1 inch x 10 inch Black Steel Nipple

1 Inch x 10 Inch Black Steel Pipe Nipple – NPT Threaded Ends

The 1 inch x 10 inch Black Steel Nipple is a straight pipe fitting used for extending pipe runs or connecting two female-threaded components in pressure-rated systems. Manufactured from Schedule 40 welded or seamless carbon steel, this nipple is suitable for gas, water, and oil systems in commercial, industrial, and mechanical installations.

Material and Construction Standards

This nipple is fabricated from ASTM A53 or A106 black steel pipe with National Pipe Taper (NPT) male threads on both ends, conforming to ANSI/ASME B1.20.1 standards. The black oxide finish is intended for non-corrosive environments or where external coatings will be applied in the field.

• ✅ Material: Carbon Steel (ASTM A53/A106)
• ✅ Finish: Black (uncoated, intended for low-corrosion indoor use)
• ✅ Nominal Size: 1 inch NPT
• ✅ Length: 10 inches overall (including thread run-out)
• ✅ Thread Type: Male NPT x Male NPT (tapered threads)

Application Use

Used in natural gas, compressed air, hydronic heating, fire protection (non-critical), and oil distribution systems. Commonly installed in mechanical rooms, risers, pump assemblies, and manifold branches where threaded steel pipe is specified. Suitable for both new construction and retrofit applications where welding or grooved connections are not feasible.

Installation Requirements

Install using compatible female NPT-threaded fittings and apply appropriate thread sealant or PTFE tape to ensure leak-free performance. Align threads to avoid cross-threading and use a pipe wrench for tightening. Do not overtighten to prevent thread deformation or fitting damage.

• ✅ Sealant Required: PTFE tape or thread compound appropriate for the media and temperature
• ✅ Torque: Hand-tight plus 1–2 wrench turns is typical for steel-to-steel joints
• ✅ Support: Use proper pipe hangers to avoid excessive stress at the connection

Performance Characteristics

• ✅ Pressure Rating: Up to 150 PSI for air/gas or per schedule and application limits
• ✅ Temperature Range: -20°F to 400°F (dependent on application and sealant used)
• ✅ Non-Galvanized: For use where internal or external corrosion is not a concern, or where black pipe is code-specified

The 1 inch x 10 inch Black Steel Nipple provides a durable and code-compliant method for extending or connecting piping in threaded steel systems. Its heavy-duty construction and compatibility with Schedule 40 pipe make it an industry-standard component in pressure-rated mechanical and plumbing installations.
