Black Steel Pipe Nipple

This 2-1/2 inch nominal pipe size nipple measures 10 inches in length and is manufactured from welded Grade B steel with a black finish. It is designed for use in piping systems carrying air, natural gas, non-potable water, oil, or steam where Schedule 40 dimensions are required.

Pressure and Temperature Ratings

The fitting handles a maximum operating pressure of 945 psi at 650 degrees Fahrenheit and a maximum steam pressure of 150 psi. It operates continuously between minus 20 degrees and 600 degrees Fahrenheit, making it suitable for high-temperature steam and fluid transfer applications.

Class 150 Compatibility

This nipple is rated for Fitting Compatibility Class 150, which determines the flanges and fittings it can safely join. Systems requiring a different pressure class or gravity-flow configurations cannot use this component.

Questions about this item

How do I install the 2-1/2" Schedule 40 nipple and what step is often missed?

Apply thread sealant rated for 945 psi and 650 Degrees F, then tighten to Class 150 fitting specs; the step often missed is confirming the sealant works up to the max steam pressure of 150 psi.

What maintenance or replacement will the black steel nipple need over time?

Inspect threads and welded seam for corrosion or leaks when carrying air, natural gas, oil, steam or non-potable water; replace if wall loss or cracking appears near the 600 Degrees F operating limit.

What is the first limit reached under sustained high-temperature steam use?

The 150 psi maximum steam pressure limit is reached well before the 945 psi general pressure rating at 650 Degrees F.
