  • Black steel construction resists corrosion in demanding environments
  • 1 1/4 inch nominal size fits standard Class 150 fittings
  • Rated for 1145 psi at 72 degrees F for air, gas, oil and steam
  • Welded Grade B steel handles temperatures from -20 to 600 degrees F
  • 6 foot TBE length with MNPT ends ready for immediate installation

Pipe purpose and fit

This 1-1/4 inch nominal Schedule 40 black steel pipe is threaded both ends with male NPT connections for joining to Class 150 fittings. It suits installers running air, natural gas, non-potable water, oil or steam lines in commercial or industrial settings.

Coating and construction impact

The black finish provides a basic protective layer on the welded Grade B steel during handling and installation. A 6 foot length reduces the number of joints required on a straight run, which can cut assembly time and potential leak paths.

Pre-order verification points

Confirm that 1145 psi at 72 degrees Fahrenheit and 600 degrees Fahrenheit maximum temperature cover your system design pressure and media temperature. Verify that male NPT threads match the mating fittings and that local code permits Schedule 40 black steel for the intended service.

Questions about this item

Will the welded seam on this Grade B steel pipe need inspection or replacement over time?

The pipe is manufactured from Grade B steel with a welded construction rated for 1145 psi at 72 Degrees F; inspect the weld periodically for corrosion or fatigue, especially in steam or cyclic-pressure service.

What pressure or temperature limit will be reached first during continuous steam operation?

The maximum steam pressure is 1145 psi at 650 Degrees F, while the general temperature ceiling is 600 Degrees F; sustained steam use will hit the 600 Degrees F material limit before the 1145 psi pressure rating.

How hot does the pipe surface get when carrying 600 Degrees F steam all day?

At the 600 Degrees F maximum operating temperature the pipe wall will approach steam temperature; external insulation is required to manage heat radiation and prevent burns in occupied areas.
