Value Brand 3 in Pipe Nipple Threaded 6 in Schedule 40 Black Steel

SKU CH-VA01-22JDR

Threaded 3-inch Schedule 40 black steel pipe nipple, 6 inches long, rated 300 psi at 150 °F for air, gases, non-potable water and oils

  • Schedule 40 steel handles 300 psi at 150 °F
  • 6 in overall length suits standard 3 in piping runs
  • Male NPT threads on both ends for direct assembly
  • Electric-resistance weld delivers consistent wall integrity
  • Black finish resists corrosion in air, gas and oil lines

3 in Schedule 40 Black Steel Pipe Nipple

This 3 in nominal pipe size nipple is made from welded black steel and finished with a black coating. It measures 6 in overall length with a 3 1/2 in outside diameter and 0.203 in wall thickness. Both ends feature male threaded connections for joining Schedule 40 fittings. The fitting suits air, gases, non-potable water and oil lines in industrial plumbing systems.

Pressure Rating and Construction

The nipple withstands up to 300 psi at 150 Degrees F for standard service and 150 psi at 350 Degrees F for steam applications. Electric resistance welded construction provides structural integrity under these operating limits. The steel material and black finish are globally sourced to meet Schedule 40 dimensional standards. No moving parts or powered components are present, so noise and power draw do not apply.

Installation Requirements

Male threads on each end require compatible female-threaded Schedule 40 fittings such as couplings, elbows or tees. Thread sealant or tape is needed to ensure leak-free joints at the rated pressures. The 6 in length provides a fixed spacing between connected components in the pipeline. This product is restricted from sale in California due to Proposition 65 chemical warnings for cancer and reproductive harm.

Questions about this item

How do I install this 3 in Schedule 40 black steel pipe nipple without damaging the threads?

Clean both male threads, apply pipe thread sealant or tape clockwise, hand-tighten, then wrench-tighten one to two turns; over-tightening cracks the fitting.

What maintenance will this steel pipe nipple need over time?

Inspect for external rust and internal scale annually; replace if wall thickness drops below the 0.203 in Schedule 40 minimum or if leaks appear at the threads.

What pressure limit will I hit first when running hot steam through this nipple continuously?

The 150 psi steam rating at 350 °F is lower than the 300 psi water rating, so steam pressure is the governing limit.
