SKU CH-ZAT0-0RXHV

A 3-inch Schedule 40 black steel pipe nipple with threaded ends, rated for 300 psi at 150 degrees Fahrenheit

  • Schedule 40 wall thickness rated for 300 psi water pressure
  • Electric resistance welded seam meets ASTM A-53 Type E standard
  • Threaded MNPT both ends for direct pipe connection
  • Black steel construction handles 150 psi steam service
  • 5 inch overall length fits standard 3 inch nominal piping

3-Inch Schedule 40 Pipe Nipple

This 3-inch nominal black steel nipple measures 5 inches overall and is threaded on both ends with MNPT connections. It is manufactured to ASTM A-53 Type E and ASTM A-733 Grade B standards for general plumbing and piping applications. The welded construction uses electric resistance weld pipe weld type for structural integrity.

Pressure Rating and Thermal Limits

The fitting handles a maximum pressure of 300 psi at 150 degrees Fahrenheit and a maximum steam pressure of 150 psi WSP. Black steel material provides durability for standard water, gas, and steam distribution systems within these limits. The 13/64 inch wall thickness supports the Schedule 40 pressure class for reliable service.

Threaded Both Ends Connection

This nipple features male National Pipe Thread on both ends for direct installation into female threaded fittings without additional adapters. The 3 1/2 inch outside diameter matches standard 3-inch nominal pipe sizing for compatibility with existing Schedule 40 components. Buyers needing a different length, diameter, or unthreaded ends must select an alternative fitting.

Questions about this item

How do I thread the 3 in MNPT ends into my fittings without cross-threading the Schedule 40 pipe nipple?

Start each MNPT end by hand for at least two full turns before using a pipe wrench on the 3 1/2 in outside diameter; this aligns the tapered threads and prevents the 13/64 in wall from galling.

Will the black steel nipple need coating replacement or corrosion inspection over time in a water system?

The black steel surface has no factory coating; plan to inspect for rust annually and apply a compatible pipe sealant or external wrap if the system sees oxygenated water.

At what temperature does the 300 psi pressure rating of this ASTM A-53 Type E nipple begin to drop?

The 300 psi rating is specified at 150 degrees F; above that temperature the allowable working pressure decreases per the ASTM A-53 Grade B pressure-temperature curve.
