Black anodized steel pipe nipple with threaded NPT ends

Beck C. H.

Beck C. H. Pipe Nipple 11/2" NPTxNPT 11" Steel Grade B 300 psi 150 psi 360°F

SKU CH-BQTX-GRZRH

A 11 inch steel pipe nipple with NPT threads on both ends, rated for 300 psi at 150 degrees F and 150 psi steam at 360 degrees F

  • ColorTransparent
  • Handles 300 psi air, gas and oil lines
  • Rated 150 psi for saturated steam at 360°F
  • Welded Grade B steel resists cracking under stress
  • 11-inch NPT threads connect without adapters
  • Made in USA to consistent manufacturing standards

1-1/2 inch NPT steel pipe nipple

This 11-inch welded steel nipple connects air, gas, non-potable water or oil lines using NPT threads on both ends. It is manufactured in the USA from Grade B steel with a black anodized finish and suits industrial piping runs that require a straight 1-1/2 inch nominal bore.

300 psi at 150 °F pressure rating

The fitting handles a maximum operating pressure of 300 psi at 150 °F and a steam rating of 150 psi at 360 °F. Its solid steel wall and welded construction contain pressure without leakage, while the anodized coating resists corrosion in normal ambient conditions.

1-39/64 inch inside diameter for sustained flow

The 1-39/64 inch bore maintains consistent flow during continuous duty without the restriction that shorter fittings can introduce. Welded seam integrity and Grade B material strength prevent deformation when the line operates at the rated pressure and temperature limits for extended periods.

Questions about this item

How do I install the 11" steel pipe nipple with NPT threads on both ends, and what step is commonly done incorrectly?

Apply thread sealant to the NPT threads, then hand-tighten before using a wrench for the final turns; the step often missed is skipping the sealant, which causes leaks at the joint.

What maintenance or replacement will the Grade B steel nipple with black anodized finish need over time?

Inspect the black anodized coating and welded seam periodically for corrosion or wear; replace the nipple if the finish degrades or threads show damage from repeated assembly.

Which pressure limit is reached first during sustained steam use at 360°F?

The maximum steam pressure rating of 150 psi at 360°F is the limiting factor; it is lower than the 300 psi air rating at 150°F, so steam service hits its ceiling first.
