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

1" Black Steel Nipple – Built for Structural Integrity and High-Pressure Systems

The 1" Black Steel Nipple is manufactured for use in industrial and commercial-grade piping systems where strength and pressure resistance are critical. It is commonly used in conjunction with black malleable iron fittings for gas distribution, hydronic heating, and other low-pressure systems requiring threaded steel pipe components.

Product Performance Highlights

• ✅ Seamless Construction – Fabricated from Schedule 40 seamless steel pipe to ensure consistent wall thickness and durability.
• ✅ ASTM Compliant – Produced to meet ASTM A733 specifications for pipe nipples and ASTM A53 for steel pipe material standards.
• ✅ National Pipe Thread (NPT) – Precision-machined male threads provide secure, tapered connections suitable for use with compatible female-threaded fittings.
• ✅ Corrosion-Resistant Coating – Black oxide finish provides added surface protection for dry systems and indoor use.

Technical Specifications

• Material: Welded or seamless carbon steel (ASTM A53)
• Nominal Size: 1 inch
• Thread Type: NPT – Male x Male
• Standard Length: Available in close, 1", 2", up to 6" and beyond depending on application needs
• Pressure Rating: Varies by system configuration; commonly used in systems operating under 150 psi

Installation Considerations

Threaded connections should be sealed with an approved pipe joint compound or PTFE thread sealant tape. Use appropriate torque to avoid damaging threads or fittings. For gas applications, confirm leak-free installation with a pressure test before system activation.

Applications

• • Natural gas and propane piping systems
• • Fire sprinkler and hydronic heating lines
• • Low-pressure steam applications
• • General-purpose utility piping

Did You Know?

Black steel pipe nipples should not be used in potable water systems due to the absence of corrosion protection for wet environments. For water supply lines, galvanized or brass fittings are generally preferred.

The 1" Black Steel Nipple provides the mechanical strength and threaded precision required for code-compliant and dependable installations. It is a proven choice for contractors working in gas distribution, heating systems, and general utility piping.
