hot-Dip Galvanized Finish – Coated for corrosion resistance, suitable for both indoor and exterior installations.
• ✅ Threaded Male Ends – National Pipe Taper (NPT) threads on both ends for secure mechanical joints in piping systems.
• ✅ Carbon Steel Substrate – Supports high working pressures and maintains structural integrity under mechanical stress.
• ✅ Schedule 40 Wall Thickness – Standard-duty pipe section suitable for water, air, and non-corrosive fluid distribution.
• ✅ Precise Length – 12-inch overall length including threads, with engagement depths suitable for standard fittings.

Technical Specifications

• Material: ASTM A53 carbon steel
• Coating: Hot-dip galvanized to ASTM A153
• Size: 2 inch nominal pipe size
• Length: 12 inches overall (including threaded portions)
• Wall Thickness: Schedule 40
• Thread Standard: NPT (ANSI/ASME B1.20.1)
• Manufacturing Standard: ASTM A733

Typical Applications

Used in low- to medium-pressure mechanical systems including:

• Potable and non-potable water distribution
• Compressed air systems
• Oil and gas transfer lines (non-sour service)
• Outdoor risers and utility stubs

Installation Notes

Apply a pipe-thread sealant or Teflon tape on threads before installation. Use appropriate wrenches on the flats near the threaded ends to avoid damage to the pipe. Over-tightening can cause thread deformation and leakage. Do not weld galvanized components unless the coating is safely removed beforehand.

Did You Know?

Galvanized steel pipe is commonly used in environments exposed to moisture due to its zinc coating, which forms a sacrificial barrier against oxidation. However, it is not recommended for highly acidic or alkaline systems without appropriate lining.

The 2" x 12" Galvanized Steel Nipple offers mechanical reliability and corrosion resistance suitable for a range of piping installations. Its compliance with standardized manufacturing and threading protocols ensures integration with existing threaded pipe systems in commercial and residential settings.
