1-1/2 inch x 10 inch Steel Nipple

1-1/2" x 10" Black Steel Nipple – Threaded Pipe Segment for Mechanical Piping Applications

The 1-1/2" x 10" black steel nipple is a Schedule 40 pipe segment with NPT (National Pipe Taper) male threads on both ends. Manufactured from welded or seamless black steel pipe per ASTM A733, this fitting is intended for use in general-purpose pressure piping systems including water, steam, gas, and air distribution.

Ideal for extending piping runs or bridging pipe sections in confined installations, this nipple provides a durable, pressure-rated threaded connection compatible with steel pipe and fittings. Its black oxide finish offers basic resistance to oxidation for use in non-corrosive environments.

Product Features

• ✅ Material: Carbon steel with black coating, suitable for indoor utility systems and mechanical applications.

• ✅ Schedule: Schedule 40 wall thickness for standard-pressure service.
• ✅ Manufacturing Compliance: Conforms to ASTM A733 for threaded steel pipe nipples.

Technical Specifications

• Nominal Size: 1-1/2 inch
• Overall Length: 10 inches
• Thread Type: NPT x NPT
• Pipe Specification: ASTM A53 or equivalent

Installation Guidance

Threaded steel nipples should be installed using appropriate sealants such as PTFE tape or pipe dope to ensure a pressure-tight seal. Avoid over-torquing, which may cause thread deformation or damage to mating components. Thread alignment and system support must meet applicable mechanical code requirements.

Common Applications

This nipple is widely used in:

• Hydronic and steam heating systems
• Natural gas and propane piping
• Compressed air lines
• Fire sprinkler and pump assemblies

It is suitable for both new construction and retrofit installations in commercial, industrial, and residential systems where Schedule 40 black steel pipe is specified.

Note on Material Suitability

Black steel pipe is not approved for potable water systems. It is primarily used for non-potable applications due to its uncoated interior surface and susceptibility to corrosion in water service.

The 1-1/2" x 10" black steel nipple delivers dependable performance in threaded piping systems where strength, pressure tolerance, and code compliance are required. Its precise threading and robust construction make it a trusted component for professionals across plumbing and mechanical trades.
