2 inch Black Steel Nipple Run (Close to 6 inch)

2" Black Steel Nipple – Threaded Schedule 40 for High-Pressure Applications

The 2" Black Steel Nipple is designed for robust mechanical connections in high-pressure systems. Precision-machined and threaded on both ends, this Schedule 40 fitting is commonly used in industrial, commercial, and residential piping systems requiring strength, durability, and corrosion resistance in non-potable applications.

Manufactured from ASTM A53 Grade B steel, this nipple supports standard threaded pipe assemblies in steam, oil, gas, and air systems. Its black finish offers basic oxidation resistance during storage and handling. The consistent wall thickness and threading depth help reduce misalignment and leakage risks during installation.

Performance Features

• ✅ Standard Pipe Thread (NPT) – Tapered threads on both ends conform to ANSI B1.20.1 specifications for pressure-tight sealing.
• ✅ Seamless or Welded Steel Construction – Built to handle thermal expansion, vibration, and internal pressure in demanding environments.
• ✅ Schedule 40 Wall Thickness – Provides sufficient mechanical strength for medium- to high-pressure applications.
• ✅ Cut Length Accuracy – Overall length tolerance ensures compatibility in prefabricated piping assemblies.

Installation Guidance

Use of a high-quality thread sealant (PTFE tape or pipe dope) is recommended to achieve a leak-free joint. Always verify thread engagement and alignment before pressurizing the system. Suitable for use with malleable iron or forged steel fittings, and compatible with steel or cast iron pipe.

Specifications

• Nominal Size: 2 inch
• Length: Varies per SKU (commonly 2" to 12")
• Material: Black steel, ASTM A53 Grade B
• Thread Type: NPT (tapered), both ends
• Wall Thickness: Schedule 40
• Operating Pressure: Rated for standard air, steam, oil, and gas service pressure classes

Applications

This black steel nipple is typically used in gas distribution lines, fire sprinkler systems, compressed air systems, and closed-loop hydronic heating. Its compatibility with ferrous metal fittings makes it suitable for prefabricated assemblies or field installations in mechanical rooms, utility corridors, and industrial facilities.

Note on Usage

Black steel is intended for use in systems that do not carry potable water. For water distribution systems, consider galvanized or corrosion-resistant alternatives as required by local code.

Engineered to meet the performance demands of professional installations, the 2" Black Steel Nipple is a critical component for threaded piping assemblies where strength and reliability are essential.
