SKU CH-Q9T6-W51NM

Schedule 80 black steel nipple, non-threaded for welding, rated 2000 psi at 150 degrees F

  • Schedule 80 wall handles 2,000 psi at 150 °F
  • Non-threaded ends ready for custom welding or flanging
  • Black steel construction meets ASTM A53 Type F Grade A
  • 3-foot length suits standard piping runs without cutting
  • 300 psi steam rating covers low-pressure steam lines

Pipe nipple for high-pressure plumbing

This 1/2-inch nominal black steel nipple is built to Schedule 80 wall thickness for demanding fluid-handling systems. The non-threaded ends suit welded installations where a permanent, leak-tight joint is required. It meets ASTM A53 Type F Grade A specifications for consistent material quality. Installers working with steam or pressurised water up to the rated limits will find it a direct-fit component.

Pressure rating and thermal limits

The nipple withstands 2000 psi at 150 degrees Fahrenheit and 300 psi steam pressure under normal service conditions. Continuous weld construction maintains wall integrity across the full three-foot length without threaded stress risers. Black steel surface handles the stated temperature range without additional coating in typical indoor piping runs. No moving parts or flow restrictions are introduced beyond the published inside diameter.

Welded connection and dimensional profile

Non-threaded ends mean the piece must be welded into place, committing the layout before final assembly. Schedule 80 wall measures 9/64 inch thick, yielding an inside diameter of 39/64 inch and an outside diameter of 53/64 inch for flow calculations and insulation sizing. Black steel finish is compatible with standard pipe coatings applied after welding. California Proposition 65 notices apply to the material composition.

Questions about this item

How do I install the 1/2 in Schedule 80 black steel nipple and what step is often missed?

Cut the 3 ft nipple to length, deburr the 53/64 in outside diameter, then weld the continuous-weld joint; the step often missed is removing all mill scale before welding.

What maintenance or replacement will the Schedule 80 nipple need over time?

Inspect the 9/64 in wall for corrosion or erosion; replace the nipple if the 39/64 in inside diameter shows pitting or if weld seams develop leaks.

What limit appears first when the nipple runs at sustained pressure and temperature?

The 2000 psi rating at 150 °F is the first limit; steam service must not exceed 300 psi WSP.
