Black steel pipe 3/4 inch MNPT 4 feet threaded both ends Sch 40

Value Brand

Value Brand 3/4" MNPT x 4 ft TBE Black Pipe Sch 40

SKU CH-H6QE-1WE1A

Sch 40 black steel pipe with 3/4 in MNPT ends for air, gas, oil, steam and non-potable water up to 1454 psi at 650 Degrees F

  • Suitable for air, gas, oil and non-potable water
  • Welded Grade B steel rated to 1454 psi at 650 °F
  • 3/4 inch nominal size with 13/16 inch inside diameter
  • Black coated finish compatible with Class 150 fittings
  • Operates from -20 °F up to 600 °F

Suitable Applications

This black steel pipe handles air, natural gas, non-potable water, oil and steam in Class 150 fittings. It is rated for 1454 psi at 650 Degrees F and operates between -20 Degrees F and 600 Degrees F. The welded Grade B construction meets Schedule 40 requirements for industrial and commercial piping systems.

Threaded Ends Ready for Assembly

Each 4 ft length arrives with male NPT threads on both ends, so no separate couplings or threading tools are required. The black coating protects the steel during storage and handling, and the 13/16 in inside diameter matches standard 3/4 in nominal pipe sizing for consistent flow capacity.

Direct Installation Considerations

Installers should verify that the 1454 psi pressure rating and 600 Degrees F temperature limit suit the system design before fitting. The pipe is not approved for gravity-flow arrangements or potable water service, and local codes may impose additional restrictions on steam or gas applications.

Questions about this item

Will the Schedule 40 wall thickness need replacement due to corrosion when carrying natural gas?

The welded Grade B steel pipe handles natural gas at up to 1454 psi and 650 °F; internal corrosion depends on gas composition and moisture, so periodic inspection is the standard practice.

What pressure limit will be reached first during continuous steam service at the rated temperature?

The maximum steam pressure is 1454 psi at 650 °F, which is the design ceiling for sustained steam use.

How much heat does the black steel pipe radiate when steam runs through it all day at 600 °F?

At the 600 °F maximum operating temperature the 13/16 in. inside diameter pipe will radiate significant heat; external insulation is normally added to control surface temperature and energy loss.
